Data Recovery/Datenrettung & Securing Data On Computers

Data recovery or Datenrettung is the process by which the data is recovered from damaged or inaccessible storage media. Data recovery is done from storage media like CDดs, DVDดs, Floppies, Hard disks, Magnetic tapes etc. There are two reasons due to which the data becomes inaccessible. They are logical damage and physical damage to the storage media.

Physical damage to storage media can occur in many ways. Magnetic tapes can break, get crumpled or dirt may settle on the tapes. CDดs and DVDดs can have scratches or the metallic layer may get damaged. Magnetic heads in hard disks can crash or motors may fail. The floppy is notorious for failing frequently due to bending, overheating, cold, dust etc.

There are other reasons like fires, electrical surges etc that can cause data to become inaccessible or lost. There are many methods by which data can be recovered from magnetic media or optical media. The methods most commonly used are Magnetic Force Microscopy (MFM), Scanning Probe Microscopy (SPM), Magnetic Force Scanning Tunneling Microscopy (STM) etc.

In these methods a sharp magnetic tip is placed closed to the surface to be analyzed. It interacts with the stray magnetic field. An image of the data is generated and then repairs are carried out on logical damage and thus the data is recovered. Many companies carry out data recovery.

Logical damage is the damage to the file system. It is not physical but a software problem and also tells us that we need to be cautious and have a quality system for data recovery, datenrettung. It generally occurs due to power cuts, system crashes etc preventing file system structures from being written resulting in file system being left in an inconsistent state.

Logical damage is more common than physical damage. This may cause strange behavior like infinitely recurring file directories, loss of data, system crashes, hard disks reporting negative space etc. The end result is that the operating system cannot mount the file system.

Most operating systems come with repair facilities like, Linux has fcsk utility, Mac has disk utility and Windows has chkdisk facility. There are other specialized programs available which have better repair facilities than the operating systems.

There are also other systems called journaling file systems like NTFS, EFS (used in Windows XP), ext3 and xfs which can be reverted back to their earlier consistent state. These file systems reduce the amount of data loss.

Data back up is the best way to prevent loss of data and itดs the most common system for data recovery, datenrettung. The simplest method is to keep data on drives on which the operating system is not loaded. The other method is to write data on magnetic tapes, CD’s or DVDดs or have online backup.

Backups are very important for databases. Data backup is of 3 types. Full backup means backing up all data. Incremental backup means backing up of only the files that have changed. Differential backup is a mixture of these two. There is another method called continuous data protection in which when data is written to a disk, it is also written to another computer in a network.

Most private persons with a computer do nothing in advance, they just use their computers. Too late, when an incident has happened they learn about data recovery or datenrettung.

Data Recovery and Your Computer

Have you ever wondered if what you know about data recovery is accurate? Consider the following paragraphs and compare what you know to the latest info on data recovery.

Sooner or later your company could become the victim of a natural disaster, or something much more common like a lightning storm or downed power lines.

Just because your company may be a small business doesn't mean it's immune to data disasters. If a small business does not have a good and tested disaster recovery plan in place when disaster hits they may never fully recuperate and it may even cause them to go out of business. Sometimes even a data recovery service is unable to be of any help.

Following are some questions that should be answered in order to give you some idea of what you need to do to that will help you if you do have a data disaster situation.

Do you know where your company's most important data files are located?

Are these files being backed up and by what means?

How often do you run these data backups and are they verified and tested?

Do you have automated controls that correctly and on a consistent basis do the backups?

Do your data backup tapes go off-site and how often?

Do you have some kind of security against tampering or theft of your data backups?

Do you keep your servers, routers, hubs, and phone system controllers in locked areas to keep them more secure?

Does just anyone have access to your servers and your other technology assets or do you limit access to at least two, but no more than four people?

Do you run a locally securable operating system, such as Microsoft Windows 2000 Professional, Microsoft Windows XP, or Microsoft Windows NT Workstation 4,on the company's desktop PCs and notebooks?

Do you have any confidential data stored locally on any desktop PCs or notebooks? Are any of these systems running an inherently in-secure operating system, such as Microsoft Windows 9x or Microsoft Windows Me?

Do you prevent unauthorized boot-ups or tampering with BIOS configuration settings by using power-on passwords?

On your desktop PCs and notebooks, how are main updates, service packs and releases kept current?

The bottom line is that you can't plan when a data disaster may strike but taking a few steps beforehand may help with your company's survival in the days and weeks following a disaster.

Data Recovery And Back Up For Email Clients

Booting issues, virus attacks, or corrupted file systems are very much present in any exchange or mail servers and can cause many of your archived email messages to apparently disappear.

Data Recovery - Your Next Option To Safeguarding Information

The realization about the need to prepare for safeguarding crucial data on your hard disk may come a little too late when the computer or the hard disk has crashed. Data loss could mean, for a small business, going out of business unfortunately, sometimes permanently. Rebuilding years of data is out of question. It is pertinent to know the whys and hows of data loss in order to understand data recovery better.

Important Causes of Data Loss
What you hoped will not occur, perhaps because of no reason, could always hit you hardest unless you are safeguarded against them. Computer running slowly could be because of spyware scrupulously installed could be working behind screens to destroy or transmit data to their masters eventually causing hard disk to crash. Others like electric storms, power surges, mechanical failures, fires & floods and user errors (sometimes in disregard of warnings) could affect your computer without any or sufficient warning.

You could also loose data because of sudden but unintended deleting of files or programs. Accidental disk format, virus attack, partition loss are some more causes for data loss.

Data Protection
Data protection is the best policy than ruing over the loss. You can make use of trusted data backup software which automatically backup your data regularly, if you can’t do it yourself manually. Keeping backup of backups will safeguard you against the worst eventualities, too. Turn off your computer immediately as you hear strange noises like creaking run of hard disk. It is also wise to unplug power cords, modem and telephone cables when you are going out of home or office for a long time.

Data Recovery
The first thing you need to understand when dealing with data recovery is not loosing cool. Never act in haste and don’t attempt data recovery yourself unless you are an old hat at that. Call for professional help from your area and who you know.

Data recovery software does a neat job in most of the cases. There are quite a few reliable softwares available, no matter what platform your computer operates on. Data recovery softwares are available for Mac, Windows, Linux, and so on. Don’t attempt to use the software yourself out of gut feeling. If you must, check for user friendly personal packages.

An average company in US alone spends anywhere between $100,000 and $1 million in total for desktop-oriented disasters. This should more than emphasize the need for data safety and disk recovery.

Data Recovery - What To Do When Your Hard Drive Fails

How many times have you experienced that sickening feeling when your hard drive suddenly fails? How many times have you experienced that your hard disk just does not boot and all the data may be gone forever? A hard drive failure is one of the most common problems and worst nightmares faced by computer operators all over the world. Precious data is lost either at home or in big corporate environments. What can be done in these situations? Well, there are certain solutions that can be performed by you in order to revive your hard drive. We will talk about the solution later. First, let us discuss why a hard drive fails.

Whether the data on the hard drive can be recovered or not depends on the extent of the problem. A hard drive can be damaged due to firmware corruption, electronic failure, mechanical failure or a logical failure. Many times your hard drive may lose data due to the combination of the above mentioned factors. A hard drive may also develop bad sectors due to which the data on those sectors is lost or becomes unreadable.

Firmware refers to the information used by the computer to interact correctly with the hard drive. If the firmware fails or becomes corrupted, then important data on the hard drive is lost. In case of an electronic failure there maybe occur an electrical surge that can knock out the controller board on the hard drive and make it unusable. However data can be recovered by data recovery experts who use special data recovery software. Swapping the controller board with another one can prove to be dangerous as the information on the controller board is unique to the hard drive on which it is fitted. In comparison to electronic failure a mechanical failure can turn out to be worst as data recovery can almost become impossible. Mechanical failure includes head crash and also read/write head failure. Head crash can occur due to physical shock, power surges and movement of the computer. Next come the logical errors. Logical errors have nothing to do with the hardware part. Logical errors can occur due to corruption of the file system on the hard drive or improper entries in the file allocation table.

In case of hard drive failure it is vital to call the data recovery experts. In most cases, the information on the hard drive is important and you cannot bear to lose it. The experts enhance the possibilities of hard drive recovery in the case of failure of hard drive due to software malfunction, virus attacks and other reasons mentioned above. Data can be recovered on any type of operating system including all versions of Windows as well as Apple Macintosh, Novell, Linux, Unix and also on all types of file systems like FAT, FAT32, NTFS, NTFS5, HFS, HFS+, NWFS, EXT2 and EXT3. The experts may take the hard drive to their workshop in order to recover the lost data and then return it to you in a few days. Most of the data recovery experts have their own laboratories that are involved in testing the hard drives and repairing them.

Loss of data is the last thing that you as the customer would ever want. This is where the data recovery experts come into the picture. They cannot extract only data from hard drives, but recover data also from tape drives, cds, dvds and other important storage media. You as the consumer can take up some preventive measures like backing up all your important data at least once a week. Windows has its own feature rich backup program. There are other backup software programs available in the market that can avert a possible disaster.

Besides the concern of recovering your data, another problem is the time it may take for an expert to help. This can be a slow and tedious process. I recommend having a second complete computer source such as a laptop (for portability) that you can continue your work. This way you are never completely down and you can share important data between the two.

Data Recovery - It May Not Be To Late After All

Definition of Data Recovery

The salvaging of lost data or making available the previously damaged data stored on various damaged media such as hard disk drives, magnetic tapes, magnetic disks, zip disks, CD-Rom, flash cards and other storage media is known as Data recovery. For example the data of a file which has been deleted by some accident can be recovered again.

ท Data Recovery Service Providers

There are various Data Recovery Service Providers who are working for 24/7 in order to provide their customers with the best available data recovery services. These service providers have highly trained staff and they are continuously improving the process technology and their quality systems. These providers allow their customers to recover every important piece of data from all the popular file systems in case of accidental file deletion, malfunctioning of software, formatted hard drives, damaged or deleted partitions and erased or corrupted by a virus.

These data recovery service providers offer a complete range of solutions for the restoration of lost data. The different softwares used by these providers are compatible for all the Microsoft Windows Editions, Apple Macintosh, Sun Solaris, AIX, Linux and Unix operating system. They also provide data recovery from different file systems such as FAT, NTFS, HFS, HFS+, NWFS, EXT2 and EXT3 file systems. They prevent the various important data of our computer by different data safety and data security softwares from unwanted accessing of data, corruption, modification or deletion by another user or from various harmful programs such as viruses, spy ware, Trojan horses, etc.

ท Some common Software used in Data Recovery

There are different data safety and data recovery softwares for hard drive data recovery. Some common software used in Data recovery are mentioned bellow.

Data Recovery with Fire: The FIRE is a portable bootable cdrom based software which can provide an immediate environment to perform data recovery which includes different forensic analysis, virus scanning, incident response and vulnerability assessment.

Data Recovery with LDE: The LDE or the Linux Disc Editor was originally made to recover the deleted files in Linux. The simple curses interface of the LDE resembles very much to the old version of Norton Disk Editor for DOS.

NT Data Recovery: The NT Data Recovery software provides read access to the NTFS drives in the MS DOS environment. The functionality of this software includes support for files with long names and as well as compressed and fragmented files. The NTFS Reader for DOS allows the files to copy them from NTFS to FAT volumes in network drives.

Data Recovery with PC Inspector: The PC Inspector File Recovery software is compatible for NTFS and FAT file systems. It has the capability to recover files with the original date and time stamp and can also restore them to the network drive. They can also recover many lost files even when the header entry is not available. The software can find partitions automatically on FAT systems even if the boot area/sector has been damaged or erased. The PC Inspector File Recovery software offers a user friendly interface that scans the hard drives and automatically recovers the files from the deleted folders.

Data Protection And Hard Disk Recovery Go Hand In Hand

When it comes to hard disk recovery, the best method is to insure that you will never need it. Besides making frequent backups, the following measures will keep your system running smoothly.

Antivirus Protection

New viruses are invented every day, and system security is a concern for every business. Malicious software can damage your system to the point where it will not even boot up. The latest versions of Windows are the favorite targets of malicious programs such as spyware and viruses, and it is helpful to use 2 or more antivirus/anti-spyware programs to prevent destruction or theft of your data.

Spyware Scanner

The clues that spyware is on a computer include a barrage of pop-up ads, a hijacked browser,a sudden or even repeated change of your computer’s Internet home page, the appearance of a new toolbar or new screen icons, malfunctioning keys, random error messages, and most of all, sluggish computer performance. Any sytem with access to the internet is prone to this problem, but there is software to block spyware installation. In addition, make sure all employees using the office network do not download from unknown sites, and set your internet browser security at "Medium" or higher. Install individual firewalls to prevent uninvited users from accessing your network. A firewall blocks unauthorized access to your computer and will alert you if spyware already on your computer is sending information out. Purchase an anti-spyware program from a vendor you know and trust. Set it to read on a regular basis, at least weekly and if possible each time you run your computer. Delete any programs the anti-spyware program detects on your computer.

Computer Maintenance

The best way to avoid having to use file recovery software is to be sure that no corrupt data is stored on your computer. Companies like Norton sell disk optimization programs keep your network running at top speed, correct problem files and maximize the available space on your hard disk. Run disk optimization and anti-virus programs at least once a week.

Hard Disk Recovery

There are disk recovery applications specifically geared to recovering files of a certain format, like graphics files as opposed to word document files, and there are general-purpose programs to hunt for any type of misplaced file regardless of the format. There is no program on the market that can guarantee recovery of every lost file, but you are able to increase your chances for recovery by selecting the appropriate program for the file you are trying to save.

Do-it-yourself programs are a lot less expensive than hiring a data retrieval company that specializes in information recovery, and to save money you should at least attempt to utilize of this type of program before calling a professional.

In addition to recovering deleted files, there exists information recovery programs that can restore files after you have formatted the drive, after a power failure, natural disaster, or even files damaged by a computer virus.

RAID

RAID is short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ 2 or even several drives in combination to improve data storage fault tolerance and performance. RAID disk drives are frequently installed on servers but can also run on individual computers. Because of the duplication of data, it is possible to recover files from one or another disk when the need arises.

As you might expect, RAID disk repair is quite a complicated process. However it is one of the most foolproof methods of data storage because the RAID architecture strategically distributes information randomly across the array. However, this sort of architecture demands the services of a recovery professional.

Data protection

S2s Ltd is a UK provider of network consulting and implementation services
that needed data protection to ensure business continuity, even in the event of a server breakdown.
s2s was previously using disk-to-tape to back up all the various systems the business was running on.
Backing up and recovering data was not only a very complicated and time-consuming process, it was also very unreliable. When retrieving data
from the tapes, once they had been delivered back to s2s, a lot of the data from the tapes was irretrievable.
SecurStore’s online solution automatically transfers data offsite in real-time, eliminating the risk of having backups located onsite in case of a disaster or loss of data during transportation to an offsite location. Data is transmitted and stored offsite in a state of the art data centre on a reliable disk subsystem, which is in turn duplicated and backed up onto a second disk sub-system located apart from the primary disk sub-system.
Due to the nature of the business, s2s runs on a variety of operating systems. Most of its servers are Linux-based and some of them are Mac-based,
because many s2s employees use Apple Macintosh machines. It also has the obligatory Windows applications and operates with a SAN architecture. SecurStore also needed to take into account the fact that most of the s2s servers are virtualised and that s2s already had a NAS (network-attached storage) system in place.
The backup service uses many defense mechanisms, such as strong
authentication, data encryption, password protection and client and
system side log legitimate users at s2s to perform a data recovery
when needed.
SecurStore backs up the critical data of s2s (120GB) online on a continual basis, so that from the moment a server goes down, all the data can
be quickly retrieved online. The remaining less critical 80GB of data is either backed up to SecurStore’s Backup Lifecycle Management (BLM) offline service, or backed up by the outsourced provider.

SecurStore is suitable for businesses that need to protect data from a few gigabytes to terabytes. The service ensures that any data held on PCs, Macintosh computers, file servers and application/database servers is securely backed up. SecurStore supports many platforms including Windows
NT/2000/2003/XP along with AS-400 iSeries, Unix and Linux. SecurStore can also protect a wide range of databases including Oracle, SQL, Exchange, Lotus Notes and DB2.

Data Disaster Recovery

Data can be restored immediately to either the original server or an alternate server. Restores can also be redirected to an alternate physical location if the original office is no longer available. The server disaster recovery solution lies in having devices and technologies available which allow us to restart the vital information systems in a shorter time period than the estimated critical. These mechanisms, and all the associated plans of actions, are known as data disaster recovery.

Why should I have a data back up and recovery system!
By not having a data center disaster recovery plan, you are quite simply, putting your business at risk; don’t take chance with your vital data. Would you leave any other aspect of your business to chance? Not really. Always be prepared for a natural calamity or any disaster, don’t leave any if’s and but’s, leave no stone unturned when it comes to backing up your important data.

Care should be taken while selecting a data disaster recovery services. The reason being your computer backup systems are the core piece of every data center disaster recovery plan.

The reasons for data loss are endless, human intervention, hardware failure, software failure, natural disaster, loss, theft, we can go on, but we can be sure of one thing, as time goes by the list will get longer and longer.
Ever had anything stolen or lost anything before?

I have been in the IT industry for some 25 years now, and as you can imagine, I have heard some bizarre stories of how computers and servers have been stolen. Laptops stolen from back seats of cars (data lost), a colleague forgot he left his laptop on the roof of his car; problem is he realized when he was 160 miles down the road (lost data). My friend’s office was broken in twice in two nights, first time resulted in loss of desktop computers and totally trashed alarm system (some data loss), and second night was to take the servers along with the backup device and media! Apparently the heavy stuff was stolen the second night as the thief’s had more time due to the alarm not being repaired quickly enough (total data loss and company ceased trading within 8 months). Save yourself money; prevent data loss in the first place by implementing a data backup plan.

Hardware Failure
If you have managed to never lose your laptop or have you whole IT infrastructure stolen then well done, so now let’s prepare ourselves for hardware failure. There are mainly only three mechanical parts within a laptop, computer or server; 1) hard drive, 2) backup drive 3) CD or DVD. Hard drives do fail and if it has not happen yet it will. Don’t get me wrong, if you take a failed drive to an expert, they will probably get most of your data back (phew) but expect to pay in excess of ฃ5000 for the pleasure (not phew). Save yourself money; prevent data loss in the first place by implementing a data backup plan.

Fire or Disaster (natural or not).
I live in the UK, it’s a lovely place as we don’t have issues with forest fires, earth quakes, and hurricanes etc. so there will never be any large natural disaster which will wipe out the majority of a city. This is what I thought until the Bunsfield oil refinery blew up and flattened everything within a 3 mile radius. There are a million and one reasons and scenarios I can give you illustrating why you should backup your business data. We all know the practice of data backup is nothing more than good common sense. Mission critical or sensitive data you don't want or can not afford to lose should be secured. PROTECT YOUR DATA! If you honestly think you do not need to backup your data because you will never lose it, please stop reading this article now and go and do something less boring.

Let’s talk about the various ways of securing your data and other backup services. If you take the following on board you will be able to find the solution which will best suit you or your company.
Backup to CD solution.

To backup your file data to CD is easy, it may be time consuming to do this every night and you will have to be disciplined to put up to an hour aside to carry out this task every night. To backup data to a CD drive is not an automated process and we all know people get busy. Once you have backed your data to CD please always verify that the data is actually on the CD and then take it home with you. There is no point leaving it to be stolen or destroyed by fire along with your hardware.

Please do not us a CD to archive data (safe documents for a long time) as I would not expect this form of media to remain stable for more than 2 years.
Backing up to CD has many limitations but it is certainly better than not backing up your data at all.

RAID – Not backup but will protect your server disks.
All servers should be given every opportunity to stay alive, running a RAID configuration will help prevent data loss due to hard drive failure. If you have 3 drives running in a RAID 5 configuration, your server will tolerate a single drive failure. RAID will not protect you from fire, flood, theft or any other disaster waiting to happen, but does offer business continuity.
This solution doesn't usually protect you from theft as the extra hard drives for RAID storage are usually installed in your computer or in other equipment on site. It usually won't protect you from fire either so this method does have its limitations.

Secure Offsite Data Backup and Recovery via a third party organization.
Offsite Backup or Backing up via the Internet methods are usually associated with larger enterprise companies. In the past the high cost of high speed connectivity has been prohibitive to smaller companies.
This method of data backup is now become totally accepted and is gaining momentum around the globe. The main reason for such grown is because the price of high speed internet connections has greatly reduced, virtually every business and home is connected to the internet via a minimum 2MB pipe as a result it is now possible to backup high volumes of data to a secure offsite data centre.

For me, the best element of an offsite backup solution is not the high encryption security levels in place, the price or the purpose designed replicated infrastructure where your data is stored, but it is the fact that an offsite backup solution is a totally automated process. Set and forget, once you have set the software to backup your data at a certain time of every day you can just forget it and let it get on with its job of protecting your data.
If I controlled your backup process, I would implement all three of the options mentioned. A RAID system for business continuity, offsite backup to securely protect all my business data, and to enable a quick restore, a CD backup of just my mission critical data which will keep my business running.

Consequences of data loss and Why should Offsite Backup be used

There is a calculated trend in all business corporations and firms: when the enterprise is getting bigger, its support of data increases its complexity, volume and value. The larger your enterprise is, the more significant your data files become. The traditional tape backup can no longer produce in-depth data information about all the important features of your business. That’s why many people get acknowledged to a more adequate file protection. A secure offsite backup system can be the possible solution. Business owners and offices managers have got it straight: if the business is to flourish, precise data information storage should be used.

Offsite backup systems offer something, which no other data store can do: they protect to the greatest extent all your files. But why should they do that, you may ask. Imagine you are a business owner. You have your own office computer, which is crammed up with all the valuable info. Well, what if the computer gets stolen, or a short-cut puts it out of practice? What will happen to your enterprise? If you are still not convinced enough to the rational extent, let’s consider the following statistic data. 1 in every 4 computer users suffers a critical data loss every year. Last years over 500,000 were stolen. Disk and other hardware failures are so numerous that major disk and computer manufacturers/resellers are reducing their warranties to 12 months. Over 25% of data loss is a result of computer program errors, software viruses and natural disasters (factors completely out of your control). 50% of businesses that lose their data never open their doors again. Of those businesses that do manage to stay open, 90% end up failing within two years. Data loss will cost business an estimated ฃ12 Billion this year.

Still not believing? Consider the following fact: computer experts say that once data is lost, it can no longer be recovered to the full. Some data that contains pieces of valuable information will be forever lost in the digital space, with no hope of getting it back. Disaster recovery planning (DV) often fails to extract the lost files in the similar way as they were before the disaster struck. This happens because of the various regulations and compliance, which occur during the recovery process.

Data loss can happen to anyone, no matter how good the tape protection system is. There is no tape backup that can comprise all the valuable information without omitting some precious stuff. Text documents, financial records, contact records, address books, email messages and databases that you have created on your computer or servers may disappear forever unless you take a serious action to prevent it. The lost files are hard to recover, and it takes a lot of precious time and nerve-racking to recover even to the approximate extent the ruined system as it was before the disaster. The value of data highly exceed the mere cost of your computer or server, as you have to pay a great amount of money for reproducing the whole information as it was before the crack down. So, the most reasonable thing to do, if you don’t want to spend a lot of money afterwards, is to re-ensure your system using secure online backups.

Even though that is the sacred truth, most people avoid taking backup precautions. They leave their data files unprotected, and thus expose their business on the danger of bankrupt. Why do people do it? Because of laziness, because they don’t want to spend additional money, or just because they think that would never happen to them. Is it so hard to take some pre-consideration and backup your data? Sooner or later, everyone gets a strike in their unprotected file systems. Then it is too late to split hairs over the lost information. You should better take the action in advance and construct a data backup system, so that your files are fully protected and your business is ensured.

Computer Hard Drive Recovery – Should We Have An External Back Up?

Technology has certainly come a long way in the past few decades. Gone are the huge contraptions that used to characterize computers. Nowadays, you can easily purchase a notebook computer that weighs in at less than 6 pounds. However, one thing hasn’t changed. Hard drives still occasionally crash and frustrated users are left trying to figure out just how to do hard drive data recovery on their own.

Hard drives aren’t perfect, although they’re amazing examples of mechanical engineering. Physical damage can easily occur since these disks are spinning at such high speeds. The smallest interference while in use can cause damage in certain areas. Various features have been put into place to reduce the likelihood of a critical hard drive failure, but these are not 100% effective. Sadly, physical damage isn’t the only reason why you may need to attempt hard drive data recovery. Many people accidentally wipe out their hard drives because they’re not sure what they’re doing.

If you do know a good deal about computers, and are not the one who messed up the hard drive in the first place, it may be possible for you to do your own hard drive data recovery. Keep in mind that to do this, you may need to fix your master boot record, or retrieve data from a physically damaged disk. If you can’t do this, then you’ll need to employ the services of a hard drive data recovery expert. Actually, if your system crashes and you don’t actually recover data for a living, I’d suggest you go straight to a hard drive data recovery expert. One thing though…they’re expensive. Come on, these guys are specialized in what they do. You didn’t really expect that any hard drive data recovery expert would do it for free, did you?

You know what can really help you save money if your hard drive does crash? Backing up your data. It seems like such a sensible thing to do, doesn’t it? Some users partition their hard drive. This makes it easy for you to do your hard drive data recovery because chances are only one partition will fail. If you’ve backed up your files, you can continue working or, better yet, you can save them to an external source and get a new hard drive. You should definitely invest in an external back up. Yes, it’s an inconvenience to remember to back up important files, but at least you won’t have to pay for a hard drive data recovery expert.

Computer Data Backups: Test Now or Cry Later

If you're like most small business owners, your computer data backups are one of those things that you rarely pay attention to. Computer data backups are kind of like flossing your teeth and eating low-fat, high-fiber foods… everyone knows what they're supposed to do… but how many REALLY do these things religiously?!?

Unfortunately when it comes to your computer data backups however, complacency can be very dangerous. Of course, it's always a good idea to have a local computer service company that you can rely on for advice on selecting and maintaining your computer data backups. But, unless you're prepared to put a full-time PC support person on your company's payroll, it's really important that you get some basic understanding of the major issues with computer data backups.

So here's a compilation of some really crucial tips on computer data backups that I've put together, after nearly 15 years of helping small businesses protect their valuable computer data files.

Test your computer data backups regularly and monitor their log files.

To be effective, computer data backups must be highly automated to ensure that jobs are launched consistently and correctly, but your computer data backup system also needs to be watched over diligently to make sure it continues to function reliably.

Unfortunately, monitoring the computer data backup system generally isn't a priority until something goes wrong. By then it's too late…. Like the article title says, “Test Now or Cry Later!”

People have a strong tendency with a computer data backup system to set it and forget it. Automation clearly has many benefits, but a totally hands-off approach can be very dangerous if no one is overseeing your computer data backup process.

Test and Then Test Again: VERY Important with Computer Data Backup Systems

With any newly installed computer data backup system, don't assume everything works correctly right out of the box. Even more important, don't take for granted that your backup system will continue working indefinitely. You need periodically to restore some folders and files from your backup media to validate that your computer data backup system still works.

If your automated computer data backup routine is configured to include a verify run with each backup job, testing a sample restore job monthly should be adequate. However, if you have an extremely low tolerance for risk, you may want to simulate a sample restore job once a week.

The Hazard of Moving Parts and Open Design with Computer Backup Systems

Why do you need to take these precautions if you're purchasing a reliable, business-class computer data backup system to start with? Typically, a tape drive or other backup device is one of the few components in a PC or server that still have moving parts.

As a result, it's more prone to mechanical failure. In addition, because a backup device generally is open, as opposed to the sealed design of a hard drive, it's easy for the inside of the computer data backup system device to attract a significant dust buildup in a relatively short period of time.

Sample Restore Jobs and Cleaning Tape Heads of Computer Data Backup Systems

Testing a tape for a sample restore job is also a great time to clean the heads of the backup drive if your backup system requires this kind of maintenance.

Restoring a few hundred megabytes (MB) of data to a scratch directory and running a head-cleaning tape should take no more than 15 to 30 minutes.

When running a test restore job, always restore the data to an alternate server folder path, so as not to disrupt the use of any shared folders.

Building a Computer System Backup and Restore Procedure Checklist
In times of crisis, the most crucial issue becomes how quickly you can get the data back onto your system, undamaged. So, as you build your computer data backup system, be sure to document your test procedures into handy checklists.

This documentation also can be great for cross-training and crucial for avoiding panic during an emergency. Be sure you have a hard copy of this documentation next to your system and stored off-site with your backup media.

Watching the Log Files of Your Computer Data Backup System

In addition to running test restore jobs, you must inspect your computer data backup system log files daily. When the backup system is first installed, take time to get familiar with the way log files look when everything is working. This way, if something goes awry, you'll be better prepared to pinpoint the nature of the problem immediately.

As network operating system (NOS) suites and backup software have become more sophisticated, it's now possible to monitor backup system log files remotely and more proactively. In most cases, the backup system log files are just plain text (.txt) files.

Many third-party tools and utilities, as well as those included with Microsoft BackOffice Small Business Server (SBS) and Microsoft BackOffice Server, can automatically e-mail or fax a backup system log file at a preconfigured time.

Automatically and Remotely Monitoring Tape Backup Log Files

Many computer consultants have their small business clients' log files automatically e-mailed to them daily, so the consultants proactively can watch out for potential problems with the computer data backup system.

However, don't think this proactive monitoring is limited to professional consultants. If your company has one or more branch offices you support from a centralized location, you also can use a similar method to monitor backup system health in remote locations.

For greater flexibility, you can set up an e-mail alias so the computer data backup system log file automatically is sent to you, your second-in-command and perhaps an external computer consultant - so you are all kept in the loop. Also, this way, monitoring continues even when you're out of the office or on vacation.

The Bottom Line

If your small business depends greatly on its computer systems, backing up your data is not optional… and it is not something that can be casually brushed to the back burner.

Use the computer data backup tips in the articles to help you become a more IT-aware small business owner. And remember, when it comes to computer data backups, "Test Now or Cry Later". The choice is yours.

Computer Backups

COMPUTERS AND HALLOWEEN, DO THEY MIX?

Computer backup is so important to your computer that to ignore it is to risk its damnation.

Computers require care and feeding. They require that you attend to their needs. If you don't, then they will most surely be sent to Hell.

Halloween means Hell. What! What do you mean that Halloween means Hell?

Well, if your computer is given the option of trick or treat, which will it accept? Will it accept the trick or the treat? What do you think?

Halloween is the time that computers are subject to tricks or treats. Did you know that more computers fail on Halloween than any other day of the year? That’s right. It’s true (smile). Your computer is in danger! Protect it. Do your computer backups.

Back to the Hell thing. Hell you say? Yep. Well, what do you mean by Hell?

Computer hell is the place for computers without computer backup. The failure to perform hard drive backup means that you are playing Russian Roulette with your data. Data needs your protection. Failure to protect your data may cause your home or business records to be sent to Hell.

Hell in this instance is for the records and files that cannot be resurrected. Resurrected you say, what does that mean?

It means that without computer backup as a source of salvation then the files can safely enjoy eternal oblivion. Oblivion you say, what does that mean? That means they are eternally lost from computer resurrection.

Is there any mercy for my precious files, you ask?

Why yes there is. Would like to know what the mercy for your files is? Yes! Yes! You say.

OK boys and girls listen carefully. The salvation, mercy, resurrection and redemption of your files lies in regular and consistent and persistent computer backup.

If you backup your computer consistently and persistently your files will be resurrected and saved from accidental deletion, hard drive failure and those nasty things like fire, flood, theft, earthquake, hurricanes, tornados and the like!

Computer backup is the key to your data's salvation!

Do your computer backups boys and girls.

Milk and cookies will be served in the pantry.

Trick or treat for your computer backup?

Companies must be prepared for data storage and backup compliance

Companies must account and deal for new legislation governing how information is stored on IT systems.

The EU is shortly to adopt many of the recommendations on corporate governance set out by the Sarbanes-Oxley Act in the US, UK firms are to be expected to deal with and manage explicit guidelines on how to store email and other documents on their IT systems. IT managers should consider the necessary procedures and technologies needed for compliance now, in order ensure technology is able to deal with the new legislation.

Regulations regarding data storage at the moment are fairly lax, but there will be a huge increase in the amount of data than must be held over the next 18 months to two years.

Email archiving, the increased use of expencive write-once read-many media, information lifecycle management and content-aware storage as a few of the technologies which firms should consider for the future, though in some cases companies will simply need to improve the way they manage existing systems.

It is anticipated that new legislations will demand that an organizations’ archiving solutions must guarantee that the information they hold has not been changed, and keep it for a specific period of time before automatically deleting it.

A survey of 493 companies in the UK has shown that compliance with regulations has a high or fairly significant impact on the data storage strategies of 87% of the organisations surveyed. Back-up and recovery was also very important to the data protection strategy of 93% of organisations.
78% of organisations future storage strategy is set to include Disk-to-Disk-to-Tape technology. This may be due to the highly affordable and flexible nature of this new technology. For example, recent deployments of disk-to-disk-to-tape (D2D2T) solutions by various companies have, on average, reduced the backup window by more than 70%, from fifteen hours to less than four, yielding significant time and cost savings in tape management.

Interestingly, product features were far more important than the brand of the product, with 82% of organisations making a decision based on product features. When it came to the decision of choosing a specialist storage supplier or a general IT provider for storage solutions there was a very slight preference for specialised storage suppliers (51%) over general IT providers (49%).

This survey shows that compliance with regulations is a key driver in companies' storage security policy and that we are likely to see more companies deploying Disk to Disk to Tape technology in the future.

All the above is fine if you are a corporate, you have an annual IT budget of ฃ500,000 and numerous members of staff who can plan and complete such a system. Is it very easy to talk about SANs, NAS’s Virtual Tape Libaries. Organisations of this nature already have a very stable and flexible infrastructure, where it is comparably easier to implement such a system.
What about the 1000’s of smaller companies such as solicitors, accountants, medical practices and manufactures etc, which may have only 2 servers on site, but still have the same reliance on data and have to adhere to the same legislations? Backup to tape is an option, however, there is an upfront cost and a requirement for a trusted member of staff to take the tapes off site every night and store in a safe place. Can you guarantee your backup has worked, and do you really trust your long term data on magnetic media? Another option is to archive your data onto optical devices, however the cost is even more prohibitive than tape and you still need to take the disk offsite.
No doubt your data is growing quickly; recently enforced legislations makes sure of this, so why not employ a backup and archival solution which has no upfront cost, is fully automated, secure and regardless of disaster will ensure your data is always available, Offsite Backup.

Compact Flash Memory and Data Recovery

Flash memory gets its name due to its microchip arrangement in such a way, that its section of memory cells gets erased in a single action or "Flash".
Both NOR and NAND Flash memory were invented by Dr. Fujio Masuoka from Toshiba in 1984.The name 'Flash' was suggested because the erasure process of the memory contents reminds a flash of a camera, and it's name was coined to express how much faster it could be erased "in a flash". Dr. Masuoka presented the invention at the International Electron Devices Meeting (IEDM) held in San Jose, California in 1984 and Intel recognizes the potentiality of the invention and introduced the first commercial NOR type flash chip in 1988, with long erase and write times.

Flash memory is a form of non-volatile memory that can be electrically erased and rewrite, which means that it does not need power to maintain the data stored in the chip. In addition, flash memory offers fast read access times and better shock resistance than hard disks. These characteristics explain the popularity of flash memory for applications such as storage on battery-powered devices.

Flash memory is advance from of EEPROM (Electrically-Erasable Programmable Read-Only Memory) that allows multiple memory locations to be erased or written in one programming operation. Unlike an EPROM (Electrically Programmable Read-Only Memory) an EEPROM can be programmed and erased multiple times electrically. Normal EEPROM only allows one location at a time to be erased or written, meaning that flash can operate at higher effective speeds when the systems using; it read and write to different locations at the same time.

Referring to the type of logic gate used in each storage cell, Flash memory is built in two varieties and named as, NOR flash and NAND flash.
Flash memory stores one bit of information in an array of transistors, called "cells", however recent flash memory devices referred as multi-level cell devices, can store more than 1 bit per cell depending on amount of electrons placed on the Floating Gate of a cell. NOR flash cell looks similar to semiconductor device like transistors, but it has two gates. First one is the control gate (CG) and the second one is a floating gate (FG) that is shield or insulated all around by an oxide layer. Because the FG is secluded by its shield oxide layer, electrons placed on it get trapped and data is stored within. On the other hand NAND Flash uses tunnel injection for writing and tunnel release for erasing.

NOR flash that was developed by Intel in 1988 with unique feature of long erase and write times and its endurance of erase cycles ranges from 10,000 to 100,000 makes it suitable for storage of program code that needs to be infrequently updated, like in digital camera and PDAs. Though, later cards demand moved towards the cheaper NAND flash; NOR-based flash is hitherto the source of all the removable media.

Followed in 1989 Samsung and Toshiba form NAND flash with higher density, lower cost per bit then NOR Flash with faster erase and write times, but it only allows sequence data access, not random like NOR Flash, which makes NAND Flash suitable for mass storage device such as memory cards. SmartMedia was first NAND-based removable media and numerous others are behind like MMC, Secure Digital, xD-Picture Cards and Memory Stick. Flash memory is frequently used to hold control code such as the basic input/output system (BIOS) in a computer. When BIOS needs to be changed (rewritten), the flash memory can be written to in block rather than byte sizes, making it simple to update.
On the other hand, flash memory is not practical to random access memory (RAM) as RAM needs to be addressable at the byte (not the block) level. Thus, it is used more as a hard drive than as a RAM. Because of this particular uniqueness, it is utilized with specifically-designed file systems which extend writes over the media and deal with the long erase times of NOR flash blocks. JFFS was the first file systems, outdated by JFFS2. Then YAFFS was released in 2003, dealing specifically with NAND flash, and JFFS2 was updated to support NAND flash too. Still, in practice most follows old FAT file system for compatibility purposes.

Although it can be read or write a byte at a time in a random access fashion, limitation of flash memory is, it must be erased a "block" at a time. Starting with a freshly erased block, any byte within that block can be programmed. However, once a byte has been programmed, it cannot be changed again until the entire block is erased. In other words, flash memory (specifically NOR flash) offers random-access read and programming operations, but cannot offer random-access rewrite or erase operations.

This effect is partially offset by some chip firmware or file system drivers by counting the writes and dynamically remapping the blocks in order to spread the write operations between the sectors, or by write verification and remapping to spare sectors in case of write failure.
Due to wear and tear on the insulating oxide layer around the charge storage mechanism, all types of flash memory erode after a certain number of erase functions ranging from 100,000 to 1,000,000, but it can be read an unlimited number of times. Flash Card is easily rewritable memory and overwrites without warning with a high probability of data being overwritten and hence lost.

In spite of all these clear advantages, worse may occur due to system failure, battery failure, accidental erasure, re-format, power surges, faulty electronics and corruption caused by hardware breakdown or software malfunctions; as a result your data could be lost and damaged.

Flash Memory Data Recovery is the process of restoring data from primary storage media when it cannot be accessed normally. Flash memory data recovery is a flash memory file recovery service that restores all corrupted and deleted photographs even if a memory card was re-formatted. This can be due to physical damage or logical damage to the storage device. Data even from damage flash memory can be recovered, and more than 90% of lost data can be restored.

Clean Room Data Recovery - What's Its Significance?

What are clean rooms? Why is clean room data recovery important? We look at these issues first.

What Are Clean Rooms?

Clean rooms are rooms that have been designed to reduce the level of particulates in the air like dust aand airborne microbes. Clean room construction employs filters extensively. Outside air is filtered to prevent dust entering the room. Filters and processes will be in place inside the room to remove internally generated contaminants during production and working areas are often further filtered locally such as laminar flow bench.

Staff would usually have to enter clean rooms through airlocks and wear protective gear while working inside the rooms.

There are different "classes" of clean rooms, with each class limiting permissible different numbers of particles per cubic meter, as well as the maximum sizes particles. Thus a Class 1 clean room is one where the number of particles should not exceed 1000 particles per cubic meter.

Clean rooms are used extensively in the pharmaceutical, semiconductor manufacturing and biotech industries. Data recovery centres typically use a Class 100 clean room that has an allowance of 100,000 particles per cubic meter (compared to 35 million particles per cubic meter in a normal room).

Why Use Clean Rooms for Data Recovery?

Clean rooms are used for data recovery to prevent dust, electro static discharges and such disturbances. These kinds of precautions become necessary because even microscopic dust particles can damage the image on the drive platters, and make data recovery difficult.

With each generation of disks, data is packed more and more densely on the disk platters. It is thus increasingly important that data recovery be attempted in exceptionally clean rooms.

Drive manufacturers usually specify that their product guarantee will become void if the drive is opened by anybody other than themselves, or their authorized agents. And typically, one of the conditions they impose on authorized agents is that the disks be opened in clean rooms meeting specified standards.

Thus clean rooms are necessary for data recovery on both performance and product warranty considerations.

Clean Room Data Recovery

Disk drives are opened only in clean rooms and kept there until the recovery is complete and the drive is closed. All devices are also protected against electro-static discharge, physical shocks, temperature fluctuations and electrical disturbances.

Staff wear special clothing while working in the rooms and particle density is constantly monitored using particle counters. A typical objective of clean room data recovery centers is to maintain Class 10 conditions during production.

Conclusion

Data storage media are getting packed with data more and more densely with each new generation of drives. It is thus extremely important to attempt data recovery in exceptionally dust free rooms.

These days, clean room data recovery uses Class 100 clean rooms where the number of particles is reduced by some 350 times compared to normally prevailing particle density.

Clean room data recovery centers actually aim to achieve even higher levels of dust free conditions during production operations. Even minute specks of dust on the drive platters can damage the image on the media, and make data recovery even more difficult, if not impossible.

Can USB Data Recovery Be Recovered?

When you store important information on a USB device, you take the chance of losing that information. Losing data on a USB can be kind of a mystery, but there are companies out there that can help you get that data back. These companies use engineering that can recover your lost data over ninety six percent of the time. These companies can even recover data that has been stored on a damaged USB device. So when you find yourself in a situation where you have lost valuable information you should not assume that this data can not be retrieved.

A Safer Way to Recover Damaged Partitions

Repairing damaged partitions on is a risky business. Even if you use the best toolkit and are absolutely sure in what you are doing, you are still risking your files shall something go wrong. Changes made to the damaged partition are irreversible; it is just too easy to overwrite an important system structure that holds vital information about your disk, files and data. Bottom line: it's good to backup before performing data recovery. But is this really the best way to do it?

There is a different approach to do data recovery that is even safer. No need to backup and restore during the recovery. Instead of making a backup copy of corrupted data, you can simply take a binary snapshot of the partition being repaired, and attempt the recovery with different settings as many times as you need on this snapshot instead of the actual disk.

SoftAmbulance Partition Doctor by http://softambulance.com/ is one of a few data recovery tools that allow recovering a virtual image of a damaged hard drive instead of repairing the hard drive directly. The data recovery tool lets you create a binary image of the damaged hard drive, and works with the binary image instead of the real thing. The binary image is a big file stored on another hard disk, CD, DVD or other media. The technology is similar to making an .iso image of a CD or DVD disc, only SoftAmbulance Partition Doctor extends it to partitions or even entire disks.

The hard drive copy may be virtual, but any data you save from it is for real. SoftAmbulance Partition Doctor can recover your files, documents and other data from the binary image and put it on a healthy media. After that, you can attempt fixing the damaged system structures of the corrupted hard drivewithout taking any risk at all. Any modifications will be performed on the virtual image.

Don't rush the recovery. Don't take the risk of losing or corrupting your data. Create a virtual snapshot of the hard drive being repaired, and work on that snapshot instead of accessing the corrupted hard drive. This procedure keeps your original data safe, and ensures the highest level of safety during the recovery process.

SoftAmbulance Partition Doctor recovers files from damaged and corrupted disks and partitions and fixes damaged hard drives. The disk recovery product supports all 32-bit versions of Windows, and recovers FAT and NTFS formatted hard disks, memory cards, CD and DVD media, and USB flash drives.

5 Steps to Securing Your Windows XP Home Computer

Most people are aware that there are continuous security issues with Microsoft’s Windows operating system and other programs. However, what most people do not realize is how easy it is to significantly improve your computer’s security and reduce the likelihood of becoming a victim to ever increasingly sophisticated threats that lurk on the internet. These steps should take less than a couple of hours to complete and should not clean out your wallet.

1) Windows Update – the first crucial step you need to take to make sure that all your Microsoft applications have all the latest product updates installed. These updates or “patches” address security vulnerabilities and other issues. Microsoft usually issues these updates on a monthly cycle. Visit the Microsoft website or switch on automatic updates from the Windows Control panel. Even if your “new” computer is second hand this is still a critical first step. If you buy a used computer with Windows XP make sure Service Pack 2 or SP2 is installed.

2) Strong Passwords - people often overlook this but having well thought through passwords is an important element of your computer security. A strong password should include at least 8 characters with a mixture of text, symbols and numbers. As a minimum you need to make sure the services most at risk have a strong log-in password. These services include your bank, credit card, other financial services like PayPal, your email address and any other services like Ebay which hackers can use to generate profit.

3) Anti Virus Protection – while it is fair to say the threat of the computer virus has receded during the last couple of years they can still inflict serious damage on your computer. Part of the reason why the threat has reduced is because PC manufactures are now more frequently bundling anti virus packages with their new computers. For example last year my new Dell shipped with a 90-day trial of McAfee's Internet Security Suite. The best bet here is to purchase a security package which includes firewall and anti virus software as a minimum. Top brands include McAfee and Symantec Norton products. However, Microsoft has recently entered the market with their "OneCare" offering which is very aggressively priced.

4) Firewall - if you are using a broadband connection then a firewall is definite requirement to manage the traffic flowing between your computer and the internet. A firewall monitors the inbound internet traffic passing through the ports of your computer. Better products also monitor outbound traffic from your computer to the internet. As per above the best bet here is buy a firewall application as part of a security package which most vendors offer as standard. If a hardware firewall is included as part of your router package then you do not need anything else. A company called Zone Labs offer a great free firewall product called Zone Alarm which should be used as a minimum. Windows XP does now ship with a free firewall but the product does not monitor outbound communication and therefore I believe does not offer adequate protection.

5) Anti Spyware Tool - this software is the last piece in your basic internet security set up. This tool helps combat spyware and adware. There is a good mixture of free and paid versions on offer. Good free software include Microsoft's Windows Defender, Spybot S&D or Ewido Anti-Malware. Ewido Anti-Malware is frequently recommended in computer help forums. Be careful if you decide to purchase a solution. There are a number of rogue vendors out there which aggressively push products which offer you little value. Stick to trusted names like Webroot's Spy Sweeper or PC Tool's Spyware Doctor. These products always come out well on independent tests.
