What Is Data Recovery And Why Does It Matter To You?

To be precise, the phrase ?data recovery? refers to the process whereby data is saved from storage media that has either been corrupted, damaged, failed, or made inaccessible for some reason. When data cannot be accessed the way it normally is, then we have to seek ways to recover it. This also happens to such entities as hard disk drives on computers, compact discs, DVDs, RAID, storage tapes, and other forms of electronics.

Data loss typically comes about as a result of either physical damage to the device storing the data or else logical damage done to the device?s file storage system. The latter type of damage results in the data being unable to be mounted by the host?s operating system.

The term ?data recovery? might also refer to the process whereby information that has been deleted is retrieved and secured from a storage system for forensic purposes.

Physical damage can afflict storage media in a variety of fashions. For one thing, a compact disc storing pertinent data can be affected by having one of its layers or its metallic substrate scraped off of it. Hard drive disks often experience mechanical failures, such as failed motors or head crashes. Quite often, tapes simply break down.

The problem with physical damage is that it always causes the loss of at least some ? if not all data on the storage device. Sometimes the system?s logical structures can be seriously damaged as well. Logical damage must be dealt with immediately in order for any data recovery to occur.

It is much more common for logical damage to occur than physical damage. Most of the time, logical damage comes about as the result of a power outage, which will prevent the structures of the file system from being written to the desired storage media. As a result, the file system remains inconsistent. If your system is behaving in a strange fashion or crashes, you might lose some pertinent data that will have to be recovered. Thankfully, it is much easier to do this when it is a case of logical damage, rather than physical damage.

Data Loss & Recovery

On Tuesday March 20th, 2007, the Associated Press reported a computer tech wiped out $38 billion dollars of account data for Alaska's Department of Revenue. The article reported that it would cost about $200,000 to re-key the data from their paper backups in over 300 boxes. This story is not uncommon, and data loss could cost more: it can put you out of business. For most home users, data loss means lousing address books, pictures, memories, resumes, check books, and music. While this probably is not catastrophic, some can never be recreated. For a business though, their data makes them more efficient: pulling something up in the computer and not having to pull a paper file. For some businesses, this data is critical. To determine how critical your data is, go a month without using is: do not open any existing documents, no computerized accounting, don't think about sending an email using your address book, and do not use Outlook in general. When your data is gone, it has gone to digital "La-La Land" to never return.

The Value of Data

When considering the value of your data, we have two routes: data recovery, and data re-creation. Data recovery for a single drive may cost from $750 - $3,500. A stripped RAID array with parity (RAID 3) would cost from $2,250 to $10,500. If data recovery is possibly, it might be worth considering.

The other method to recover data is to re-enter the data. This value could be determined by the amount you would pay staff to enter data. The quicker you need it, the more costly - over-time. Consider a company who louses a year of accounting data. The accounting department consists of 4 fulltime employees making $14 an hour. The cost to recreate this data would be approximately $112,000.

These estimates are for data that can be recovered. Sometimes data recovery is not an option, and the data is lost. Unlike on the TV series CSI and 24, data is not always recoverable. In preparation for this type of disaster, you might consider what data cannot be recreated, or the cost to recreate exceeds your means. Backing up data is not just important, but critical. The cost to recreate the data, the time required recreating data, and the loss to efficiency can strangle an organization.

Considering the cost to get your data back, you should be prepared to lose it. Backup any data you cannot go without. In all likelihood, these backups will be the difference between having this data, and having to go without this data.

Data Recovery And File Recovery Tools

Data recovery is used when serious situations and accidents occur to your system, like when hard drives has been formatted, or if you accidentally delete a file that you really need, which is no impossible, or it can also be used when a virus enters your system and deletes some of your files and information. The great thing is that any data recovery software works sufficiently with most computers and operating systems.

You can use data recovery software to recover information from your local hard drive, your extra hard drive, a floppy disk, a removable or portable hard drive, memory cards, and in most cases you could even use it to recover information from old CD?s. In addition a hard drive crash is no match for data recovery software. The other great thing is that you will be able to recover basically every piece of information that was on you hard drive like your email messages, video files, music and photos and obviously your data files and documents.

There are two main ways of retrieving lost data using a data recovery software, one being when the file you are retrieving has been recently deleted, the other option is to recover everything that has been on the hard disk and from there you find what you are looking for.

There are many different data recovery software programs you can use to recover your files; some of them even let you browse through your deleted files to see what you would like to retrieve. There are processes that can recover and restore your deleted files in seconds! Once the data has been recovered from you hard drive you have the option to either save it to another folder on a different hard drive or storage device, or you can burn it directly to CD. Once your files have been successfully recovered by the data recovery software, all your information stays the same, which is to say that nothing will have been changed, even in the event of a virus overload, the file names and all the date will still be in tact.

Your lost files can be restored in one click and they can be stored by name, size or date of saving. A search session also gets saved to a disk file that is used later for reloading so that the drive will not need to be scanned again, which makes the restoration process so much easier and quicker.

Majority of the data recovery software programs are offered as free demo version. You can easily download the software from the internet and try how it works.

Good Things To Know About Raid Data Recovery

When it comes to the recovery of data from a hard disk, the best option for any firm is to use the Raid data recovery method. It is a very complex process that tries to repair the damage done by the client before sending the hard disk to the data recovery firm. It is never advisable for a user to try and recover the data himself. These clients may use certain system utilities tools in order to repair the array, but they may very often cause even more trouble. And, as when things go bad, they usually do when the data is critical, these hard disks should be directly taken to a firm that is specialized in data recovery. For example, previous happenings have showed that, when a RAID failure occurs and results in the loss of important data, somebody?s job is on the line! If the data is not recovered, then things get quite complicated, for the employee, as well as for the employer.

Therefore, the best action you can take in the situation of a Raid data recovery problem is to immediately send the hard disk to a specialized firm. Should a serious system failure occur, the whole pressure is transferred to the hard disk data recovery professionals. As the users are in the habit of starting troubleshooting processes in order to solve the problem, the data recovery experts must also repair the damage done by these processes, as they can make the data impossible to recover. The information involved in such a situation can cost many hundreds of thousands, possibly millions of dollars in labor and resources to create. This is the reason why the executives are not at all interested in finding out the cause of the failure, they just care about the fact that the server has crashed and that the problem must be immediately solved.

It is true that the Raid data recovery process can be pretty expensive, but in most cases it is nothing compared to trying to recreate the data that has been destroyed. Not to speak about the fact that getting the data back could be enough to save someone's job!

The procedures that Raid data recovery consists of start by making sure all of the drives are properly functioning. This may mean taking the physically damaged drives into the clean room and try to make all the necessary repairs, in order for them to normally function again. The hard disk data recovery technician then initiates a very low-level process that allows him to work around bad sectors of the disk. It is in fact making complete sector-by-sector clones of every drive. The original source drive is being put in a "write protect" mode, in order to protect the existing data during the cloning process. The actual recovery process is performed on these cloned copies!

There are many elements that dictate the high price of the Raid data recovery process: the file system, the total size of the damaged drives and the situation of failure. Therefore, the best thing you can do is avoid the damage and a job loss by backing up your data!

Secure Data Backup And Instant File Recovery

Just how recoverable are your computer files?

There are many times when the PC seems to ?have it in for you?. I have even known servers with really nasty streaks ? how is this for an example:

I was running an IT training course in a secure establishment. The day before, I set everything up with a technician, had it checked and locked the room.

The next day the network would not work and when it did all the files for the course were missing. It took us a day to put everything back together and then do a tape backup - all for a two day course.

The next two days were perfect, but that was a training course, Imagine if that had been your small business computer or home machine and you were off to see a client.

What are the options to secure Data

It is estimated that 80% of small business could go out of business if their PC's fail so we have all learned to back up our work and know that tomorrow everything will be OK... YOU DO BACK UP DON?T YOU????

When you need to restore data

What happens if the file you need for your presentation has GONE. No, I mean it - GONE! It may have been deleted and then the Recycle Bin emptied. It may have been too big for the recycle bin and so your back-up was not there.

Well you do what I have done, you go into the meeting or training session with no notes or no presentation and you 'busk it'. It looks bad and it is bad. If you are in a large corporation and this is an important presentation, the technicians will beaver away on your PC or server area trying to get the files back in a usable form. They will probably succeed but it can take days if they are trying to recover from a tape backup. Luckily many have software that will do the job.

If you are a sole trader or a small company - welcome to the world of terror.

If your file does get deleted and has not been backed-up what can you do?

Having been working via the Internet as a small business owner for nearly 20 years I have kept up with all the products for backing-up, saving and those that can search, find and retrieve lost files.

The only problem is that with some programmes you have to actually have the programme on your PC when you need it.

What should you do to prepare for the worst?

For small business owners, File recovery and data safety come down to the following:

1 Backup weekly to removable storage such as CD, DVD, ZIP or an Internet data backup provider. If you store the data on your own media remove the backup media from the premises ? say from office to home. At least in that way file recovery can be achieved if something happens to the main office.

2 Backup important daily work onto another machine if you have one, or CD/DVD.

3 If you lose today?s work - there is only one solution and that is search the net, find an instant file recovery product, download it and find that file. Better still, have the software ready loaded. I have used quite a few data recovery programs and find that Instant File Recovery gives a good result when needed. It is also cost effective.

What irreplaceable material is on your computer?

If you don?t want to lose it, safeguard it now.

Make sure you have all the backups that you need and software that will allow you to recover any lost or missing files.

All computers die at some point; BE READY for when it happens.

Data Recovery, Backup, Restoration, and Disaster Recovery - Definitions Merge

Over the past several years there has been a confluence of the definitions of Data Recovery, Data Backup and Restoration, and Disaster Recovery. The merging of these definitions does not serve the industry. It only serves to confuse the consumer, the very people these various industry segments want to reach.

Data Recovery
Defined as the process of extracting data from inaccessible storage media or storage system such as hard drives, tapes, optical media and RAID's. The process involves repairing physical damage, repairing electrical damage, correcting media maintenance information, correcting data corruption, undeleting files or some combination thereof.

Data Backup and Restoration
This process begins with an intentional effort to store data on alternate media such as tape, optical media, hard drives, other storage systems or an online service. That's the Backup portion. In the event of a failure of the primary storage media, the alternate media is used to restore data from the alternate source to a new primary source. That's the Restoration segment.

Disaster Recovery
The process of returning an entity, such as a business or home office, to a functional and optimal state after a natural disaster or man-made event that either completely or partially impairs the function of that entity. Disaster recovery may include data recovery and/or data backup and restoration.

There are key differences that make these definitions and industries unique. Data Recovery is usually considered after data restoration has been eliminated as an option. Data backup and restoration is considered a primary function of computing to ensure data is safe from media failures. Disaster Recovery takes into consideration the complete infrastructure including facility restoration, data restoration and data recovery as a last resort.

In a literal sense there is an intentional effort to ?recover? data from some sort of catastrophic event in all three environments. That may be the source for the merging of these terms.

Confusing the consumer is not the only effect of this merging or confluence. Do a search in Google News for ?Data Recovery?. You'll find results appear for all three definitions on the first page. In the future, this confluence may make it difficult for the search engines to discern between the three. Will this effect snowball? Only time will tell.

While some businesses offer services and products that address all three categories, the definitions need to be clearly defined. As there is no unifying body or advocacy group for any of these industry segments it's likely the definitions will continue to be fuzzy at the very least. Until these definitions are more clearly defined, it will be up to the consumer to determine what Data Recovery really means.

Understanding Data Loss and Data Recovery

Losing data is the worst thing that can happen to someone who is too attached to computers. It is not a question on "how attached" a person is, it is a question on how much a person earns out of his data. In other words, for beginner computer users, losing files is like losing common documents, but for developers, it means losing source files. Source files are projects developed with the use of certain complex application. Losing them is close to losing a career!

Data recovery is the solution to lost files. Data do not just disappear in one click but some of them are stored and could be recovered. The means of data recovery depends on the diagnostic and troubleshooting on how the functioning of the computer started.

It is not easy to determine problems in the computer for a novice, but for experts, events with PC sounds, speed change, temperature and booting problems are just some signs and symptoms of a lingering problems which could lead to data loss. Corrupt files occur when there is direct disturbance changing the data properties. When a project file can't be opened, it is possibly corrupt. Latest softwares have the capability to recover files in one execution.

Simple documents have high potential possibility of destruction. Complex applications involving vectors with larger project files, when corrupted, have the least chance of recovery. Examples of which are computer aided design applications, graphic arts editor, video editors and programming applications.

What are the kinds of flaws that trigger data loss?

Physical Defect Of Peripherals - hard disk damages show signs of file corruption before affecting the raw data. Upon knowing the sign of hard disk failure, it is important to make back-ups to avoid losing current and past data. Accidents and unavoidable circumstances can also cause peripheral damages in a PC, which can lead to data loss.

Overheating of the CPU can lead to chain reaction and shut of the computer. Constant crashing without proper shutting down procedure is one of the harshest of data destroyer. Usually the current file being worked on before the big crash happened is the one rendered useless afterwards.

Virus Attack - computer intruders will not give computers any benefit. Virus is always created to destroy data. By installing an effective anti-virus, this problem can be avoided or can be resolved easier than not having one. Careless downloading of any freebies in the Internet is harmful. It is important to understand how adwares can harm your local file in just one click. Virus propagators in the net are using advertising tools to gain access remotely to any private data.

On the onset of viral attack, do not do anything in the computer or leave it on any further. The more it is left functioning, the more the virus will spread and destroy the system. If you suspect your PC has been attacked, give it an instant cold boot. Do not use it unless the purpose is data recovery and diagnostics.

Accidental Format - A person could be too drunk booting the PC and accidentally executing the format command! Formatting is the greatest mortal sin one can execute to a disk rich with important data. It is the last resort when a disk has too many garbage needing a good overhaul. Formatting a disk is erasing the entire disk for good. Some good utilities have means to UNFORMAT and regain back the lost data in a formatted hard disk.
