Tape Data Recovery Software
Wednesday, July 29, 2009

Tapes are used to store large amount of data, but the tape media can get corrupt due to unknown reasons. The inaccessible data is then recovered through Physical and Logical data recovery techniques.

Tape drives are installed in the cleanest environment and require high quality, cleaning on a regular basis, and proper handling of the tape media. Improper or poor usage, handling, and storing of tape drives lead to tape drive corruptions or damages.

Tape drives are developed to be operated in clean environment; dust particles, fibers and airborne particles can cause damage to the tape drive. The tape drives need clean environment because when a tape is installed to a tape drive, the clearance between the heads and the tape is measured in microns thus the particles can damage the tape or the head if they come in contact with either.

The tape drive is generally used to save and restore system data files, to archive important records and to distribute operating system software upgrades. The needs are great but also are the consequences. Tape media can get damage or corrupt due to mishandling, improper usage, damaged tape headers, erased tape drives, broken or de-spooled backup tapes, failed backup systems and tape libraries, unexpected system shutdowns or system failures.

In this scenario, tape data recovery proves effective and user can always get back the lost data. There are two primary tape data recovery procedures ? Physical and Logical.

Physical data recovery comes into existence when there is physical problem with the tape media. This type of data recovery includes dealing with deteriorating magnetic coatings, broken tapes, twisted or folded tapes, cracked or sealed cartridges and also the tape media affected due to fire, water, mud, debris etc.

Logical data recovery is the most difficult and expensive data recovery process. This process includes recovery of files logically from the tape drives. Data which was successfully recorded on the media but now cannot be read for unknown reasons is recovered. This type of data recovery involves usage of tape recovery software. The tape data recovery software effectively restores and recovers the lost and inaccessible files and folders.

The tape recovery utilities like Kernel tape recovery software effectively recovers missing, lost, deleted file (s) and folder (s) from all types of corrupt, damaged tapes like DLT, LTO, AIT, DAT and every other tape media type.

Data Backup And Recovery Processes
Wednesday, July 22, 2009

You need to know an awful lot when it comes to computers and computer systems, one of the most important is the matter of data backup and recovery.

You need data backup and recovery processes in case something happens to your computer, in case it shuts itself off suddenly or in case it becomes corrupted. You need to know that your files and information are safe and are not going to be deleted, but rather put into a data backup and recovery partition so that you can retrieve them later if you ever need to.

More info about Data Backup and Recovery

Just make sure you save your data as many times as you can, just in case the files you are working on do get deleted and you can't go back to them, and in case the data recovery files that work on your computer can't save them. Make sure that you take as many precautions as you can, to be safe, but try to be aware that if you do have proper data recovery processes on your computer, then you can stop worrying.

Also, try to make sure that you upgrade your data backup services in your computer whenever you need to and whenever you can. If you aren't sure if you've got any data recovery software on your computer, or if you know that you have and want to know if it can be upgraded, the best thing for you to do is to take your computer into a professional so that they can tell you whether or not you can or need to upgrade.

Or, the alternative would be to get someone in to your place of work to say if you can be upgraded or not. Once you have determined if you need to or not, you can then work out what type of system you should upgrade to. Ask the right people so that you can learn what you need to before making any decisions, try with the guy who told you to upgrade. The type of data backup software will totally depend on what you are trying to backup, and how quickly you will need to recover the data, just make sure that you are buying what you need and don't end up pruchasing things that you don't need to.

Do your own research, this way you will truly learn as much as possible, because you want the make sure that you are as knowledgeable as possible in order that you get the best results possible from your purchase.

RAID Data Recovery - How It Works
Tuesday, July 14, 2009

RAID data recovery is probably one of the most complex processes any data recovery firm can perform. More often than not, the problems are compounded by the actions of the client prior to sending the drives in for recovery. Many users feel that it is important to try and recover the data themselves or repair the array through various system utilities, and this may be fine if the data is not critical. However, it has been our experience that when you have a RAID failure that has resulted in substantial data loss, more often than not, somebody's job is on the line if that data is not recovered. The biggest piece of advise this article can provide in the event of a RAID failure: LEAVE IT ALONE.

IT professionals have a lot of pressure placed on them when a catastrophic system failure occurs. It is their job to make sure that all systems are up and running. Many times, out of panic, troubleshooting processes are initiated in order to correct the problem. Often times these processes only make a bad situation even worse, and in many instances they can render the data unrecoverable. Let's keep in mind what this data can consist of in an average corporate environment. You are probably dealing with information that cost many hundreds of thousands of dollars in labor and resources to create. Much of the data probably can't be duplicated. The intellectual value alone could be in the many millions of dollars. Corporate executives really don't care to hear about how the failure occurred, or what unbelievable string of events led up to the server crashing. They don't care to hear the technical jargon as you try to explain to them what happened, and hope they understand that it wasn't your fault. They only want to know one thing..."why was this data not backed up, and how can we get it back?"

Instead of taking chances on your own, call a data recovery professional. RAID data recovery can be expensive, but in most cases it is much less costly than trying to recreate the data that has been lost. There is a set procedure that most data recovery professionals follow when it comes to performing any recovery work. These procedures are followed and expanded upon when dealing with a RAID recovery. The first step of any RAID recovery is to make sure all of the drives are functional. In order to properly complete the recovery it is essential that all drives are fully functional (this is especially true with a RAID 0). This may involve taking any physically damaged drives into the clean room, in order to make the necessary repairs so that they function normally again. Once that is completed the next step is to make complete, sector-by-sector clones of every drive. This is not "Ghosting", but a very low-level process that allows the recovery technician to work around bad sectors, and have complete control over how the drive functions. During the cloning process, the original source drive that you sent in, is generally put in a "write protect" mode so that no data can be written to the drive. This insures that the original source data is not altered in any way.

Once the cloning process is complete, the original drives you sent in are set off to the side and are no longer touched. The actual recovery process is performed on the cloned copies, so nothing that is done during recovery can make the situation worse. After the drives are cloned, they will be loaded into an emmulator and destriped. Destriping is like taking the scattered pieces of a puzzle and putting them together neatly. Simply stated, destriping is taking the data scattered among the multiple drives that make up array and placing it onto a single destination drive. From there we have a single drive in which we can complete what we would consider to be a "normal" recovery. We can complete this process even at the multi-terrabyte level. If the damage to the stripe is not too severe, in most cases a complete rebuild of the directory structure and all associated data can be completed.

As mentioned earlier, RAID data recovery can be expensive. Depending on the company you contact the prices can vary considerably. Typically a RAID recovery can be priced anywhere from $800 to $3,000 per drive. A number of factors influence the cost, such as RAID type, file system, total size, situation of failure, etc. Many times attempt fees and evaluation fees are charged if the data is unrecoverable. This is understandable due to the amount of time and resources required to perform a single RAID recovery. However, in most cases the costs involved in recovering the data are not even 1% of the data's overall value. If you are reading this article and you haven't suffered a RAID failure, what are you waiting for? Back up your data NOW.

Hard Drive Data Recovery Doesn't Need To Be Hard
Monday, July 6, 2009

Hard drive data recovery can be a difficult topic for many new computer users. No one wants to believe that their data is lost, and most people have no idea how to get it back. Fortunately, there are data recovery services available that can help you with the overwhelming task of recovering your lost data. This article is intended to help you learn more about hard drive data recovery and how you can learn more.

A hard drive is a "non-volatile" storage space designed to hold data. The data is stored on a magnetic surface which is called a hard disk platter. There are many reasons why data can be lost from the hard drive, including the mechanics of the hard drive itself, and external problems. Most hard drives today have several moving parts which need to be carefully synchronized in order to maintain a constant spin rate, called RPM, inside your computer.

Modern hard drives have "SMART" technology, which stands for "self-monitoring, analysis, and reporting technology." All that means is that the computer will diagnose itself and be able to solve the majority of its problems, also that it corrects the motors and fans when needed, and lets you deal with using the computer instead of trying to maintain it.

In order to understand hard drive data recovery, it is essential to understand how data is lost from a hard drive. Let's define data loss as an unforeseen loss of data or information previously stored on your hard drive. Murphy's Law demonstrates only when it's too late that we should have been backing up our hard drive better. The best way to recover data is to never lose it in the first place, but that is a topic for a different article.

Data can be lost during a power failure, because there is unsaved data in the memory which is not yet been saved to the hard drive. Data can also be lost through a disk failure which can happen for a number of reasons, usually mechanical such as a crash in the hard drive machinery itself. Software can also crash on your computer, especially if you are using Microsoft products, and could lead to a loss of data on your hard drive. Viruses or other malicious software can corrupt your data and is one of the biggest reasons for data loss. Fortunately, today's technology provides a pretty good track record on recovering data from your hard drive.

The best thing to do is to look in your phone book or on the Internet for a local hard drive data recovery specialist. These are people who have been trained or have experience in recovering lost data and can be your best friends-especially in an emergency situation. There are many who specialize in hard drive data recovery and are happy to help you with your data recovery problems. The price they charge is normally a small price to pay if the alternative is losing your data forever.
