Recovering data from raid systems
By Jakob Jelling
Raid (Redundant Array of Inexpensive Disks) is a method of storing and processing data that assimilates several hard drives into one logical unit. The method allows for sharing of data from multiple hard drives. There are several benefits to this method such as increased availability of information and faster speeds of data access.
However when a data loss occurs due to events such as a deadly virus, the amount of data lost and the significance of the data lost can be immense to companies and firms. Raid systems can form complex networks. They are not immune to failure and accidental loss of data and system failures can plague raid systems also.
Data can be lost when raid arrays are damaged and the data made inaccessible. A failure of the raid array system can cause failures in multiple drives. Raid data recovery is therefore also a complex operation.
Raid data recovery can often work where other data recovery operations have failed. Raid data recovery operations can work on various systems varying from Raid 0 to Raid 5 and other raid systems.
A data recovery operation from a professional firm can entail the following process:
Often raid data recovery operations have to be performed in a short time limit to alleviate the damages from loss of important data. Data is being stored in mass quantities by firms. The data is often critical to the smooth running of the firm. Many firms cannot fathom losing data such as their customer database, which would make them unable to reach any customers, or their dealer contacts which can entail losing a lot of hours in recompiling the list.
Data recovery services can perform raid operations. Many firms have a team of specialists to perform the job. First they evaluate the extent of damage done and map out the process to recovery.
Professional and high quality data recovery services can come with a hefty cost.
The companies often have special software tools on hand to help them perform the job. The software specialists usually have lots of knowledge about recovery operations and can safely reconstruct the data from damaged hard drives. The data can then be returned to customers in a format they prefer.
Only attempt a recovery operation or fixing the error in your computer, by opening up the hard drive, if you are experienced in computer technology and are confident you can complete the process without any mistakes. Your recovery operation may be costlier if you tamper with the machine yourself before taking it to professional firms.
Raid systems often contain the lifeblood of a small firm. Without the data the firm operations can essentially shut down. Raid systems can also fail in big corporations. So if you have accidentally deleted a 500 page essay, you can stop feeling sheepish.
Raid systems are built to be highly fault tolerant, however their internal mechanism is still susceptible to failure. Also data might be lost through the actions of an inexperienced user, which is harder for managers to prevent. Whatever the data you need recovered such as databases, user directories, and important files, data recovery operations can retrieve it for you.
