No business wants to perform a data recovery operation, particularly a massive one; but every business needs to be prepared in case data recovery becomes necessary. Data recovery refers to processes that are used to salvage information from secondary storage devices when that information has somehow become damaged or been rendered inaccessible. In some cases, the data itself may actually not be destroyed at all, but it cannot be loaded into the computer's memory arrays because of damage to the operating system or the file system that the system uses to organize access to data.
Secondary storage devices can benefit from data recovery, including not just traditional internal and external hard drives, but also other hardware devices including USB flash or thumb drives, solid state drives, CD disks, DVD disks, storage tapes, and RAID (redundant arrays of independent disks), a storage strategy in which several disk drives are cobbled together into a single logical unit.
With coordinated backup programs and other IT solutions, companies and other organizations can ensure that they have a continuously updated backup copy of all-important data. This type of approach is best implemented through a managed services model for IT support since in that model, ongoing on-site support will help to guarantee that all backup systems are continuing to do their job faultlessly. Businesses that proactively plan in this manner can simply access the data needed from a backup copy, an operation that may go most smoothly if done when managed programs personnel are on hand to shepherd it to a successful completion.
In cases where true data recovery becomes necessary, businesses can avail themselves of several strategies depending on the exact cause of the data failure. When the data loss has been caused by a disk failure, it may be difficult to read the information needed. In these cases, managed programs staff may be able to provide IT services such as a repair of the file system or master boot record. Software-reliant recovery of data that has become corrupted is also sometimes possible.
In all cases, however, it is better to avoid the need for data recovery by using robust and well-maintained backup systems and software.
