Backup and Recovery

Backup and recovery is the process of creating copies of data (backups) so that it can be restored or recovered to a previous state if the original data is lost or corrupted.

Who uses backup and recovery, and why?

Enterprises of all sizes rely on backup and recovery to maintain business continuity. In the event that their business data is lost, they can get back up and running by restoring data from a backup copy.

Government regulations require companies to store and archive electronic records without alteration. A backup and recovery process also enables enterprises to maintain legal and regulatory compliance.

How backup and recovery works

Companies try to back up their data on a regular schedule such as once every 24 hours. At these times they create one or more duplicate or deduplicated copies of the primary data and write it to a new disk or to a tape.

For disaster recovery purposes, a backup copy needs to be transported or replicated offsite to ensure the data is safe in the event of a disaster.

Benefits of backup and recovery

Backup and recovery enables companies to protect and preserve their information.

Information protection is critical to a company's day-to-day operations. In the digital age, information is one of the most important assets a company owns, and having an efficient and manageable backup and recovery strategy has become an IT imperative.
