Data protection is the process of safeguarding important information from corruption and/or loss.
The term data protection is used to describe both operational backup of data and disaster recovery/business continuity (BC/DR). A data protection strategy should include data lifecycle management (DLM), a process that automates the movement of critical data to online and offline storage and information lifecycle management (ILM), a comprehensive strategy for valuing, cataloging and protecting information assets from application/user errors, malware/virus attacks, machine failure or facility outages/disruptions.
Storage technologies that can be used to protect data include tape backup, which copies designated information to a tape cartridge device so it can be safely stored and mirroring, which creates an exact replica of a website or files so they are available from more than one place. Storage snapshots can automatically generate a set of pointers to information stored on tape or disk, allowing for faster data recovery, while continuous data protection (CDP) backs up all the data in an enterprise whenever a change is made.
