Copying data to a separate location to enable recovery in case of data loss, corruption, or disaster.
Backup is the process of copying data to a separate location—local storage, offsite facility, or cloud—to enable recovery when the original data is lost, corrupted, or inaccessible. Effective backup requires understanding what data matters, how quickly it must be recovered, and how much data loss is acceptable. Modern backup addresses not just hardware failures but ransomware, accidental deletion, and disasters. Backup is your last line of defence when everything else fails.
Why It Matters
The DSC Perspective:
Backup is your insurance policy. When ransomware encrypts your data or hardware fails, backup enables recovery. Without tested backups, a single incident can destroy your business.
