What term refers to a copy of data kept for recovery after data loss or system failure?

Explanation:
Preserving data so you can recover after loss or a system failure is accomplished with a backup. A backup is a duplicate of data stored separately from the primary system, kept specifically for restoration when the original data is lost or corrupted. Backups can be full or incremental/differential, designed to balance how quickly you can recover with how much storage is used, and they support restoring to a known good state at a chosen point in time. The other terms don’t fit: an asset is anything valuable owned or managed, attenuation is signal loss, and authentication is verifying someone’s identity.
