KembaraXtra-Computer Terms – backup and recovery:
Backup and recovery is a strategy used in database management systems to restore a database to a consistent and usable state after it has been affected by a system failure, software error, or hardware malfunction. The process begins by restoring the most recent backup copy of the database. After the backup is restored, the system reads the transaction log or change file that records all database operations performed since the backup was created. By replaying these logged transactions up to the most recent checkpoint, the system reconstructs the database so that it reflects the latest complete and consistent state before the failure occurred.
