backuprollbackmekanismer
Backup and rollback mechanisms, often referred to in some discussions as backuprollbackmekanismer, are techniques used to recover data and restore system state after failures, errors, or corruption. Backups create copies of data at known points in time, while rollback mechanisms rewind or undo changes to a previous consistent state. Together, they support availability, data integrity, and fault tolerance in databases, file systems, and application services.
Backup mechanisms include full backups, incremental, differential backups, snapshots, and continuous data protection. Full backups copy
Rollback mechanisms cover how to revert to a prior state within or across transactions. Transaction logs, undo
Implementation considerations include recovery time objective (RTO) and recovery point objective (RPO), storage costs, and performance
Best practices emphasize regular testing of restore procedures, clearly defined retention, immutable backups where possible, encryption,
