What is Backup Strategy?
Turkish: Yedekleme Stratejisi (Backup)
A backup strategy defines how often, where, and how data is copied so teams can recover from outages, mistakes, or attacks.
What is Backup Strategy?
A backup strategy is not just about taking copies. It defines which data can be recovered, how much data loss is acceptable, and how long recovery may take. For that reason, backup design is a core input to a disaster recovery plan.
Two metrics are especially important: RPO describes acceptable data loss, while RTO describes acceptable recovery time. Accounting data may need an RPO of minutes, while archived reports may tolerate daily backups. If targets are not based on business impact, backups can become either unnecessarily expensive or insufficiently protective.
Backup Types
Full backups, incremental backups, differential backups, snapshots, database dumps, and object storage versioning serve different needs. Replication improves availability, but it is not always a backup. Accidentally deleted or corrupted data can quickly replicate to other copies.
Against ransomware, at least some backups should be immutable, offline, or stored in a separate trust boundary. The most important control is restore testing. An untested backup is only an assumption during a crisis; regular restore drills reveal timing, missing dependencies, and permission problems.
