Snapshot versus backup
A cloud server snapshot is a fast point-in-time disk copy. It rolls back bad updates or config mistakes in minutes. Most snapshots live in the same storage pool, so they alone are not disaster recovery.
Layered approach
- Snapshot: fast rollback, short retention
- Image / template: blueprint for new instances
- Offsite backup: separate location or object storage
Write down RPO and RTO
- RPO: how much data loss is acceptable?
- RTO: how fast must the service return?
- Test restore with a real file set
Versus VPS, cloud often automates snapshots more easily; VPS can still use agent-based backups. On KuzeyDC cloud servers, combine regular snapshots with periodic offsite copies. “Snapshots only” does not meet the 3-2-1 rule.
