Snapshots & Replication
Point in time copies and continuous copies of data, powerful recovery tools that are not substitutes for backup.
IntermediateUpdated 2026-09-01
Overview
Snapshots record state at an instant and allow rapid rollback, typically stored on the same system as the source. Replication continuously copies data to another system, synchronously for zero data loss or asynchronously across distance.
Neither protects against logical corruption or malicious deletion that is replicated onward. Both belong in a design alongside independent, immutable backups.
