Data protection

Use snapshots and replication for different jobs

Use snapshots for short-term rollback and replication for an additional copy, then verify retention, credentials, and restore steps.

Snapshots stay close to the source

Snapshots can help recover earlier versions, but their failure boundary may overlap with the primary storage system.

Replication adds a destination decision

A replicated copy needs its own capacity, retention, connectivity, and recovery access plan.

Restore remains the proof

A protection feature only adds value when you can retrieve the needed files or service data within the required time.

Continue planning

Turn this storage question into a capacity baseline.

Use the planner to make growth, bays, redundancy, and recovery capacity visible together.

Compare protection layers

Recovery

Use RAID for availability, not as the only backup

Recovery proof

Test a NAS restore before an incident

Editorial record

Maintained by Make Your Own Tools to turn “Store data safely” into a defined capacity, bays, redundancy, and recovery baseline. The references below provide the technical context for this planning path. Its calculation rules and planning assumptions are documented in the methodology, and affected calculations pass regression checks before the review date advances.
