Recovery

Use RAID for availability, not as the only backup

Plan the primary NAS and recovery copies as different jobs. The backup has to be reachable when the primary array is not.

Name the failure boundary

Drive failure, accidental deletion, malware, hardware failure, and site loss are different events. A storage plan is complete only when each important data set has a recovery path.

Keep copies independent

An external drive, second NAS, or remote destination can be independent. The exact choice depends on data size, restore time, and location risk.

Test a representative restore

Choose a file set, document the steps, perform the restore, and record the result. A green backup job is not the same as a usable recovery.

Continue planning

Turn this storage question into a capacity baseline.

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