====== Backup and recovery ======
A backup is a separate copy that can be restored after deletion, disk failure or a bad change. Synchronization keeps working copies aligned; it is not a replacement for a backup.

===== Plan =====
Choose important folders, a second NAS or supported target, a schedule and a retention policy. Confirm available capacity and permissions before the first run. Keep at least one copy independent from the source device.

===== Verify =====
Run a small backup, inspect the result and perform a test restore to a separate directory. Check file counts, sizes and hashes. A job that reports “uploaded” is not proof that a restore has been tested.

The current service does not send NAS data through the application catalog server. The selected target receives the backup according to the configured transport.
