Backups are worthless if you can't restore them. Test your restore process before you need it.
Restore scenarios:
Device replacement: New hardware, same config. Copy backup to new device, verify, and swap.
Accidental misconfiguration: Roll back to last known good config.
Factory reset: Device lost its config. Restore after re-establishing management access.
Restore checklist: Verify firmware version matches, check interface naming differences, test management connectivity first, and keep a rollback plan ready.
Document your restore procedure for each device type.
