Synology Offsite Backup: Restore a Sample and Verify It
Category: Backup & Restore
A Synology backup task can complete while the restore path is broken or the scope is wrong. Restore a small sample to a separate folder and inspect it.
Before you start
- Synology source and offsite destination
- Access to Hyper Backup or the configured backup tool
- One sample folder with known files
- Free space for a separate restore
Step-by-step checks
Step 1: Write the protected scope
List the shared folders and applications in the task. Confirm the sample you will restore is inside that scope and has a known file count.
Check: The sample path is explicitly covered by the backup task.
Step 2: Verify the destination
Open the remote destination and confirm the latest version exists. Check free space and that the remote device is not the same failing volume.
Check: The destination is reachable and has a recent version.
Step 3: Restore to a new folder
Use the restore wizard to restore the sample to a new location. Do not restore over the live share or select the whole volume for the first test.
Check: The restore completes without overwriting live data.
Step 4: Compare contents and metadata
Count files, open several types, and compare modification dates and permissions with the source. Note missing or changed items.
Check: Every sample file is present and readable.
Step 5: Record the recovery point
Write down the version timestamp, restore path, and result. Repeat the restore after a new backup only if the first test exposes a gap.
Check: The handover note identifies a known-good recovery point.
Verify the result
The sample restores to a separate folder, opens correctly, and matches the source count and key metadata. The tested version timestamp is recorded.
Rollback
Remove only the separate restore folder after verification. Keep the backup versions and the live share untouched.
