Synology Hyper Backup Restore Missing Files: Diagnose the Offsite Restore Gap

You restored from your offsite Hyper Backup vault, the task finished without errors, but expected files are absent from the target folder. This is a common synology hyper backup restore missing files situation, and it usually comes down to how the restore job was configured rather than data loss. Work through these checks before assuming the backup is incomplete.

Confirm the restore version and scope

Open Hyper Backup, select the offsite vault, and click Restore. In the version list, note the timestamp of the version you restored. Then click the version’s details or browse view and compare the folder tree against what you expected. If the files are missing in the browse view too, the backup version itself does not contain them. If they appear in browse but not on the target, the restore scope was narrowed.

Check restore filters and folder selection

During restore, the wizard lets you tick specific folders and apply file filters. Re-run the restore and expand every folder node; a parent folder ticked without its children, or a filter excluding extensions, produces exactly this gap. Also confirm the target share has enough free space, since a full volume can silently skip remaining items.

Verification test

Restore a single known-missing file to a new test share using the same version. If it appears, your original target path or permissions caused the omission. If it does not, the version lacks the file and you should select an earlier version from the vault.

Rollback note

Before re-running a restore over existing data, rename the current target folder rather than overwriting it, so you can roll back if the new attempt changes more than expected.

If these checks do not explain the gap,

Ask for help with the version timestamp and folder tree.
