Manufacturer documentation example of File Station restoring an item from #recycle. This separate DSM fallback needs an existing retained item; it is not Drive Version Explorer or evidence that Drive versions exist.
Manufacturer interface example: File Station shared-folder recycle-bin recovery.[4]
For an unwanted edit, inspect the file’s available Drive versions and retrieve a separate copy for the owner to verify. For a deletion, identify whether the item is recoverable in Drive or the DSM shared-folder recycle bin. If the NAS, Drive data or retained history is unavailable, the recovery requirement moves to a separately protected copy.
This guide covers ordinary files on a DSM 7 Synology NAS. Synology Office documents have a separate history and database path. Record the actual DSM and Drive builds, the original path and the last known good content before choosing a recovery action.
Choose the path from the failure, not the application name
Ask what changed and when, which account owned the file, and whether other devices are still editing it. Preserve any current copy that may contain useful work. If many files are unexpectedly changing, treat the cause as an incident before returning restored files to active synchronization.
| Observed failure | First route to inspect | Limit to establish |
|---|---|---|
| A current file has an unwanted edit | Available Drive version history | The needed version was retained before the error. |
| A file was deleted from a Team Folder | Drive Recycle Bin or administrator Version Explorer | Versioning was enabled; the item was not permanently purged. |
| The Drive item was permanently removed | The independently enabled DSM shared-folder recycle bin, then protected copies | A separate retained copy must actually exist. |
| The NAS or its Drive data is unavailable | A separately available snapshot copy or independent backup | History stored with the failed system cannot establish independent recoverability. |
| The file came from a client Backup Task | That task’s restore workflow | Confirm the backup source and destination; do not assume it is a sync task. |
Use the Drive missing-file diagnostic first when the file is still present on the server but absent only on one client. Downloading an old version will not correct an excluded task folder.
Retrieve an earlier version before overwriting the live file
In the Drive web portal, locate the file and open Version history. Select the candidate version and use an available download or copy action to inspect it separately. Choose Restore only after confirming that replacing the working content is the intended action. The official recovery procedure also documents previous-version access through Drive Client and administrator Version Explorer.[1]
Ask the owner to verify something meaningful: a corrected paragraph, worksheet value, drawing revision or another expected change. A matching filename and a successful download do not establish that the content is the wanted version. Keep the accepted version and the overwritten/current copy distinguishable until the decision is complete.
Illustrative recovery case: a project specification contains yesterday’s approved wording and a later incorrect edit. Retrieve a candidate historical copy into a review location, have the owner compare the relevant section, and agree which active file should be replaced. This is a worked method, not a claim about a completed client recovery.
Handle deleted files with the correct recycle bin and identity
The Drive web portal places deleted items in its recycle bin only when the parent folder has versioning enabled. Deleted Team Folder items are in that Team Folder’s recycle bin, which the current help limits to administrators. An employee’s empty personal recycle-bin view does not prove the team’s file is gone.[2]
An administrator can inspect Drive Admin Console > Team Folder > Version Explorer, choose the relevant view and date, and show deleted files. Avoid permanent-delete actions while investigating. Once a file is purged through Drive’s recycle bin or Admin Console, the official recovery article says Version Explorer cannot bring it back.[1][3]
The DSM shared-folder recycle bin is a separate possible fallback if it was enabled beforehand and still retains the item. In File Station, inspect the share’s #recycle folder. For DSM 7.1 and later, Synology documents a Restore action to return the deleted item to its original location; the documented DSM 7.0 path uses Move to. Confirm the destination and the active-folder consequences before using either.[4]
Know which recovery promises the settings can support
Versioning is a retention policy, not an unlimited archive. Record its actual version count, rotation policy and any scheduled age-based removal. Reducing the maximum count removes excess versions after the setting is applied. Do not lower history limits or empty bins as a space-cleanup shortcut while someone is trying to recover data.[3]
Package backup has its own boundary. Synology’s DSM 7 Drive backup documentation says Hyper Backup can protect package data and settings, recommends including Synology Office when its documents are required, and explicitly excludes historical versions of ordinary non-Synology Office files from that backup. Do not promise that restoring a Drive Server package will reconstruct every old version visible before the failure. A package restore also overwrites current package data and settings; plan it separately from retrieving one file.[5]
For a backup-based file retrieval, choose a safe destination and retest access. The Hyper Backup restore help states that Copy to and Download do not retain original privilege settings. The recovery record must therefore distinguish recovered file content from restored permissions.[6]
Accept the recovered business file and its access separately
Use a small drill before an emergency: create an agreed test file, make a recognizable edit, and delete a disposable copy in the intended scope. Confirm which identity can retrieve each item, where it lands and how the owner knows it is correct. Do not permanently purge production files merely to demonstrate the boundary.
| Record item | Evidence to keep | Acceptance question |
|---|---|---|
| Original identity | Folder, filename, owner and incident time | Did we investigate the correct file and role? |
| Recovery reference | Source version, date, task or recycle-bin location | Does this retained state predate the unwanted change? |
| Separate verification copy | Retrieval path and owner’s content check | Does the recovered document contain the required work? |
| Working destination and access | Replacement decision and ordinary-user permission tests | Can the right people use it without exposing it to others? |
| Final synchronization result | Observed receiving-device content after the approved change | Did the accepted file reach the intended clients? |
Record anything that could not be recovered. A useful drill can reveal a missing retention policy or backup exclusion before a critical file depends on it. Use the Synology snapshot and Hyper Backup recovery tests to evaluate the separate NAS-level protection, and the Drive deployment checklist to make versioning and ownership part of acceptance.
Make the recovery requirement part of support
ALLMSP Synology Drive support can help identify the actual recovery source, test a small restore, validate ordinary-user access and document the limits. For a broader recovery plan, bring the required point in time, the unavailable system or data, the existing backup task and any encryption or account dependencies.
The useful outcome is a verified file and an understood recovery boundary. Neither a history icon nor a completed backup job, by itself, proves that a particular business file can be recovered when needed.
Frequently asked questions
What should I try first after an unwanted edit in Synology Drive?
Inspect the available version history and retrieve a separate candidate copy for the owner to verify before replacing the working file.
[1]Can Drive recover versions that were never retained?
No. Recovery depends on an available retained state. Confirm that versioning was enabled and that the required version survived the configured rotation policy.
[3]Why can an employee not see a deleted Team Folder file?
The current Drive help makes a Team Folder’s recycle bin accessible only to administrators. Have the authorized administrator inspect the correct Team Folder and recovery scope.
[2]How can an administrator inspect deleted Drive files?
Can Version Explorer recover an item permanently removed from Drive?
The official procedure says items purged through Drive’s recycle bin or Admin Console cannot be recovered through Version Explorer. Check a separately retained recovery source.
[1]Is the DSM shared-folder recycle bin the same as Drive’s recycle bin?
No. It is a separate possible recovery route that must have been enabled and must still contain the item. Inspect the share’s #recycle folder in File Station.
[4]What happens if the Drive maximum-version count is reduced?
Excess versions are deleted after the changed setting is applied. Preserve the recovery requirement before reducing history or clearing bins.
[3]Does Hyper Backup preserve every historical Drive version?
No. Synology’s Drive package-backup documentation excludes historical versions of non-Synology Office files. Verify the actual task scope instead of promising a complete history rebuild.
[5]Will downloading a Hyper Backup file retain its original permissions?
No. Hyper Backup’s Copy to and Download retrieval methods do not preserve original privilege settings. Verify the recovered content and destination permissions separately.
[6]What proves a file recovery was successful?
The owner verifies the required content, the approved destination is correct, ordinary-user access is appropriate, and the accepted file reaches the intended clients. Record the source version and observed results.
