Start with the NAS’s available recycle-bin, snapshot and backup copies. Which route works depends on the share, deletion method, system version and account authority. If none contains the required content, assess a supported storage-reading route without assuming that a network share exposes deleted data.
Identify the incident before changing storage
Record the NAS model, operating-system version, share, original path and deletion time. Note whether the deletion came from a client, File Station, an application or synchronization. Confirm that the folder was not moved and that your account still has access.
Preserve recovery copies and avoid unnecessary writes. Do not empty the Network Recycle Bin or delete snapshots while searching. Treat a failing storage pool as a separate condition; repeated restarts or rebuild attempts are not a deleted-file recovery procedure.
Inspect the available recovery areas
For a shared folder whose Recycle Bin was already enabled, open File Station and go to Recycle Bin. Select the required file and choose Recover, as described in the QTS 5.2 instructions. Inspect the destination first if a newer file may occupy the same path; verify the restored content afterward. QNAP’s deleted-file guidance explains the distinction between recycle-bin, snapshot and backup options. Use the instructions for the installed system.
If a suitable snapshot exists from before deletion, inspect the required path and extract the needed version where supported. Before restoring over current work or rolling back a larger scope, preserve any newer files that must survive. Also check an independent backup destination.
Enabling a feature or changing its retention settings after deletion cannot create a copy that was never captured.
Determine whether a storage scan is appropriate
Confirm that the relevant storage is readable and identify its actual file system and pool layout. Access to current shared files is not enough to establish underlying recovery access. Have the administrator assess whether the selected application’s remote or member-disk route matches this configuration.
XRecovery can connect to a readable NAS source over SSH with root access. Its Ext4 and Btrfs support covers remote scanning or quick scanning, with free preview for supported original files. Identify the file system actually used by your QNAP volume: support for these formats does not establish support for a different format, such as ZFS. Do not infer that a single removed drive can supply a multi-member volume.
If members are failing, a rebuild already failed or parameters are unknown, preserve the storage history for qualified assessment. Avoid creating a replacement pool or formatting members to make them readable in Windows.
Verify the specific result
Save recovered files to a separate destination. Open the needed content, check versions and examine dependencies for projects or databases. Keep outputs from different attempts apart so that a partial result does not overwrite a useful earlier copy.
Document what the recovery area or scan actually supplied and what remains missing. A visible directory tree is useful navigation evidence, but does not certify every file’s contents. Preserve validated output independently before returning the NAS to ordinary use.
