After files are deleted from a NAS, start with existing copies, not a Windows scan of the mapped drive letter. Check the relevant NAS recycle bin, snapshots and backups. If those cannot supply the file, determine whether an authorized, supported route can read the underlying storage while you save output elsewhere.

1. Record what happened
Record the NAS, share, path, deletion time and account that performed the action. Ask whether the file was deleted through File Station, a network client, an application or a synchronization task. The NAS’s recovery controls may not capture every deletion route identically.
Reduce avoidable writes to the affected volume. Do not empty recycle bins, delete snapshots or start storage-pool repair as part of searching for the missing file. If other people use the share, coordinate with its administrator so that the search does not silently overwrite current work.
2. Inspect the NAS’s available copies
Sign in with an account allowed to inspect the relevant recovery features. Look in the correct shared folder’s recycle area and examine any candidate’s path and content. An empty bin is not proof that no backup exists; it may not have captured that operation.
Inspect snapshots and backup versions from before the deletion. Prefer extracting a specific file or copying a candidate to a separate folder before considering a larger rollback. Verify that the copy contains the version and dependent files you need. Enabling a snapshot or backup feature now cannot create a past copy.
The exact controls differ by system. QNAP’s deletion guidance separates recycle-bin, snapshot and backup routes. Follow the instructions for your own system rather than assuming its labels match another brand.
3. Establish a supported scan route
If copies are unavailable, check whether the storage remains readable. Access to an SMB share normally exposes files the server currently offers; it does not by itself grant access to deleted blocks. Do not interpret a mapped Windows drive letter as proof that a local disk scanner can inspect the NAS’s underlying volume.
XRecovery’s documented remote NAS/Linux route requires SSH and root access. Have the authorized administrator establish the target and access method; do not assume that ordinary share credentials satisfy this requirement. Confirm the file system and storage configuration as well. If the NAS is unstable or its members are incomplete, obtain an appropriate assessment before further reads.
Example: a deleted project folder
Imagine a shared project was deleted yesterday. The administrator checks the share’s recycle bin and a snapshot from before deletion, but neither contains the needed version. The NAS remains readable and the administrator can provide SSH with root access. Record the project path and approximate modification date, select the matching NAS volume and use XRecovery’s supported scan route. Search the path and project name, then save the project and its linked assets to separate storage for validation. If the host cannot be accessed over SSH, resolve that connection first using the NAS connection help; a mapped share alone is a different access route.
4. Export and check the required files
Use this sequence for a readable source that matches XRecovery’s NAS support:
- Run XRecovery on a supported Windows computer. Have the NAS administrator confirm the target address and arrange SSH access with root privileges. A shared-folder password alone is insufficient.
- Connect to the authorized NAS source and identify the intended volume by its file system, size and expected contents. Ext4 and Btrfs support covers remote scanning or quick scanning.
- Scan the matching source. Use the available path, type, search and filter views to find candidates; supported original-file preview is free.
- Select a small set of required files and save them to separate storage. Open the exports in their usual applications before recovering the remaining files.
Ordinary scanning and supported original-file preview are free. Recovery and file repair share a cumulative 2 GB free allowance that does not reset. Test the files you need before deciding whether to purchase a license for a larger recovery.
For a folder, check its required contents and relationships rather than only the folder name. For a database or project, retain the unmodified export and validate a working copy with the relevant application. Record missing or incomplete dependencies.
If the scan finds nothing useful, retain the incident description, versions, source configuration and observed result. Use those details to determine whether the next step is correcting access, selecting a different source or obtaining specialist assessment. Resume normal storage use only after deciding how to preserve the remaining source and the validated copies.
