About NAS Backup
On ETH NAS (Network Attached Storage) daily backups are drawn.
Daily snapshots of files are taken on ETH NAS shares.
- Snapshots can be seen as a daily copy of files at a random time
- Snapshots are kept back for 6 days.
- Files from snapshots are directly recoverable by the end user.
Likewise to snapshots, daily backups are taken on ETH NAS share.
- Backups are kept for up to 90 days back
- Backups are drawn daily at a random time
- Files from backups are not directly recoverable by the end user.
For file recovery contact firstname.lastname@example.org and specify
- Exact path and name of the file or folder to be restored.
- Exact date and time of the version to restore.
- Exact date and time when the data has been lost/changed/corrupted.
File Recovery from NAS Snapshots or File Server
File explorer offers a GUI method to recover from snapshots:
- Browse to the folder of the missing file
- 2ndary click the folder, select “Properties…”
- Select the “Previous versions” tab
- Select “Open” on the appropriate snapshot and restore selectively what you need
Our system creates snapshots of your data on the Server or the NAS as the Following
- S4D-FS File-Server (Folder Redirection)
Every : 07:00 / 11:00 / 12:00 / 15:00 / 19:00 / 23:00
There will be stored up to 64 versions of all your data.
There are versions stored for up to 16 days back.
- once a day at : 13:00
There are versions stored for up to 6 days back.
Do only use “restore” if you’re sure it will not overwrite something newer or better…
Snapshots are available in hidden folders named “.snapshots”:
This basically works on any system, including Windows.
- Change to the share where the missing file/folder was
- Change into the snapshots folder: “cd .snapshots/\@GMT-YYYY.MM.DD-hh.mm.ss”
Browse through the files like normal and copy the wanted files back to NAS
There’s a list of folders containing daily snapshots from the past 6 days:
As above (UNIX). Typically the mounted NAS Shares can be found in “/Volumes”
Alternatively in Finder:
- “Menu”>”Go”>”Go to Folder…” (<shift><command><g>)
- Then enter the path, e.g. “/Volumes/example_share/.snapshots”)
Data which is no longer used on a regular basis should be moved to the LTS tape archive.
Data repository for departments: Saves compressed unstructured “Storage worthy” data. The optimal size for the data is between 10 and 200 GB.
