Retrieving deleted files from snapshots

You can retrieve old versions of or deleted files from snapshots. This works for files in the /t3home and /work areas, but each area has a different way to access the snapshots.

Accessing /t3home snapshots

Access the special ~/.snapshot directory to list the available snapshots

$ cd /t3home/$USER/.snapshot
$ ls 
daily.2019-02-26_0010  daily.2019-02-27_0010  monthly.2019-02-01_0010  weekly.2019-02-24_001

Accessing /work snapshots

The snapshots are available through a separate mount on the UI nodes:

ls /work_snapshots
base-copy              snap-daily-20260403-063001  snap-daily-20260407-063001
snap-2021-01-26T18:59  snap-daily-20260404-063001  snap-daily-20260408-063001
snap-2021-01-29T23:41  snap-daily-20260405-063001  snap-daily-20260409-063001
snap-20210201-215535   snap-daily-20260406-063001

The earlier access through the special ZFS mediated mount under /work/.zfs/snapshot was not stable, so please use the method documented above.
