Restoring Deleted Files

Nightly snaphots of the file system are available for the last 30 days.

CCV does not guarantee that each of the last 30 days will be available in snapshots because occasionally the snapshot process does not complete within 24 hours.

Restore a file from a snapshot in the last 7 days

Nightly snapshots of the file system are available for the last 5-7 days can be found in the following directories.

Home directory snapshot

/gpfs/.snapshots/<yyyy-mm-dd>/<home>/<username>/<path_to_file>

Data directory snapshot

/gpfs/.snapshots/yyyy-mm-dd>/data/<groupname>/<username>/path_to_file>

Scratch directory snapshot

/gpfs/.snapshots/<yyyy-mm-dd>/scratch/<username>/<path_to_file>

To restore a file, copy the file from the snapshot to your directory.

Do not use the links in your home directory snapshot to try and retrieve snapshots of data and scratch. The links will always point to the current versions of these files. An easy way to check what a link is pointing to is to use ls -l

e.g.:

ls -l /gpfs/.snapshots/2020-07-15/home/ghopper/data
lrwxrwxrwx 1 ghopper navy 22 Mar  1  2016 /gpfs/.snapshots/2020-07-15/ghopper/scratch -> /gpfs/data/navy
