Restoring Deleted Files

Nightly snapshots of the file system are available for the last 5-7 days.

CCV does not guarantee that each of the last 7 days will be available in snapshots because occasionally the snapshot process does not complete within 24 hours.

Snapshots 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.

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

If files to be restored were modified/deleted more than 7 days (and less than 30 days) ago and were in the HOME or DATA directory, you may contact us to retrieve them from nightly backups by providing the full path. Note that home and data directory backups are saved for the last 30 days only.
