The CS department stores home directories and project directories on ZFS, a filesystem that includes native support for backup snapshots. We take snapshots every 24 hours at staggered intervals after 8pm (first /u, then /p, then /l), and store them for one month.

If you need a file restored from a backup snapshot, please send a helpdesk ticket to and include the full path name of the file (for example “/u/abc1de/public_html/myexcellentresearch”), and the date of the backup needed (ex. “from two days ago”).
