/projects
For backups of /projects, see the /backups directory on della9, stellar-intel, and tiger3. For instance, if your faculty sponsor is Alonzo Church or your NetID is aturing then:
$ ssh <YourNetID>@della.princeton.edu $ cd /backups/projects/ACHURCH $ cd /backups/tigress/a/aturing
You may be able to find previous snapshots in a hidden .snapshots directory, for example:
$ cd /backups/projects/ACHURCH $ ls -a .snapshots . .. SNAP-2025.01.27-19.18.40 SNAP-2025.02.03-19.18.40 SNAP-2025.02.11-14.01.13
Backups are made weekly.
/home
It may be possible to recover files that were removed from /home/YourNetID. This must be done by someone in Research Computing. Please send an email to [email protected] and be sure to include the cluster name (e.g., Della, Tiger) and the path to the files (e.g., /home/aturing/project1/data). Backups are made approximately nightly.
/scratch/gpfs, /scratch/network, /scratch and /tmp
Files on a /scratch or /tmp filesystem are not backed up.
