Which files are backed up, which aren't?

Please note: The FAQ pages at the HPCVL website are continuously being revised. Some pages might pertain to an older configuration of the system. Please let us know if you encounter problems or inaccuracies, and we will correct the entries.

By default, HPCVL maintains backups for the purpose of securing user data (disaster recovery) only, not for permanent storage or external use. This means that it is the responsibility of the individual user to remove data that are to be kept permanently from the cluster and store them on external media, such as disks, tapes, or DVD's.

User data that reside in the /home file system are backed up on a short cycle (in the order of days) to our L1400 tape library. This happens automatically as soon as a file appears on the files system. Whenever a file changes, the change will be committed to the backup as well.

Data that reside in /u1 are also backed up. The backup cycle is the same as for /home. No user data residing outside these directories are backed up. This holds specifically for /tmp and /scratch.
