Backups, Restores, and Snapshots

For the past few years we have been outsourcing our backups to Brown University Center for Computation and Visualization (CCV). An incremental backup is done nightly (ummm, sometimes it takes more than one day to complete a backup, but most days it only takes one day so this is mostly accurate!).

The GPFS file systems, main and data, are backed up nightly and ten copies are saved (if you never change a file it will always be available, but if you change it every day for ten days your changes before those ten days will not be available). The nbu filesystem is not backed up at all.

Restores

To request a restore please send email to problem@cs.brown.edu. Restore requests are queued and attended to within three days (we try to have them done for you as soon as possible). If there is a problem finding what you have requested, you will get a message requesting more information. It will speed the process up if you are as accurate about the window of time the restore can be done from as possible.

Snapshots

The department file server has a feature known as snapshots which allows for online file recovery of recently (currently you can recover anything from the last three weeks) changed or deleted files. For details, see the Snapshots Page
