+<note>As of mid 2011 we don't use Storix anymore.  The new HPC uses Amanda instead, as it is free, open-source software.</note>
 Tape backups are run manually __once per week__, __on Friday afternoon__.  We have four cassettes, each of which can hold seven tapes.  Our current tape backup needs are around ten tapes, so each pair has eleven tapes total just in case the size of the backups increases.  Each week we rotate the set of cassettes so that we always have a week of archived data.

 ===== Troubleshooting ======
+The following commands can be useful in determining problems with devices.
 ==== mtx ====
-Use the mtx command to help identify which hardware the OS detects.  For example, I have /dev/sg0, /dev/sg1, /dev/sg2, etc...:

+==== List SCSI devices ====
+'/dev/sg*' are apparently all SCSI devices (some of which are the disks attached to the OS), which can be quite confusing.  ''/proc/scsi/scsi'' will show you information about attached scsi devices:
