-====== Tape backup ======
+====== Storix ======
+<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.

 ====== Storix Backup Administrator ======
 We are using an Exabyte Tape library for backups and the commercial Storix Backup Administrator software [[http://www.storix.com/]].

 To make more than one backup to same tape:
 Use ''/dev/nst0'' instead of ''/dev/st0''. This does not rewind the tape after the first backup finished.

+==== 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:
+<code>cat /proc/scsi/scsi

+Try to reset the library and drives from the front panel.
