+<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.
