Thanks very much Ryan.

The one important take-away point that differs from the previously
explained backup plan is that backups are put into the backup system
only every other day.  We do keep the prior days backup, for 1 day
only, on disk on papio until it's overwritten by the next days backup.
So, in case of disaster we could lose 2 days of work.

Ryan, the only thing I can think of that might go wrong is if
the database backup is being written at the same time that
the backup is done to tape.  This would leave us with an
incomplete backup on every tape.  (It would also be good if
the database backup to /disk completed before, rather than after,
the backup to tape so there's not another day of lag introduced.)

Just thought it's worth mentioning the above just in case.
