I would rather have some NAS holding the backups across several sites
(hourly backups? rsynch?) then a huge pile of tapes that are odds-on to fail
regardless. The fact that terabyte storage solutions are now steaming in
well under £5k makes it possible to backup a few medium-sized departments
(providing they share a common baseline disk image) quite easily.

Nope. I've even seen SCSI in a room with broken aircon and ambient air temp
of 40C and not one of those drives broke. The problem with SCSI is that you
hand so much of a critical part of your system to a third-party controller.
Not very Von Neuman, but then I'm not a computer scientist. ;-)

We could start a new thread. ;-) What is tape if it's not a single point of
failure? If it bothers you, I'm not stopping you buying two of these and
putting in some synchro framework. In fact, it's quite likely what I'm going
to end up implementing in the next few months.
