At 70% cheaper, the VXA is definitely the way to go, especially if most of
your backup data is being pulled across the network AND your backup data
will fit on one VXA tape (I hate swapping tapes). While backing up the local
machine to the VXA drive, Retrospect reported 4Mbps throughput at one point,
but the network backups are considerably slower (though still more than
twice as fast to the VXA than to a DDS-3). I think that the VXA has allowed
us to max out the network bandwidth, so we wouldn't see any real benefit
speed-wise by using a higher-dollar AIT.

We're actually using your second idea for our offsite backups. I set up an
old Motorola PPC clone with Mac OS 9, Rumpus, and a 50Gb LVD drive in
another facility...we do a local backup to the VXA, and an offsite backup to
an ftp storage set on the clone.

So, we never have to shuttle tapes back and forth for the offsite backup,
and a week's worth of local backups fits on one VXA tape. It all adds up to
a major decrease in the hassle factor of our backup strategy, and it didn't
cost much at all. That makes me happy, plus it impresses my boss. :)
