Exabyte just announced a significant price drop in their VXA prices
coinciding with the industry announcement that DDS-4 is the end of the line
for that technology.

For that much data the initial backup is going to span a stack of CDs ...
much better off with tape or possibly a storage set saved to an external
disk.  In fact using external firewire disks on the "backup server" as a
"removeable" medium works quite well.

Absolutely ... backup is pointless if you can't restore.

You really need to use a backup solution which will manage full and
incremental backups across multiple storage sets possibly spanning across
multiple pieces of media.

Further, given the price of the Qube3, the backup solution needs to be
priced right and targeted at the same client base that install a Qube3.  I'm
afraid that Arkeia, Legato, and Veritas simply don't meet these criteria.

Unfortunately due to NDA constraints I can't say more, but a Qube3 package
for the backup client I've been using on my Qube3s would be really cool.

Cheers,  Malcolm
