I'm with you on the power thing, but that NetServer looks like it probably
sucks a ton of power when idle (lots of fans, over-speced power supplies).
If you've seen those $30 "Kill-A-Watt" things, they are an eye opener if
you go and measure all your boxes. My G5 sucks 247W under a nominal load.

Personally I've hated DDS tapes since I tried to pull a backup off a two
year old tape. Nothing of use was left, it doesn't seem to be a very
long-lasting medium. Once I free up some more space and shuffle the home
boxes around, I'm going to a disk-based backup like I do at work. No
tapes to change, and if you go across two disks or use RAID, it's not
putting all your eggs in one basket.
To manage this at one client I'm using Flexbackup. Very nice and simple
if you have from 2 to 2 dozen machines. I run a two week cycle and each
cycle goes to a separate drive. So if a drive on the backup server dies,
I lose at most two weeks. You can shuffle this around in any way you
As far as the archiving methods, you can use dump, pax, afio, rsync, tar;
just about anything you want.
