Absolutely.

My wife's machine has a Travan drive.  It cost about $200.  My
server has an HP DAT drive.  It cost about $400.  But her tapes cost
$70 for a box of three, and my tapes cost less than $4 each.  If you
keep a history rotation on your backups, it doesn't take very long
to come out even.

Plus, doing native backups on her machine take about 2 hours.  I can
use "smbtar" (a shell script wrapped around smbclient) to back up
her machine over our network in less than a half hour.

My vote?  Buy a serious tape drive (DAT, DLT) on a server, and back
up everything to it.
