David,

thanks for the insight,

My first thought was to use a hard drive for backup, but I see the 'big' 
boys all using tape

so I figured there must be a downside to using a hard drive vs tape.

Good ones are expensive. I've never been disappointed with
Seagate/Conner/Archive SCSI DDS (4mm) drives.

DDS-4, AIT, and DLT are candidates.

You might consider purchase of cheap 30 or 40G ATA drives and mount in
quickie removable plastic trays which seem to be under $20 each. Not
terribly impractical when a 35G DLT tape's price is compared. Dell
Optiplex PII-300's are coming off 3 year leases in droves at the moment.
Not hard to find a clean one for $120. Put FreeBSD on it. Mount one of
those removable ATA trays. Connect to the same network as your server.
Backup to the removable HD.

When 5400 RPM 40G HD's hit $115 I bought one for work and installed it
in my PowerMac G4-400. Retrospect runs every night backing up my Mac's
other HD's and (4) Windows NT systems. One nice thing about the HD is
that there is much less wear and tear than with tape drives. Never have
to clean the HD's heads.
