For simplicity, you could try the Sonicwall CDP series of backup appliances.
You have one local device which does the backups and most restores (Including
versioning), and then a remote device elsewhere (you can pay for Sonicwall to
do it but megabucks, or host it elsewhere). They are SQL and Exchange
compliant, and the larger units are in RAID 5 array.
Alternately (Which is what we do for our single Terabyte data), backup to local
drives and remote NAS or similar. TBH, I'd disagree with Jim that hard drives
are as fallible as tape - we've never yet failed to restore from disk after
using them as our primary backup mechanism in a lot of environments over 5
years. *Waaaaaaayyyyy* less trouble than tape. I'd agree with Jim that a
*single* USB drive as *unique* backup is asking for trouble. But multiple
network ones cover the hardware failure and geographic failure.
On a bigger scale, get a couple of Netapp boxes with their dedupe software on
and let them do it. But first find your budget because that is not cheap :).
Of course, the remote backup assumes you have the bandwidth to do your
incrementals overnight/live - if you are in the middle of nowhere with low
budget then you will need portable cartridges of one sort. If it's a small
amount of data, REV drives might do the job - faster than tape (At similar
price points), and IME more reliable as well - but only go up to 120GB. They
also don't require regular replacement.

Jim,
I can see your points, but one thing is, we do not remove our USB drives, we
have multiple sets in multiple buildings and they do not move.
My biggest hurdle with tapes is sixty bucks a pop minimum and the boss says "no
way". Now if someone had a written reason that made clear sense in upper
managerial terms why tapes make good business sense, that I could drop on his
desk...
Thank You

Jak: as someone who has been backing up systems going on 30 years now I can
only say that for the foreseeable tapes will remain the gold standard. A
dedupe system for interim backup to disk makes sense for short term restore,
from the dedupe you can backup from it at any time reserving your servers
resources. Tapes are more portable and allow flexibility to have more
increments available. Just how many hard disks are you going to carry around?
We back up several terabyte of data per month.
In disaster recovery the chance you will be able to get the same model
servers/controllers is usually pretty slim. You will be left with a huge mess.
I wouldn't trust my job and my companies reputation/well being against USB
