The total amount of data is pretty irrelevant actually. It's more about how many passive copies you have, how large individual databases are, and where you have to store them.
I have a graduate school as a client that has about 2 TB of data, spread out over a dozen databases with two passive copies. I back up the passive copies to DAS and then compress them to NAS. I keep 30 days and then delete. It works well for them. I've got many other clients using DPM and various Symantec solutions. Regards, Michael B.

We are in the process of finalizing our Exchange 2010 deployment. We will be setting up Database Availability Groups for replication to two sites. The current 2007 deployment is over 4 terabytes in size and we anticipate that growing substantially since we are going from 2 gig quotas to 10 gig quotas right off the bat. We currently use Tivoli to backup information using lanfree backups and then those backups get written to tape. Backup times are going 8 to 10 hours at times for full backups. For 2010 we would like to go tapeless and just use replication, but we are getting pushback from upper management on this and the requirement to dump data to tape for offsite storage seems to be a pressing issue. My question is with 2010 what other backup solutions are available for the amount of data we are speaking about. If push comes to shove I would like to at least give upper management a few options so they get the warm/fuzzy and costs associated to the solutions. We would like to create a third site off campus and replicate data to the third site as well for DR purposes and possibly make that a lag copy. Management has the mindset that they would like data dumped to physical media that could then be sent to Iron Mountain which is where our mainframe tapes go for storage. If we lose both sites on campus...bring back the media....then rebuild. Sorry if this has been hashed through before.
