You just need a PetaSite library.

And I think the SAIT-3 drives are supposed to be out soon (5TB / media
compressed).  You'll only need 3 or 4 tapes for a full backup.

120MB/sec compressed data is the goal I think, so about 250MB/sec
uncompressed.  Or 900GB/hr.  So your backup wont even take all day.

FYI: I have no idea what transport they may be using for 900GB/hr, but
I think I did the math right.
