talking with a client about various options for backup. They are an
advertising agency so most of the space is used by various binary files

We have been using LTO-2 but if we jump up their storage to say 2Tb,
that's going to be $5000 for LTO-3 with magazines. This affords us 3
week rotations rather simply.

If we add hard drive storage for backups instead of buying LTO-3 tape
drive, how much storage would we want for backing up 2Tb of binary
data...surely not 6 Terrabytes?
