How about the following approach:
1. Full back up to DVD's once per 3-6 months. This will be for archival
purposes.
2. Between those DVD backups, back up to hard disks. From your data you
need to back up about 120GB per full backup (weekly backup).
In 6 months (26 weeks), total backup volume is 3120GB. Fits into 8
400GB hard disks (assuming that you do not need RAID for backup disks).
Does not seem to me to be that expensive.
3. I do not know how large are your daily incremental backups, but the
worst case is 6 days of 120GB each i.e. 720GB - two 400GB hard disks
(and in this case, I'd deploy RAIDs so you'll need more than two 400GB
hard disks).
