For a solid back up I am looking at tape, well the iomega rev tape system with the highest compression for a SATA connection that I have found so far. It is 70/140 native and 240 compressed.

You could also use a hot swappable SATA SAS array

If 240GB if enough for your dailies, then thats probably your best bet. I would recommend investigating other options besides Retrospect though.

I wouldn't know of any other back up medium to use other than external hard drives, or off site data centers. Right now I have roughly 70-80GB that is backed up daily on my secondary workstation that has 2 TB of space right now, but that only holds so much before I need to either determine it is safe to delete some of the older backups.

I am anticipating within the next year for the backup to jump from 70-80 to about 140-150 a day. I am going to have to sit down and really plan out my data solution for the next few years so I am not forced to get more hardware or upgrade again in a few years.

Planning is always important, it will save you money in the long run. You could even use LTO tapes if you ever need more space, the newest being LTO3 with storage of 400/800.
