Retrospect - backup to disk?

Question

My disk space needing backup has grown to the point where it is no longer practical to backup to tape (5 GB per tape) or ZIP-style disks . So I figured I would tell Retrospect (v4) to backup to some spare fixed disk space I have.
That simple concept has turned out to be quite a BIG deal. I can't sem to get it to happen.
Have you a better plan for backing up 300 GB (give or take) on 3 separate computers? Or perhaps you've solved the "backup to disk" option. If so, please
tell me about it.
I like Retrospect (having v3, v4 and v5 available) but if you suggest a change to another piece of software, I'm open to the idea.

It's the Server version.
It definitely shouldn't have any file size limit, I definitely had 400GB+ single backup sets in Retrospect 5.
So again, which VERSION do you have ? open retrospect, apple menu, "About Retrospect...". Hoping that' it's mab missing an update that would resolve this.
I WAS working with v4.1i. But based on Hiroto's message I installed 5.0.201.
Can't find any options in Preferences or Script options that may limit the size.
It appears to be the older version I was using that limits the size.
OK, I had a look through the manual too. For AFP-mounted volumes, the maximum file size is 2GB before OSX 10.3. So either get a bigger internal disk or upgrade the OS. This restriction is also in Retrospect 6 so I suspet it's an AFP issue.
Ironically, after finding it in the manual, a google search for "retrospect 5 os9 2GB" finds it too.
Well Hiroto's message contained the clues I needed to get me going. The actual magic was to tell Retrospect to "Erase" the blank media (ie the FireWire disk). Then I was able to use the disk as the backup device sucessfully - after making sure the catalog file was somewhere other than the backup disk.
Thanks to you both.
