Reply to:   RE: using large hard disk as backup desitination

I'm really not sure why this was done. I'm assuming it was decided to wait until Apple 
lifted the 2GB limit before working around it in the software. Now that Apple has 
lifted the limit, that's our cue to change Retrospect's capabilities...

I'll be sure to flag this suggestion, though.
