Not enough room to transfer

[SReubart]

For some time I have been trying to copy one of my backup sets (from several weeks ago) to another set, so that the destination set will be small enough to fit onto my 20GB offsite drive. I usually do this by using the Tools > Copy > Transfer command to copy between sets, and tell it to not to copy snapshots and to select only the most recent version of each file. This reduces the size of the resulting set enough to fit.

 

 

 

With the set I'm trying to copy now, it scans through all of the files in the source set, then says that the files are occupying 580.0 GB! This is clearly impossible, as the source set is on a drive that has a total capacity of only 22 GB. So of course when I try to do the transfer, it says that there is not enough space on the destination to complete the copy. (The destination drive has about 24GB open.)

 

 

 

I have rebuilt the source set's catalog a number of times, thinking that perhaps something was messed up there. But it doesn't make any difference.

 

 

 

Does anyone have any ideas? My entire offsite backup strategy depends on being able to do these transfers, and if they don't work I'm screwed.

Under Configure>Backup Sets for this set, what is listed on the Summary tab next to "Used"? Also, how is the destination drive formatted? HFS or HFS+? I wouldn't imagine that filesystem issue to balloon the filesize, since this is a transfer between sets, but it might give us a clue.
