[rdiff-backup-users] Result too large [Errno 34] on OS X

[junk]

I've been trying to get some backups running on my OS X (10.4) system and
am running into the error below after a few gigs are backed up.  After
receiving this error my backup directory is not recognized I've attempted
disabling compression as well as reading the man page and all of the
documentation and posts that google would return.  Has anyone seen this
error, and if so could you point me in the right direction.

Command:
nice rdiff-backup --no-compression --exclude ~/workspace --exclude ~/Music
--exclude ~/downloads --exclude ~/Documents/Virtual\ Machines --exclude
~/.m2/repository ~ /Volumes/Backups/backups

Exception:

Exception '[Errno 34] Result too large' raised of class 'exceptions.IOError':
