I've found that the version of rsync that Apple bundles is pretty squirrelly -- there are some posts in the archive about this. But generally speaking, there were some BackupPC-default rsync arguments that didn't play nicely with Apple's rsync.
I don't recall having issues with BPCv3, but with v4 --protect-args, --one-file-system, and --copy-links were problematic. Some of that are our client configurations, though.
