I appreciate the suggestions so far but I know how to measure usage

It sounds like you missed the point of Kevin's message (in the other
fork of this thread). The point wasn't to use `du`, it was that you can
run your stats against the backed-up files, not the source. Then you're
only running stats against the results of running the backup using the
filters, so you don't need to filter them again.
If that doesn't make sense or isn't possible (backups are on some remote
server), then just use your rsync command with '--list-only', and
post-process that list.
E.g., if your command is:
rsync -a --filter='dir-merge .rsync-filter' /source /dest
It becomes, with a post-processing command that just counts bytes from
files (not dirs/sockets/etc.): (all one command line -- munged for emailing)
rsync --list-only -a --filter='dir-merge .rsync-filter' /source /dest
| awk '/^-/ { total += $2 } END { print total }'
Post-processing is made simpler by the fact that rsync escapes "special"
characters already. (So, you don't have to worry about null bytes or
newlines or anything in the filenames.)
