Jeff,
We've discussed at least one issue off-list - making sure you consider
inodes too.
It looks like BackupPC_fsck -f only rebuilds the last two backup refcounts
for each host. It should use the -F option instead of -f when it calls
BackupPC_refcountUpdate (see line 630). So you should try changing that
and re-running.
