Is there a real error shown in the log file? If not, it could
just be a problem with the exit status of tar on the mac.
Perhaps it's a minor error (eg: can't read a file) that
causes an exit status that makes BackupPC think the backup
failed.
You could run this command manually (substituting the variables):
$sshPath -q -x -n -l root $host $tarPath -c -v -f - -C / >
/dev/null
and then print the exit status (echo $status in tcsh).

Craig,
Thanks a lot for your response. I've been otherwise occupied and
haven't had time to explore the above until recently.
I limited the backup to a very small set of files for testing and ran
the ssh'd tar command both manually per your suggestion and via
backuppc:
[backuppc]$ sudo -u backuppc /usr/bin/ssh -q -x -n -l root lucca
/usr/bin/xtar -c -v -f - -C / --exclude=.Trash --exclude=./Trash

So something is failing, but it doesn't appear to be tar. I can browse
the backup using the web interface and everything appears to be there
as the Xfer log indicates. Is there anything else that backuppc updates
upon a successful backup? A file with bad permissions perhaps? Any
other ideas?
Thanks!
Tony
