I'd try tar's d option. Presuming your host is named 'host', you're concerned
about the '/share' share, and it's mounted on your BackupPC server as
'/mnt/share', try something like

        % sudo -u backuppc /usr/share/backuppc/bin/BackupPC_tarCreate -h host 
-n -1 -s /share . | tar -C /mnt/share -df - .

You might need to use another method to become the backuppc user, your
BackupPC_tarCreate might be somewhere else (I think the default is
/usr/local/BackupPC/bin/BackupPC_tarCreate), and you might need root
permission for the tar to be able to read everything it is supposed to compare.
You might want to modify a file just to check that it is correctly reported.

Good luck, and please ask if you need more information.

Regards,
Holger
