The first mistake is in using rsync on mail folders - they are far too
dynamic.
Possibly faster suggestion:
1) use tar to transfer the folder contents to a NEW folder on the
backup system.
2) replace the OLD folder with the NEW folder on the backup system.
(something like this)
# cd /tmp
# ssh tar clf - /var/spool/postfix | tar xvf -
# mv var/spool/postfix /backup/path
