That sounds fine to me. However, one recommendation I'd make is to use
maildir for the backup as well as the live mail instead of mbox. That
way you can easily delete mail from your backup over a certain age. Eg,
to delete everything over 30 days (untested):
find /var/spool/mail -type f -mtime +30 -exec /bin/rm -f {} \;
It would also be much more straight forward to retrieve mail from the
backup and then insert it back into a users current live mail...
