Starting with the real time clock, then shutting down afterwards, is
an excellent idea for extra security for backups.   This lowers the
vulnerability of the backup server to external attack.  It might be
even better if you can move the starting time randomly, so that the
time the backup server is exposed changes.  You should design your
backup script so that if dirvish-runall does not complete, it still
schedules another backup the next day.

As Dave Howorth suggested, you can run a "wrapper" script from
cron.daily;  a simple one is here:

Note that I mount and unmount the backup drive, and I create a
one-line log entry.  I actually use a more elaborate script, with
more security features, but you can start from the simple one.
