Working around a problem of a machine that crashes and
doesn't restart automatically seems like the inelegant part
to me. Is this something you can fix? If it isn't on a UPS,
even a small one might get it through short power glitches.
If you make your blackout interval cover the time when the
reboot is likely to happen, backuppc shouldn't start any
new runs until the blackout ends. That still won't quite
work since if you start at 5PM, 20 hours later will still
take half of the next workday. The other choice seems to
be making backuppc run scheduled incrementals only and
forcing the fulls manually or with a cron job.
