If the backup takes 20 minutes, and starts at 10, when it gets to the
next wakeup, 11, the backup will only be 40 minutes old, or 0.028 days
old. As 0.028 is less than 0.1, it won't start a new one. In fact, 0.1
days is 2.4 hours, so if your backup takes less than 20 minutes, it will
back up every 3 hours, or every 4 hours otherwise!
It isn't anything I have ever tried, but my first attempt would be to
remove the blackout periods, then reduce the $Conf{IncrPeriod} to 0.01,
and hope that the backups take less than 45 minutes, else this number
will need to be even smaller! I don't know if there are any limits on
this.
As Louis said, some idea of what isn't working would help!
