Re: Nightly routine running at the same time as backups

Hi,

as you worded: it is not critical. Obviously, it might affect 
performance. No curruption in case they run in parallel.

You should schedule it to a time when backups only run rarely. Possibly 
not at the same time when most backups start. So for your case with the 
blackout period from 6-23 I would prefer to have the BackupPC_nightly 
run at 5 (when most backups are done through the night). So your first 
entry there should be "5".

I am unsure how the WackeupSchedule and the blackout periods work 
together. From my point your current settings do not match each other... 
I guess the blackout period overwrites the wakeups...

However, set it to 5 and in most cases there should be no backup in 
parallel (as long as your backup windows has enough slots to backup all 
scheduled hosts).
