Last night the server backup hasn't started because the server was actually sleeping during the configured start time. That made me wonder if the option "Always on during configured backup time" actually contains the server backup schedule as implied on the help page.
My client backups are scheduled to be done between 22:00 and 23:00. The server backup is scheduled to be started at 01:00 every day.
The "Monitoring" page in the Lights-Out settings looks like this:
This is the first time that the backup was missed because the server was sleeping during the scheduled time. I was in the impression, that Windows SE wakes up itself automatically at the scheduled backup time, isn't it? Maybe this just failed to happen for whatever reason this morning?
BTW, I just added a review to MS Pinpoint for Lights-Out. It's well earned!
