Calendar Schedule issue

I have noticed that you weekly runs (and the Monthly one) have the following windows:

Calendar sched: Enabled
Sunday, Week 1
Monday, Week 1
Sunday 18:00:00 --> Monday 08:00:00

As these are calendar schedules each day is a new day. This means that you are asking the backup to run at 1800 on Sunday and again at midnight on Monday

You may get away with it if it is a large system and takes a while to back up but if not it will try and run twice.

Your window should be Monday, Week1 Monday 00:05:00 --> 08:00:00

Best not to cross midnight with calendar schedules

Likewise you Daily also crosses midnight so can run at 21:00 on Monday and could then run again just after midnight Tuesday. This would make the next run not actually happen until just after midnight on Wednesday

This would have an effect on any exlcude dates also.

Best tidy all of these up if possible as it could be contributing to your issues and running at unexpected times (I wouldnt expect any to start until midnight during the week apart from on Monday)

Hope this all makes sense and helps
