I tried "When my computer starts" , but MR doesn't do anything. When choosing "At logon" it works. Any idea what's causing this?
I can't say I have really, but the first thing I'd suspect would be fast-startup interfering & would try with it disabled, just to see what happened.
As to your second question, I'd imagine they'd get logged as failed jobs, it's easy to go check the logs on your machine though & then you'd have a definitive answer.
You might try hibernating the machine if you know a backup started, that ought to cause it to simply resume the next time you woke it.
