I also opt in for missed backups.
We have our Endpoints connected to B&R. I tried using the trigger "When storage is connected". This doesn't help with B&R I believe, as our Windows 7 and 8 machines don't do them, not even when they boot up.
Only on my Windows 10 Notebook it seems to work, but has WLAN.
I then tried: daily schedule AND the trigger. but if the computer is off, no backup was done.
So either a missed backup feature, that doesn't only have a buffer of 15 minutes would be appreciated, or if Storage is connected it does it once a day, but B&R Repository is not like you plug any USB inside.
So kind of checking, is 1 day over, storage is there, then start backup.
We do have computers, that aren't used all the time, and used within different times between 8am to 2am, thus it's hard to schedule it.We can no only guess and hope, most of the times we hit the right time.
At Logoff I don't really like, as if you reboot, it might block that and takes time (not tested though).
Everything else works great, sure it would be nice if you could do settings through B&R instead of only direct at the computer of a set of computers.
