Well, this is still a problem. I don't use my desktop at home much - it dutifully goes to sleep after an hour of non-use. Thats fine.
But as others have stated, the scheduled 3am backup service job doesn't run (computer asleep) and only kicks off when I next power up the machine. This means there are 2 problems:
1) Nothing from my current days computer work will get backed up (as that the computer is asleep by 3am the next morning when its scheduled to run)
and
2) When I DO use the computer the next time, then backup is running and using the very limited upload bandwidth as well as disk/cpu activity, while I'm in need of the computer.

I've tried the approach found elsewhere on the internet to schedule a simple do-nothing task to wake up the computer - hoping that when that causes the machine to wake up the backup service will kick off - but so far unsuccessfully. Will have dig further into why that isn't succeeding.

Understand yours to be 'sleep' - I read in the Cloudberry Backup FAQ that the back will not run when the machine is asleep, as my home computer is want to be doing at 3am. So at present the only solution is to use the Windows 10 task scheduler to wake up the PC to 'do something' when the backup is due (and of course have the backup set to run as soon as the machine is awake).

It would be nice if Cloudberry Backup could wake up the machine at a set time (the way Windows Update seems to do) and run its backup at the scheduled time, so us users don't have to know/remember to keep two separate things in sync (the backup job schedule, and the windows task scheduler wake up command). Even better if one could have Cloudberry wake up the Win10 PC to do the backup and then put it back to sleep immediately following, though the normal sleep settings would eventually kick in and put the machine to sleep.
