rdiff-backup and computer suspend

[Eric Beversluis]

When I get up in the morning my rdiff-backup process hasn't finished. I 
can't figure out if it's taking all night (it's a pretty big backup, 
since it includes the Windows VM) or if, for some reason, it's hanging 
up during the night.

So my question concerns how suspend work on Ubuntu. I assume that the 
computer doesn't suspend if a process like rdiff-backup is running. 
Maybe that's wrong. But I've always thought the computer wouldn't 
suspend as long as there was activity. And if the computer does suspend, 
does that mean that the rdiff-backup process also suspends?

Is there a way to have the computer only suspend once the backup process 
completes?

I'm running Ubuntu 20.04.6 LTS 64-bit on Dell XPS (Dell Ubuntu image)

Thanks.
