I have PBS running in a VM on PVE. Backup runs once a day during night. Normally there's not mucht to do as not much has changed and dedup does a good job. So PBS returns after 15 to 30 mins. Altough it does not consume much CPU and RAM during the rest of the day, I still wonder if it makes sense to suspend and stop it once the backup has completed and fire it up again short before the backup starts?

Someone doing this, any advice pro or con doing this?
 
I don't think it's worth the trouble but if you're worried about resource usage you could make it a CT.

The VM is consuming a bit more than 0.5% host CPU and and 2 GB RAM during idle. That's not much, but it sums up 24x7x365 and if i can stop wasting energy for nothing, i feel it's a kind of obligation we have on this planet.

I prefer to keep it in a VM for isolation reasons. That's why I was thinking about stopping or suspending it (might be the better choice).

What kind of trouble are you expecting with starting/stopping suspenging/resumgin the vm?
 
You need to put in time and effort to properly automate and time/coordinate this. You need to manually start it when you want to use it.
What if your automation tries to stop/suspend it during a restore? You need to figure out a lot of what ifs like that and that would give me trouble.
My PBS CT usually uses less than 500M by the way. It currently idles at 200M~.
