When I use a amount of backup per vm on my backup storage I've got a message that maximum of backup is exist on storage I must remove a backup when I want do manual backup for my developers I think it's a little strange bechaviour
I think it's little useless I must create the same storage with some special option if I want do special backup.... but thanks for idea.
The second thing it's annoying for me It's a moment when one of node crash for example out of power and I must find which vm are off because I doesn't have name of vm only id (if I have more than 20 vm I'm sorry but I don't remember id's of vm)
