Also, be careful about VMs with several disks, since a single VM with let's say 5 disk is going to use 5 processing slots. You may want to place the jobs with those VMs to be started after others, but if for example a VM fails, is placed in the retry queue, so somehow your schedule is not going to be fully followed by Veeam. Unless you configure retries differently.
I'm in the phase of tuning our backup infrastructure after a couple of weeks using V7, right because of these kind of findings.
