Kenneth, within a job, VMs are processed sequentially. If you want the VMs to be processed concurrently, put them in separate jobs and schedule the jobs accordingly. (I'm assuming here you have local storage on both hosts, do you?)

Consider using the offhost backup mode to take data processing off the Hyper-V host. Please review the product user guide for details.
