Vmlimitperhost
The vmlimitperhost option specifies the number of virtual machines (VMs) and virtual disks in a host that can be processed in parallel during an optimized backup operation.
An optimized backup operation is one in which parallel backup capability is enabled at the VM, virtual disk, or subdisk level.
The vmlimitperhost option works with the vmmaxparallel, vmmaxbackupsessions, and vmlimitperdatastore options to optimize backup operations and to help control the amount of resources that the backup can create on a host in the vSphere infrastructure. Adjust the values of these options to find the values that provide optimal performance for the backups that are in your environment.
