After creating a backup job using the Agent for VMWare and adding two duplicate job stages to run at the same time, both jobs will run, but only one of the duplicate jobs will complete successfully. The other duplicate job will fail.
Unable to open a disk of the virtual machine.
Due to a VMware limitation, multiple duplicate jobs from the same source cannot run at the same time. When a disk is opened, VMware locks the disk. Subsequent attempts to open the disk will fail until the lock is removed. The lock is removed when the disk is closed.
Use the "According to schedule" option to stagger the jobs to run at different times.
