Abstract: Hypervisor-independent reference copies of virtual machine payload data based on block-level pseudo-mount infrastructure and techniques are generated and stored in an illustrative data storage management system. An illustrative hypervisor-independent reference copy comprises one or more virtual-machine payload data files that originated from a first virtual machine. The hypervisor-independent virtual-machine-payload reference copy is governed by a distinct reference copy policy that controls retention, storage, tiering, scheduling, etc. for the reference copy, independently of how the illustrative system treats other virtual machine payload data files originating from the same virtual machine.
