Abstract: The disclosed “Live Mount In Cloud” solution enables, within a cloud computing environment that houses a desired backup copy made from a source virtual machine, immediate access to backed up data on demand without restoring the backup copy in its entirety. Live Mount In Cloud also enables the live-mounted VM to write new data, not just to read from the backup copy. Live Mount In Cloud creates multiply nested VMs within the cloud computing environment. Accordingly, the live-mounted VM runs in (is hosted by) a hypervisor nested within a cloud-native VM. Live Mount In Cloud handles any differences between formatting and configuration settings of the hypervisor hosting the live-mounted VM and the way in which the backup copy is formatted. A backup proxy VM intercepts reads and writes issued by the live-mounted VM and facilitates access to the backup copy.
