Live mount of virtual machines in a public cloud computing environment
Live mounting a virtual machine (VM) causes the VM to run off a backup copy or snapshot previously taken of a “live” production VM. The live-mounted VM is generally intended for temporary use such as to validate the integrity and contents of the backup copy for disaster recovery validation, or to access some contents of the backup copy from the live-mounted VM without restoring all backed up files. These uses contemplate that changes occurring during live mount are not preserved after the live-mounted VM expires or is taken down. Thus, live mounting a VM is not a restore operation and usually does not involve access to every block of data in the backup copy. However, live mounting provides live VM service in the cloud sooner than waiting for all of the backup copy/snapshot to be restored. |
