1. A method comprising:

  • backing up a first virtual machine into a first backup copy of the virtual machine stored to a first secondary storage device,wherein the first virtual machine executes over a first hypervisor operating on a first virtual machine server,wherein the first virtual machine accesses data that is stored in a primary storage device that is communicatively coupled with the first virtual machine server, andwherein the first backup copy comprises, in a hypervisor-independent format, one or more configuration parameters of the first virtual machine;

    configuring a second virtual machine, based on the one or more configuration parameters obtained from the first backup copy,wherein the second virtual machine is configured over a second hypervisor operating on a second virtual machine server which is distinct from the first virtual machine server;

    restoring the first backup copy to the second virtual machine, which is in communication with a primary storage device storing restored data in native format accessible to the second virtual machine; and

    synchronizing the second virtual machine to the first virtual machine, comprising;

    periodically backing up the first virtual machine to successive incremental backup copies comprising changes relative to a respective preceding backup copy of the first virtual machine, andrestoring each successive incremental backup copy to the second virtual machine, thereby making the second virtual machine ready to operate instead of the first virtual machine, based on the most recent incremental backup copy of the first virtual machine restored to the second virtual machine.
