1. In a plurality of networked computer servers having first and second servers, wherein the first server has executing therein a first virtual machine with a plurality of virtual disks, a method of replicating the first virtual machine to a second virtual machine executing on the second server, the method comprising:

  • transmitting the virtual disks of the first virtual machine to the second server, wherein each transmitted virtual disk corresponds to one of a plurality of virtual disks of the second virtual machine, and wherein the virtual disks of the first virtual machine have a first format and the virtual disks of the second virtual machine have a second format;

    capturing a plurality of updates to virtual disks of the first virtual machine;

    identifying contiguous data blocks in the virtual disks of the first virtual machine that are subject to the captured updates; and

    transmitting the identified contiguous data blocks to the second server for storage in the virtual disks of the second virtual machine.
