Abstract
Methods and systems for utilizing local storage of host computers to emulate a centralized storage system comprise receiving a write operation from a virtual machine running on a first host computer, wherein the write operation corresponds to a disk image that is locally stored in a first host computer. The disk image and a second disk image is updated in accordance with the write operation, wherein (i) the second disk image is locally stored on a second host computer that is networked to the first host computer, (ii) the second disk image serves as a back-up to the disk image, and (ii) the second host computer is configured to support the running of other virtual machines that access other disks images that (a) are locally stored on the second host computer, and (b) are further backed-up on at least a third host computer.
