Abstract:
Recovery points can be used for replicating a virtual machine and reverting the virtual machine to a different state. A filter driver can monitor and capture input/output commands between a virtual machine and a virtual machine disk. The captured input/output commands can be used to create a recovery point. The recovery point can be associated with a bitmap that may be used to identify data blocks that have been modified between two versions of the virtual machine. Using this bitmap, a virtual machine may be reverted or restored to a different state by replacing modified data blocks and without replacing the entire virtual machine disk.

Claim (Index 11):
A system for reverting to an earlier version of a virtual machine, the system comprising:\n a filter driver implemented in computer hardware, the filter driver configured to:\n receive an identification of a recovery point of a virtual machine; \n initiate the virtual machine in a first state, the first state more recent than a state corresponding to the recovery point; \n access a bitmap corresponding to the recovery point; \n identify a set of data blocks to retrieve from a secondary storage system based at least in part on the bitmap, wherein the set of data blocks correspond to data blocks that differ in content compared to corresponding data blocks of a virtual machine disk of the virtual machine; \n initiate a data block retrieval process to retrieve the set of data blocks from the secondary storage system; \n receive an input/output command that references a data block from the set of data blocks that has yet to be retrieved; and \n prioritize the data block for retrieval over remaining data blocks from the set of data blocks.
