  • Virtual machine aware replication method and system
    Patent number: 10162722
    Abstract: A method for replicating a virtual file system of a virtual machine. The method includes accessing a host file system usage map of a host machine that indicates active blocks out of a plurality of blocks of the host file system, and accessing a virtual file system usage map of a virtual machine that indicates active blocks out of a plurality of blocks of the virtual file system. A merged usage map is generated from information of the host file system usage map and the virtual file system usage map that identifies active blocks of the host file system associated with the virtual file system. The virtual file system is then replicated at a replication destination in accordance with the merged usage map.

  • System and method for optimizing mirror creation
    Patent number: 9934108
    Abstract: Embodiments of the present invention are directed to a method and system for optimizing mirror creation. The method includes receiving, within an electronic system, a request for creating a mirror of a portion of a volume and accessing a data structure comprising information about a plurality of regions of the volume. The method further includes determining a plurality of regions comprising non-zeros of the volume based on the data structure and copying only the plurality of regions comprising non-zeros to create the mirror.
