Abstract
Computer implemented methods, computer program products and computer systems synchronize copies of a virtual disk. A record of blocks that are modified during an access session of a copy of the virtual disk is maintained. For each partition of the virtual disk, a file system level indication of currently relevant blocks is obtained. Only those blocks that were modified during the access session and are currently relevant are copied to at least one additional copy of the virtual disk.
