Abstract
Systems and methods for fault handling are presented. In one embodiment, a fault handling method includes: performing an information collection process, wherein the information collection process includes collecting information regarding guest operating system files of a virtual machine; performing a selective replication region identification process, wherein the selective replication region identification process includes identifying regions associated with a selective amount of the guest operating system files; and performing a replication process based upon result of the replication region identification process. In one embodiment, the selective replication region identification process includes identifying regions associated with files of interest. The selective replication region identification process can include identifying regions associated with temporary files. The information regarding files can include a list of regions used by the files after loopback mounting of a virtual disk file, a list of regions which have been modified on the virtual disk file and regions associated with metadata that has changed.
