ABSTRACT:
A computer system and method for performing restore operations. A computer system includes one or more hosts. At least one host includes a backup agent. In response to a request to restore a file to a first host, a backup component identifies copies of portions of the file stored on a second host, retrieves the copies, and restores the file on the first host from the copies. The backup component maintains a catalog of entries corresponding to copies of portions of files stored on the hosts. In response to a request to restore the file to a first host, the backup component queries the catalog to identify one or more candidate locations where copies of portions of the file have been stored. The first and second hosts may be the same. The backup component may be located on a host or on a backup server.
