Abstract: The present disclosure provides for efficiently creating a full backup image of a client device by efficiently communicating backup data to a backup server using a change tracking log, or track log. A present full backup image can be created using a track log that is associated with a previous full backup image. The client device can determine whether files, which were included in the previous full backup image, have or have not changed using the track log. The client device can transmit changed file data to the backup server for inclusion in the present full backup image. The client device can also transmit metadata identifying unchanged file data to the backup server. The backup server can use the metadata to extract a copy of the unchanged file data from the previous full backup image for inclusion in the present full backup image.

Abstract: In some embodiments, during a restore operation, a restore program executes in a restore environment on the restore system. The restore program may create a client environment to which a backed up client may be restored, which may include one or more client volumes. The restore program may create a directory structure to restore shadow copy component files, and may mount one or more of the client volumes to the directory structure. The shadow copy component files may be restored to the restore volume(s), and the files restored to directories that are beneath a mount point in the directory structure are restored, through the mount, to the client volume(s).
