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.
