A computer network, system and computer-readable medium for completing a backup job that was interrupted during a backup process is described. The computer-readable medium causes a processor to perform the steps of retrieving an object from one or more volumes stored in a client computer, determining whether the object is listed in a catalog, where the catalog comprises a partially backed up volume from a list of one or more volumes that still need to be backed up, determining whether the object is partially backed up if the object is listed in the catalog and writing the data contained in the object to one or more storage devices if the object is partially backed up or is not listed in the catalog.
