Abstract
Many archive and backup systems write multiple copies of at least portions of a single file to various archive or backup storage sessions. Such is the case where an initial backup occurs followed by incremental backups at various times after the initial baseline backup. The present invention simplifies the long-term administration of remote or archive storage by collecting multiple portions of the same files stored in different backup or archive storage sessions at different times into a single updated version of the file. This updated version may then be placed on backup or archive storage. The present invention identifies the various backup or archive sessions containing portions of the file of interest. It then retrieves these various portions and determines which of the portions are the most current version. The most current version of all portions are then assembled and coalesced into a single updated version. The system works with remote or local backup or archive storage and reduces the time necessary to retrieve information from a backup.
