Abstract
A method of creating backup files having less redundancy. The method creates a backup file by creating an overhead segment for each file that is to be backed up and creating a data segment containing the data that is to be backed up for each file. After creating the overhead segment and the data segment, the overhead segment is placed into an overhead stream data segment is stored in memory. The overhead segment is also positioned in the overhead stream with a pointer that identifies the data segment within the memory. For backups of subsequent servers or the same server at a later time, the backup software will create a separate overhead stream. However, a plurality of overhead streams may contain pointers to the same data segments such that redundant data segments do not need to be stored in a backup server.
