ABSTRACT:
When storing backup data in a primary memory, memory space is optimized by selectively storing objects in storage locations in the primary memory. Only objects which have not been updated since the latest backup are stored in a backup area of the primary memory, and only updated objects are stored in a data-base area. The data base accesses objects in the backup area. The backup area may be write-protected.
