A Selective Dataset Backup Scheme for the DRCS Central Computer
J. C. Gwatking · Defense Technical Information Center (DTIC) · 1978
This report describes the approach taken by the DRCS Computing Centre to maintaining adequate backup facilities while the quantity of data stored on-line continues to increase. The aim is to provide the required level of service to users with minimum operational overhead. This has been accomplished by the development of a software system to control the backup process. The basis of this scheme is the ability to determine which datasets have been altered and to select only these for backup.
