Selective Dataset Backup Scheme for the DRCS Central Computer.

摘要

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. (Author)
