ABSTRACT:
A data processing system using a storage management server provides a method and apparatus for preserving consistency between a database back-up and a set of storage volumes. The system includes a plurality of client systems coupled to the storage management server. Primary and back-up copies of client files are stored within a set of attached storage volumes. The server contains a server database to maintain directory and reference location information linking the primary and back-up copies of the client files. The server periodically performs an incremental back-up of the server database to a database back-up. The server utilizes a reuse delay criterion to set selected storage volumes as pending volumes. Pending volumes are not eligible for reuse by the server, thereby preventing the server from overwriting these pending volumes and invalidating reference location information for the pending volumes stored in the database back-up. When the reuse delay criterion elapses, the pending volumes are classified as empty, making them eligible for reuse by the server.
