Abstract
A database management system and associated methods for parallelizing file archival and retrieval in an extended database management system. The system includes a set of copy agents that selectively acquire the backup tasks from a copy queue, and a set of retrieval agents that selectively acquire the restore tasks from a restore queue. The chances of contention between any two copy agents or any two retrieve agents acquiring the same copy or restore task is significantly minimized. Once specific copy agents are assigned backup tasks, the backup process is implemented to determine the optimal way to write the backup files to one or more targets, in parallel. In addition, the present system enables the efficient and expeditious retrieval of the desired files without having to search all the targets.
