Abstract
A backup and restore system includes a work item server for restoring multiple work times simultaneously. The work item server assigns each work item to a respective trail queue based upon the commonality of the volumes on which the work items are stored. The work item server allocates drives to the trail queues for restoring multiple work items simultaneously. The trail queue have drives assigned for work items in that trail queues to use during a restore. The trail queue has a concurrency defined to predetermine the number of simultaneous work items can run that are associated with the trail queues. Drives can be allocated to the trail queues for executing work item restores associated with the respective trail queues until a predetermined trail queue concurrency is reached.
