Embodiments of the present invention comprise a method and apparatus for performing data backup from multiple nodes of a computer network. In one or more embodiments, the method of performing a data backup from multiple nodes of a computer network comprising generating a control message within a control node and, in response to the control message, enabling two or more nodes of the multiple nodes to access a tape drive concurrently.

A method, apparatus, and computer program product for implementing affinity based allocation for storage implementations employing deduplicated data stores is disclosed. According to an embodiment of the present invention, a backup manager determines if information associating a data source with a first data target of a plurality of data targets has been established. The first data target is a deduplication data store and the information associating the data source with the first data target indicates an increased likelihood of at least some information stored on the data source is already being stored on the first data target prior to performing a backup. If information associating the data source with the first data target has been established, the backup manager stores a set of data on the data target.

Method and apparatus for allocating resources among backup tasks in a data backup system is described. One aspect of the invention relates to managing backup tasks in a computer network. An estimated resource utilization is established for each of the backup tasks based on a set of backup statistics. A resource reservation is allocated for each of the backup tasks based on the estimated resource utilization thereof. The resource reservation of each of the backup tasks is dynamically changed during performance thereof.

A method and apparatus for routing a data stream through a plurality of data movers independent of a network interface type is provided. In one embodiment, the method for routing the data stream to a destination with indifference to network interface type includes segregating the data stream into a plurality of data blocks at an application layer, wherein the plurality of data blocks are to be routed to a destination through the plurality of data movers and coordinating data path selection for communicating the plurality of data blocks to the plurality of data movers over a plurality of data paths.

Techniques for host to host transfer of media and the use of persistent reservation to protect media during host to host transfer is disclosed. Exemplary embodiments may be realized as methods and systems for transferring a sequential media loaded in a drive from a first host to a second host without physically unloading the media. The first host may have a persistent reservation or non-persistent reservation of the drive. Likewise, the second host may have a persistent reservation or non-persistent reservation of the drive. Logical unload, logical load and preemption commands are utilized as is error recovery from a failed reservation.
