ABSTRACT:
A method according to one embodiment is performed in an environment wherein a plurality of backup hosts are connected to a plurality of virtual tape library servers (VTL servers) which in turn are connected to each of a plurality of disk library units (DLUs), each VTL server being adapted to receive tape storage commands, and in response to receiving a tape storage command, the respective VTL server accepts the tape storage command and responding as if the VTL server were the respective target tape storage device, and wherein data simultaneously streaming from the plurality of backup hosts is received by multiple of the VTL servers, where the multiple VTL servers receiving the simultaneously streamed data write to the same DLU.
