Abstract
A host coupled to a storage system accesses secondary storage coupled to the storage system and to the host by determining if direct data access between the storage system and the secondary storage is operational, the host forwarding commands to the storage system to directly access the secondary storage in response to direct data access between the storage system and the secondary storage being operational, and the host generating modified commands to cause the host to directly access the secondary storage in response to direct data access between the storage system and the secondary storage not being operational. The secondary storage may be a cloud storage. The secondary storage may be a tape emulation unit. The host may directly access data of the tape emulation unit by accessing a storage device of the tape emulation unit. Commands on the host may be modified by a drivers layer on the host.
