USS Backstore

The CA Vtape USS Backstore feature utilizes z/OS UNIX System Services (USS) for reading and writing Virtual Volumes during Recall and Externalization. USS Backstore supports any USS file systems but is primarily intended for use with Network File Systems (NFS).

USS Backstore seeks to augment the Backstore engine to allow a copy of a Virtual Volume to be written to a USS file system server. A NFS server, while not required, can be a data de-duplication and or replication device.

USS Backstore will enable:

Access to less expensive disk
Tapeless implementations
Access to data de-duplication and replication devices to conserve network bandwidth

USS Backstore requires an active TCP/IP stack, USS, and the z/OS NFS Client running on your zOS/390 system. If necessary, refer to IBM's zOS/390 documentation regarding how to install or setup TCP/IP, USS, and the NFS Client on your system.
