ABSTRACT:
The present invention provides a method, a system and code for backing up information on a storage system, for example, a disk system, connected to a storage area network. The host or server system off loads the task of backing up its data to the storage system that stores the data. In an exemplary embodiment a server sends an E-copy command to a disk system. Next, the disk system finds an available back-up device, for examples a tape or DLT library, and then backs-up the information indicated in the E-copy command to the back-up device. A user interface is provided so that one or more path groups, comprising at least a target port and an initiator port, on a disk system may be designated.
