1. In a data processing system, a method for creating multiple copies of a data set in storage pools having multiple destinations, comprising:
- storing copies of the data set in locally attached server storage pools with respect to a server;
storing copies of the data set in client storage pools connected by a first type of network connection to a client;
receiving a request in the server from a client storage agent in the client to set up a storage session;
creating a session in the server to monitor the activities of a copy operation;
establishing, by the server, a location of the client storage pools;
obtaining, by the server, mount points for volumes in the server and the client storage pools storing the data subject to the copy operation;
reporting, by the server, results of creating the storage session to the storage agent;
transferring the data set once from the client to the server over a second type of network connection; and
,storing, by the server, copies of the data set in the server storage pools using the obtained mount points so that data is written to the client and server storage pools.
