You could do inline tape copies and send 1 each to the other sites. You can ftp the image info across the LAN and not have to import.
Tech Doc 266673 was the doc detailing how to move image data between master servers.

Arg again! No SAN/fiber switches here, direct-attached (hence why the master-server is what I am looking at). > > At site A, employ a Media server (call it media-dual) that is > controlled by the master at Site B.

I thought of this as well, but for other reasons, having a master control its own site actually turned out to be the best and having the clients from the other backup to it (aka cross-site) > > For critical information, back up the info with the master-B via media-dual. > Back it up to the drives at site A in case you need to do a restore or > create a dssu at site A for these backups.

A lot of this though stems from the fact I cannot do what I really want to do, it is almost if the _real_ work around is just have the client backup the data twice (if you wanted to be protected from a dual-site failure?) clientA -> site B clientB -> site C Justin. _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
