If you told someone in the distributed world that you had another server that was going to access a distributed server's LUNs and copy them while the server was running, you would be laughed at. It's the same problem, just a different disk technology. So if you can't ever bring down the server, then your DR strategy has to be the same as it was when it was on Solaris. That is, you install a 'starter' Linux and use that to restore your backups. The only thing that would be different is the location of the starter Linux. Forget about DDR in that context except as (maybe) the source of the starter Linux itself. Alan Altmark z/VM Development IBM Endicott
