What you are describing is "somewhat" feasible but the task of taking archive log copies onto cd then over to the other machine sounds like a potential operational nightmare.

If your active database has much volume at all it sounds like something to avoid. Can you look at getting some kind of network connectivity for the remote location? Received on Tue Jan 02 2007 - 15:53:48 CST
