Hi Guys, I'm currently preparing a LISTSERV installation and need some information regarding system integrity. Our current deployment scenario is as follows: Windows 2003. Two separate servers containing identical installations of LISTSERV with one server to act as the Primary, which will handle all LISTSERV traffic sitting behind a virtual IP address. The other server acts as a “Warm standby.” Somehow, I need to keep the standby server in sync with the Primary so that in the event of the Primary failing, we switch to the standby, with potentially little or no loss of data. The issue here is how do we keep the second server up to date? I'm going to write a separate component to copy LISTSERV’s file store from the Primary to the Secondary on a regular basis, but I wondered if anyone on this discussion list has already tackled the same issue, who may be able to help. I have checked the "Moving LISTSERV to a new server" document, which contains some useful information, but I wanted some opinions/experiences from anyone who might have actually done it. Thanks in advance, Kev Ward.
