We are running 6.1 on NTique servers. We have a secondary server and use a product from Computer Associates called SurviveIT. It does real-time sync of data from the primary to the secondary. It can be configured to automatically have the secondary take over for the primary based on ping responses etc. Or it can be done manually. It has been in place for almost 5 years and never needed it. In January - two drives went down in the primary's Raid 10 at the same time. Talk about a cross your fingers moment! I just changed the IP address of the backup server, renamed the backup to the same name as the primary and rebooted - everything was saved in tack. Didn't find anything out of place or missing.
After getting production backup and running, during troubleshooting of the primary - I found that only one drive was actually bad. But when it failed the controller took both drives on that chain offline.
Regarding VM: Have you done any benchmarks on your network speed when using virtualization? It seems to take quite the performance hit when I tested transfers to and from a virtualized host using VBox. It didn't matter what host OS was being used either. The numbers I found posted for VMWare were only slightly better. My question is do you actually see a performance difference from the end users point of view when running big reports or other aspects of Vantage.

Subject: [ok] [Vantage] Re: Backup server (Vantage version 6.1)
VMware is indeed great. But here is what I'm doing.
I bought a thousand dollar server (with everything including os license
it was more like 2 thousand). I installed Vantage on it, and have daily
scripts that back up the production server and populate the cheapie
server.
This server not only servers as a test database (refreshed daily), but
also as a test of the backup process (what better way to test then to
do a restore?) and as a oh crap main server is down lets limp along on
this one server.
Ofcourse I do backups to tape as well, and to another disk, but this
way I know I'm ready for near anything.
