Hi All,
Currently I am having a 2 SQL 2008R2 databases in a database mirroring configuration. Every quarterly we would isolate the Principal from the Mirror server. And during this isolation period, some data changes would be made to the Mirror server.
After these changes were made on the Mirror server, we would connect them back in the mirror configuration. In order to ensure that the changes in the Mirror server is not synchronized to the Principal server during this reconfiguration, we would take a full backup of the Principal server and restore to the Mirror server.
I find it time consuming when I have to perform full backup of the Principal server and restore to the Mirror server during the reconfiguration.
Is there any better way to ensure that the Mirror server changes are not sync to the Principal when reconnecting them back in mirror configuration? Or if I upgrade to SQL 2012, will the Always-On feature allow me to ensure that data syncing is 1 way ie from Principal to Mirror only?
Thanks
