SQL Server中的数据库镜像

Question

I'm not a DBA but I hear that database mirroring is deprecated or about to be, I'm using SQL 2014, in my company they are using database mirroring, which is exactly the new version? it is something we can implement on SQL Server 2014 or we need to have a newer version installed? I want to convince people that database mirroring should be replaced.

Answer 1

AlwaysOn Availability Groups (AGs) are the replacement for Database Mirroring. You can stay on Mirroring on SQL 2014 if it works for you, but when you upgrade you should plan on migrating to AGs. If you're on Standard Edition, you can use Basic Availability Groups which have the same capabilities as Database Mirroring on Standard Edition.
