In this article, I describe some steps a DBA can take to check for mirroring on SQL Server, give a status of the mirroring state and some options for resolving any problems with the transaction log that might be caused by Database Mirroring.
This tip outlines a test environment and then walks through the process of setting up Database Mirroring. This includes the configurations, backups, restores and verification process.
