Database Mirroring step by step
Posted on 2009 under Mirroring | 2 Comments 25 Nov
Here is the detailed step by step implementation of Database Mirroring with screen shots. Note that I have shown here is a High Protection Mirroring scenario. Here we are setting up a synchronous operating mode.
Step 1
Create MirrorDB in the source database (called as Principal database), for which we are going to start mirroring.

Step 2
Create a backup of the MirrorDB in the source SQL Server (Principal database) & restore it in the destination server with the same name. Make sure to restore the database with NORECOVERY. The destination server MirrorDB is called as Mirror database.

Note that here I do not have a Witness server, & hence select “NO” for include Witness server option.

Step 6 Click on Start Mirroring to start the mirroring from Principal database to Mirror database.
Step 7 As you can see in the below screen shot, the status is, the databases are fully Synchronized.

Mirroring is a simple process & if failed we can easily reset it up, by restoring the latest backup of the source in the destination & reconfigure Mirroring.
