Configuring the mirroring
Step1: Take the full backup of principal Database.
BACKUP DATABASE [Database_Name] TO DISK = 'Path of.bak';
Step2: Take the transaction log backup of Principal database.
BACKUP LOG [Database_name] TO DISK = 'Path of .trn';
Step3:If database is in recovery mode then Remove the recovering of mirror database.
Restore database [Database_name] with recovery
Step4:We have the backup folder shared on the Principal Server and you can access it from the Mirror Server
Step5:Restore the full backup to the Mirror server with the NORECOVERY option.
RESTORE DATABASE [Database_Name] FROM DISK = N'\\Principal\Backup\Backup.bak' with norecovery
Step6: Restore log backup also with the NORECOVERY option.
RESTORE LOG TestMirror FROM DISK = N'\\Principal\Backup\Backup.trn'
WITH FILE = 1, NORECOVERY, NOUNLOAD, STATS = 10;
Step7:configure Database Mirroring From the Principal server.
Right click the database and choose "Tasks"--> "Mirror" or choose "Properties"-->"Mirroring".
Step8:Click the "Configure Security" button and click "Next >" if the Configure Database Mirroring Security Wizard intro screen appears.
Step9:Select "No" for "Do you want to configure security to include a witness server instance".
Because we are configuring mirroring in Sychronized mode with High safty.
Then click "Next>" to continue the process.
Step10:Configure the Principal Server Instance.
with creating our endpoint communicate over the network. We will name it Mirroring with a Listener Port of 5022.
Click the "Next >" button to continue.
Step11: Configure the Mirror server instance.
click the "Connect..." button then select the mirror server.
Click the "Next >" button to continue.
Step12:Service Accounts
leave the fields blank all the server instances use the same domain account.
Click the "Next"
Step13:Complete the wizard screen that summarizes what we just configured.
Click the Finish.
Step14: Click the on Start mirroring.
If everything turned out right, Database Mirroring has been started successfully and we are fully synchronized.
1.Remove the mirror configuration.
2.Mirror Database set with Recovery.
Test Plan:
Step1: Take the full backup of principal Database.
BACKUP DATABASE [Database_Name] TO DISK = 'Path of.bak';
Step2: Take the transaction log backup of Principal database.
BACKUP LOG [Database_name] TO DISK = 'Path of .trn';

Backout plan:
1.Remove the mirror configuration.
2.Mirror Database set with Recovery.
1.Verify, Both servers should be listening on the same port.
SELECT type_desc, port
FROM sys.tcp_endpoints;
2.To verify, Database mirroring should be started on both servers.
SELECT state_desc
FROM sys.database_mirroring_endpoints;
The state_desc column on both the Principal and Mirror server should be started.
3.Verify to ROLES should be the same on both the Principal and Mirror Server.
SELECT role
FROM sys.database_mirroring_endpoints;
