How to recover the database in MS SQL Server

Recovery is the process of copying backed up data and putting recorded transactions into MS SQL Server data. Simply put, this is the process of retrieving the backup file and returning it to the database.

Database recovery can be done in two ways.

Method 1: Use T-SQL

The following syntax is used to restore databases.

 Restore database from disk = '' 

For example

The following command is used to restore the database named TestDB with a backup file named TestDB_Full.bak located at address D: if you choose to overwrite the current database.

 Restore database TestDB from disk = ' D:TestDB_Full.bak' with replace 

If you create a new database using this recovery command and there is no path or file to record history on the server above, use the command below. Make sure the path D: Data exists .

 RESTORE DATABASE TestDB FROM DISK = 'D: TestDB_Full.bak' WITH MOVE 'TestDB' TO 'D:DataTestDB.mdf', MOVE 'TestDB_Log' TO 'D:DataTestDB_Log.ldf'
