This section will explain the step-by-step approach for the SQL Server restore database procedure using the BAK file. For this Restore Database demonstration, we use the adventure works 2017 .bak.
SQL Restore Database from BAK File
In this example, we will use the BAK file to Restore the SQL Database. The server does not have the AdventureWorks2017 database.
TIP: Please refer to Backup for creating a backup and Maintenance Plan for making regular backups in Sql Server.

As you can see, the MDF and LDF corresponding to the Adventure Works 2017 is not there in C Drive

We have an Adventure Works Backup file in our D Drive, and we will use this bak to restore a database.

Syntax of the restore Database from the backup file
RESTORE DATABASE DatbaseName FROM DISK = 'D:\Backups\BackupFileName.bak' WITH MOVE 'LogicalMDFFileName' TO 'location\MDFFileName.mdf', MOVE 'LogicalLDFFileName' TO 'location\LDFFileName.ldf'
Let me use the above syntax to restore the Adventure Works.
RESTORE DATABASE AdventureWorks2017 FROM DISK = 'D:\Backups\AdventureWorks2017.bak' WITH MOVE 'AdventureWorks2017' TO 'C:\Program Files\Microsoft ...........\DATA\AdventureWorks2017.mdf', MOVE 'AdventureWorks2017_log' TO 'C:\Program Files\Microsoft .........\DATA\AdventureWorks2017_log.ldf'
The query executes without any errors, and the db is attached successfully.

Now you can see the Adventure Works 2017

The above process has automatically added the MDF and LDF to the C Drive

If you don’t know the logical names, then use the Restore File System to retrieve the Logical Filenames.
RESTORE FILELISTONLY FROM DISK = 'D:\Backups\AdventureWorks2017.bak'
