Answer 2

.bak files are database backups. You can restore the backup with the method below:

How to: Restore a Database Backup (SQL Server Management Studio)

Answer 3

This will show you a list of database files contained in DB.bak:

RESTORE FILELISTONLY 
FROM DISK = 'D:\3.0 Databases\DB.bak' 

You will need the logical names from that list for the MOVE operation in the second step:

RESTORE DATABASE YourDB
FROM DISK = 'D:\3.0 Databases\DB.bak' 

and you have to move appropriate mdf,ndf & ldf files using

With Move 'primarydatafilename' To 'D:\DB\data.mdf', 
Move 'secondarydatafile' To 'D:\DB\data1.ndf', 
Move 'logfilename' To 'D:\DB\log.ldf'

Answer 4

You can simply restore these database backup files using native SQL Server methods, or you can use ApexSQL Restore tool to quickly virtually attach the files and access them as fully restored databases.

Answer 5

Instead of choosing Restore Database..., select Restore Files and Filegroups...

Then enter a database name, select your .bak file path as the source, check the restore checkbox, and click Ok. If the .bak file is valid, it will work.

(The SQL Server restore option names are not intuitive for what should a very simple task.)

Answer 8

1. Copy your backup .bak file in the following location of your pc : C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA
2. Connect to a server you want to store your DB
3. Right-click Database
4. Click Restore
5. Choose the Device radio button under the source section
6. Click Add.
7. Navigate to the path where your .bak file is stored, select it and click OK
8. Enter the destination of your DB
9. Enter the name by which you want to store your DB
10. Click OK

The above solutions missed out on where to keep your backup (.bak) file. This should do the trick. It worked for me.

Answer 9

Simply use

sp_restoredb 'Your Database Name' ,'Location From you want to restore'

Example: sp_restoredb 'omDB','D:\abc.bak'

Answer 10

Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example

RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO

In above Query you need to keep in mind about .mdf/.ldf file location. You might get error

System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)

So you need to run Query as below

RESTORE FILELISTONLY 
FROM DISK = 'D:\AdventureWorks2012.BAK'

Once you will run above Query you will get location of mdf/ldf use it Restore database using query

USE MASTER
GO
RESTORE DATABASE DBASE 
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH 
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF', 
NOUNLOAD,  REPLACE,  NOUNLOAD,  STATS = 5
GO

Answer 11

You can use node package, if you often need to restore databases in development process.

Install:
