When restoring an SQL database through SQL Server Management Studio (SSMS), you may encounter several issues. These problems may result due to data corruption, data loss, or similar reasons. Here is a glance at some of the most common issues and the solutions to avert them.

1. Database in use

One common problem is the Error Message: Restored failed for Server ‘XYZ’ (Microsoft.SqlServer.SmoExtended), ‘Database in Use’. Here are some of the possible reasons behind this Error.

  • You are trying to access the database which is already in use
  • You have opened multiple windows in the SSMS when using it for database restoration
  • Insufficient permission to access the database
  • Issue with corrupted backup file
  • Disk space issue

Before trying the solutions, make sure to close any already opened SQL Query window. Most probably, it will resolve your issue. If the problem prevails, here are some of the SQL restoration solutions that you can try out:

a. Tick the option ‘Close existing connections to destination database’

For this, using the SSMS GUI would be preferable.

Write For Us Technology

  • Under the Object Explorer panel on your left, right-click Databases

  • Click Restore Database next.

  • In the resulting Restore Database dialog box, click General.
     
  • Select the database that you want to restore.
  • Click ‘Options’, the third choice on the left side of the dialog box.

  • Look for Server Connections, the third section from the top

  • Click Close existing connections to destination database.
  • Click OK to proceed with the database restoration.

b. Switch to Single User Mode

To make sure that no other user is accessing the database, you can switch SQL Server to ‘Single User Mode’. After the completion of the database restoration process, you may set the SQL server again to multi user mode. Type the following commands on your SQL Query Builder.

USE master;

GO

ALTER DATABASE dbname

SET SINGLE_USER

WITH ROLLBACK IMMEDIATE;

ALTER DATABASE dbname

SET MULTI_USER;

GO

The image below shows one example of the usage of these commands for SQL repair.

Running this command will disconnect all the existing users connected with the database. Check for the below acknowledgment in the messages panel of SSMS for successful completion of these commands

c. The use of WITH RECOVERY

One more SQL repair solution to fix the failed restoration of the database in use is to use WITH RECOVERY.

For this, click New Query in SSMS and enter the below command in the resulting window:

  • RESTORE DATABASE dbname WITH RECOVERY;
  • Click Execute from the toolbar on the top of the screen to execute the command
  • Disconnect the instance and connect again.

You will observe a vanished “Restoring” mark from the database.

d. Restart the SQL Server Service

If all your methods succumb to restoring your database, you may opt to restart the SQL service. This will also disconnect all the users from the database. Here are the easy steps for SQL repair in this situation.

  • On the left bottom corner of your desktop, click start à SQL Server Configuration Manager
  • In the left panel of the resulting window, click SQL Server Services
  • In the right panel corresponding to SQL Server Services, right click SQL Server (SQLEXPRESS) or a similar instance
  • Click Stop and then click Start
  • Click to OK.

This will restart your SQL Service.

2. Media errors during backup restoration

When you want to recover a corrupted backup file, it may lead to several media errors that such as 3241, 3242, or 3242, resulting in a failed restoration. The corrupted backup file may be due to a malware attack or a problematic hardware. Here are the necessary steps to resolve these issues.

1. Find out the reported hardware errors in the Windows Event Viewer logs

  • If you find an error, take the requisite action to fix them.
  • For example, resolve the issue with network connectivity, upgrade the firmware, etc.

2. Enable the option for Backup CHECKSUM to verify the validity of the backups and ensure that they are corruption-free.

3. Backup or restore operations using third-party backup applications fail

Often, users seek the help of a third-party SQL database repair toolto restore their database. In certain cases, where you are not using a reliable brand such as Stellar, they are likely to create problems in SQL repair. To solve this issue, SQL server extends the facility of Virtual Backup Device Interface (VDI) tool.

This Application Programming Interface (API) allows the vendors to integrate SQL Server with their product. The API makes the software ready to support the database restore and backup operations.
