Can you use PowerShell script to restore SQL database from backup

The answer is yes. As an automated Windows scripting tool, PowerShell provides a variety of cmdlets, among which Restore-SqlDatabase can be used to restore database from backup.

Here's a basic tutorial and simple sample that can be used for one or several databases. If you need an easy way to restore more (or all) databases on SQL Server, you can also consider using professional SQL Server backup software.

Restore SQL database from backup using PowerShell script

First, using PowerShell script to restore a database assumes that you have created a backup file in .bak format. For the backup method, you can refer to PowerShell script to backup multiple SQL databases.

With the previously created backup files, you could follow this guide to restore SQL databases.

Preparations: Import the required cmdlet

1. Search for “powershell” in Windows search bar, and run Windows PowerShell ISE as administrator.

Tip: PowerShell ISE is basically an upgraded version of PowerShell. It adds a notepad function allowing you to freely select and delete characters from the commands you type. You can also save the script as executable ps1 files.

2. Then you need to import the appropriate cmdlet. click New Script, type the following command and run it:

Import-Module SQLPS –DisableNameChecking

Note: If you get an error when importing the module, indicating that SQLPS is not trusted, try executing Set-ExecutionPolicy RemoteSigned first, and then re-importing the cmdlet.

import cmdlet

Restore one or several SQL databases from backup

The basic PowerShell script to restore SQL database is:

Restore-SqlDatabase -ServerInstance Server/InstanceName -Database DatabaseName `

-BackupFile "Path\FileName.bak" –ReplaceDatabase

Fill in your own information and run the command, then the specified database will be restored from the bak file. Here my example is:

Restore-SqlDatabase -ServerInstance Desktop-J899PPM -Database Date_1 `

-BackupFile " C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup\Date_1.bak" –ReplaceDatabase

*To customize the operation further, you can check this Microsoft page to learn more parameters of Restore-SqlDatabase.

Restore multiple SQL databases from backup easily

It may not be difficult to restore one or two SQL databases from backup. But if you want to recover numerous or all databases of an instance, you may need to use very complex scripts, whether in SSMS, command line or PowerShell.

If you are not adept at this and are fed up with repeated failures due to minor mistakes, using professional database backup & restore software is also a good way to go.
