How to Take Windows Server Backup Using PowerShell

Overview of Windows Server Backup

Windows Server Backup (WSB) is a feature that provides backup and recovery options for Windows server environments. You can use it to back up a full server (all volumes), selected volumes, the system state, or specific files or folders—and to create a bare metal backup that you can use for bare metal recovery. You can recover volumes, folders, files, certain applications, and the system state.

Windows Server Backup is designed for everyone who needs a basic backup solution (from small businesses to large enterprises), but even for small organizations or individuals who are not IT professionals.

How to Install Windows Server Backup Using PowerShell

Performing Windows Server backups is an important part of daily Windows Server management. Backup allows you to recover lost data from disaster scenarios such as hardware failure, software failure, human error, and computer virus.

To prepare for server backup, you need to install the Windows Server Backup feature first. After installation, you can access Windows PowerShell cmdlets for Windows Server Backup. To install this feature, using PowerShell is the easiest way.

1. Type powershell in the search box and right-click on the top result to run Windows PowerShell as administrator.

2. Then type Install-WindowsFeature Windows-Server-Backup and press Enter. Then wait until the installation process completes.

How to Configure Windows Server Backup by PowerShell Cmdlets

After installing Windows Server Backup on your server, you can use Windows PowerShell cmdlets for Windows Server Backup to automate and manage backups. The cmdlets for Windows Server Backup are contained in a Windows PowerShell snap-in. You need to import the PowerShell snap-in.

#1. Add the Windows Server Backup Cmdlet snap-in to Windows PowerShell

1. In Windows PowerShell prompt, type:

☞ add-pssnapin windows.serverbackup

2. To confirm that the snap-in was added, at the Windows PowerShell prompt, type:

☞ get-pssnapin

Once this is done, you are ready to start with the Server Backup cmdlets.

#2. Configure Windows Server Backup using PowerShell Cmdlets

The cmdlet descriptions and syntax of some Windows Server Backup cmdlets are provided below for reference. If you want to learn about all cmdlets, click here.

Add-WBBackupTarget:	Adds a backup target to a backup policy.
Add-WBBareMetalRecovery:	Adds items to a backup policy so that backups that use the policy can perform bare metal recoveries.
Add-WBSystemState:	Adds the system state components to the backup policy.
Get-WBBackupSet:	Gets backups for a server from a location that you specify.
Get-WBBackupTarget:	Gets backup storage locations that you specified as part of a backup policy.
Get-WBJob:	Gets the current backup operation.
Remove-WBBackupSet:	Removes backups from a target catalog, a system catalog, or both.
Remove-WBBackupTarget:	Removes backup storage locations from a backup policy.
Start-WBBackup:	Starts a one-time backup operation.
Start-WBFileRecovery:	Starts a file recovery operation.

I will show you how to starts a one-time backup operation by PowerShell cmdlets.

1. Run Windows PowerShell as administrator.
2. Type the following commands in order, and then press Enter after each command.

● The first command creates a new backup policy object and stores it in a variable named $Policy.    PS C:\> $Policy = New-WBPolicy

● This command adds the current system state options to the backup policy in the $Policy variable.    PS C:\> Add-WBSystemState $Policy

● This command adds the ability to perform a bare-metal recovery to the backup policy in the $Policy variable.    PS C:\> Add-WBBareMetalRecovery $Policy

● This command creates a new backup location object that contains the volume that has the drive letter E and then stores that object in the $BackupLocation variable.    PS C:\> $BackupLocation = New-WBBackupTarget -VolumePath "E:"

● This command adds the backup target based on the backup policy in the $Policy variable and the backup location in the $BackupLocation variable.    PS C:\> Add-WBBackupTarget -Policy $Policy -Target $BackupLocation

● This command specifies that the backup policy in the $Policy variable uses Volume Shadow Copy Service (VSS) copy backups.    PS C:\> Set-WBVssBackupOptions -Policy $Policy -VssCopyBackup

● This command starts the backup by using the backup policy in the $Policy variable.    PS C:\> Start-WBBackup -Policy $Policy

This example starts a backup by using new settings.

The observed attack appears to have implemented CVE-2022-41040 to gain privileged access and CVE-2022-41082 to perform remote code execution via PowerShell. 

Warning:  The Patch Tuesday, November 2022 reportedly fixes 69 Windows vulnerabilities. Among them, The CVE-2022-41040, and CVE-2022-41082 on Microsoft Exchange Server allows authenticated attackers to run Powershell command. And the attacker can potentially gain access to other resources via lateral movement into Exchange and Active Directory environments.
