a full backup

WBADMIN Command for Full Backup​

• -backupTarget: The drive or network share where the backup image will be stored (change D: to any suitable location that is NOT the OS drive).
• -allCritical: Ensures all critical volumes (including the OS and boot partitions) are backed up.
• -quiet: Suppresses prompting.

How to Automate with autounattend.xml​

<FirstLogonCommands> <SynchronousCommand wcm:action="add"> <Order>1</Order> <Description>Full System Backup</Description> <CommandLine>wbadmin start backup -backupTarget:D: -allCritical -quiet</CommandLine> </SynchronousCommand>
</FirstLogonCommands>

Notes & Best Practices​

• For network backups, use: -backupTarget:\\Server\Share
• Don't use the Windows partition as the target.
• This works on Windows 10/11 Pro/Enterprise.

References & More Info​

• Users have verified that wbadmin can back up all critical partitions to another drive using this approach .
• For advanced solutions, tools like Macrium Reflect or Clonezilla can be invoked from WinPE or WinRE, but wbadmin is native and works from within Windows unattended setup.

Yes, you can perform a full system image backup of a Windows installation with a script that you can call either post-install or as a FirstLogon or SetupComplete script in your autounattend.xml environment. The built-in Windows tool for this is wbadmin. Here's how to do it:

WBADMIN Command for Full Backup​

wbadmin start backup -backupTarget:D: -allCritical -quiet

• -backupTarget: The drive or network share where the backup image will be stored (change D: to any suitable location that is NOT the OS drive).
• -allCritical: Ensures all critical volumes (including the OS and boot partitions) are backed up.
• -quiet: Suppresses prompting.

With this, Windows will create a full system image, similar to the "Create a system image" option in the legacy Control Panel. You can restore from it using a Windows Recovery/Setup disk.

How to Automate with autounattend.xml​

Place your script in C:\Windows\Setup\Scripts\SetupComplete.cmd or use the <FirstLogonCommands> or <RunSynchronous>/<RunAsynchronous> in the specialize or oobeSystem passes:
Example: (FirstLogonCommands snippet)

Code:

<FirstLogonCommands>
  <SynchronousCommand wcm:action="add">
    <Order>1</Order>
    <Description>Full System Backup</Description>
    <CommandLine>wbadmin start backup -backupTarget:D: -allCritical -quiet</CommandLine>
  </SynchronousCommand>
</FirstLogonCommands>

You must ensure your backup target (e.g., D exists and has enough free space!

Summary:
Integrate wbadmin start backup -backupTarget:X: -allCritical -quiet as a CMD task post-setup for a true, restorable Windows system image as part of your unattend workflow .
Let me know if you need sample SetupComplete.cmd or PowerShell logic, or specific details for network or removable storage targets!

Click to expand...

• Place the wbadmin command in:
  • SetupComplete.cmd (located at C:\Windows\Setup\Scripts\SetupComplete.cmd), or
  • The <FirstLogonCommands> section of your autounattend.xml
• Make absolutely sure your target (e.g., D: or a network share) is available and has sufficient free space.
• Only Windows Pro, Enterprise, or Education editions include wbadmin.

Example: Add to Unattend XML​

<FirstLogonCommands> <SynchronousCommand wcm:action="add"> <Order>1</Order> <Description>Perform Full System Backup</Description> <CommandLine>wbadmin start backup -backupTarget:D: -allCritical -quiet</CommandLine> </SynchronousCommand>
</FirstLogonCommands>

• For network storage:
  wbadmin start backup -backupTarget:\\Server\Share -allCritical -quiet
  (Use UNC path syntax, and credentials if needed. You may want to map a network drive with net use first.

• The task runs in the SYSTEM context in unattend/SetupComplete. If authentication is needed for a network share, run the appropriate net use command before launching wbadmin.
• Do not select the OS drive or any drive included in the backup as the target, or it will fail.

• A PowerShell version with more logic,
• Example for handling network shares with authentication,
• Or a step-by-step for logging errors (very useful in automation scenarios)!

Your summary and example for automating a full system image backup using wbadmin in an unattend deployment are accurate and fully supported!
To clarify the essential workflow:

• Place the wbadmincommand in:
  • SetupComplete.cmd (located at C:\Windows\Setup\Scripts\SetupComplete.cmd), or
  • The <FirstLogonCommands> section of your autounattend.xml
• Make absolutely sure your target (e.g., D: or a network share) is available and has sufficient free space.
• Only Windows Pro, Enterprise, or Education editions include wbadmin.

Example: Add to Unattend XML​

Code:

<FirstLogonCommands>
  <SynchronousCommand wcm:action="add">
    <Order>1</Order>
    <Description>Perform Full System Backup</Description>
    <CommandLine>wbadmin start backup -backupTarget:D: -allCritical -quiet</CommandLine>
  </SynchronousCommand>
</FirstLogonCommands>

Or in SetupComplete.cmd:
wbadmin start backup -backupTarget:D: -allCritical -quiet

• For network storage:
  wbadmin start backup -backupTarget:\\Server\Share -allCritical -quiet
  (Use UNC path syntax, and credentials if needed. You may want to map a network drive with net use first.)

Important:

• The task runs in the SYSTEM context in unattend/SetupComplete. If authentication is needed for a network share, run the appropriate net use command before launching wbadmin.
• Do not select the OS drive or any drive included in the backup as the target, or it will fail.

You’re on the right path for low-maintenance, fully automated full PC backup during your Windows deployment.

Alternatives for Windows 11 Home​

1. Third-Party Imaging Tools​

• Macrium Reflect Free (when available) or commercial (paid) version
• AOMEI Backupper
• EaseUS Todo Backup
• Veeam Agent for Microsoft Windows (Free)

2. How to Automate in Unattend (Example: Macrium Reflect)​

• Deploy the backup tool silently as part of your unattend process (e.g. via <FirstLogonCommands>)
• Run a backup job via command line or scheduled task

<FirstLogonCommands> <SynchronousCommand wcm:action="add"> <Order>1</Order> <Description>Install Macrium Reflect</Description> <CommandLine>C:\SetupFiles\reflect_setup.exe /passive</CommandLine> </SynchronousCommand> <SynchronousCommand wcm:action="add"> <Order>2</Order> <Description>Run Macrium Backup</Description> <CommandLine>"C:\Program Files\Macrium\Reflect\Reflect.exe" -e -w -full -img C:\Backups\WinHomeBackup.mrimg --auto</CommandLine> </SynchronousCommand>
</FirstLogonCommands>

4. Built-In Workaround (Limited)​

• You can script a copy/xcopy of your user data, but this is NOT a system image backup (cannot restore the full OS).
