The issue you're experiencing with the
Restore-AzRecoveryServicesBackupItem cmdlet, where it's restoring all disks instead of only the OS disk, could be due to various factors. Let's go through some troubleshooting steps and considerations to help resolve this issue.
- Verify Recovery Point Selection: Ensure that the recovery point (
$rp) you are selecting is indeed the correct one and corresponds to a backup of the OS disk only. If the recovery point includes other disks, they might be restored as well.
- Check Parameters: Double-check the parameters provided in the cmdlet, especially
VaultId. Any mismatches or errors here could lead to unexpected behavior.
- Cmdlet Syntax and Version: Ensure that the syntax of the
Restore-AzRecoveryServicesBackupItemcmdlet is correct and that you're using a version of the Azure PowerShell module that supports the
-RestoreOnlyOSDiskparameter. It's a good practice to keep your Azure PowerShell module up to date.
- Azure PowerShell Module Version: If you are using an older version of the Azure PowerShell module, consider updating it. Newer versions may have bug fixes and enhancements that could resolve your issue.
- Documentation and Examples: Refer to the official Azure documentation for
Restore-AzRecoveryServicesBackupItem. Sometimes, the documentation contains specific examples or notes that might be relevant to your scenario.
- Alternative Approaches: If the script continues to not work as expected, consider alternative methods for restoring the OS disk. This might include using the Azure portal or different PowerShell cmdlets that provide more granular control over the restore process.
- Check for Known Issues: Look for any known issues or updates from Microsoft regarding the
Restore-AzRecoveryServicesBackupItemcmdlet. Sometimes, there might be known bugs or limitations that are affecting your process.
- Seek Support: If you're unable to resolve the issue, consider reaching out to Microsoft support or seeking advice from the Azure community, such as forums or discussion boards. Others might have encountered and solved similar issues.
Here is an example command structure for restoring only the OS disk. Make sure your command aligns with this structure:
Restore-AzRecoveryServicesBackupItem -RecoveryPoint $rp -StorageAccountName "<StorageAccountName>" -StorageAccountResourceGroupName "<ResourceGroupName>" -VaultId $Vault.Id -RestoreOnlyOSDisk
<ResourceGroupName> with your actual storage account name and resource group name.
