[SOLVED] Azure windows VM extensions are provisioning failed state VM agent is "Ready" but Backup failed at VM running State GuestAgentSnapshotTaskStatusError

Azure windows VM extensions are provisioning failed state VM agent is "Ready" but Backup failed at VM running State GuestAgentSnapshotTaskStatusError

Backup is failing for Azure VM with error - GuestAgentSnapshotTaskStatusError Azure Backup service could not communicate with the VM Agent for triggering a snapshot (to take a backup), because the VM Agent might be in an inconsistent state. Guest Agent is in a Ready state, however, the backup extension is in a failed state. the issue is that the VM agent is ready but the VM extensions are in provisioning failed state they are as follows 1.AzureDiskEncryption 2.enablevmaccess 3.MicrosoftMonitoringAgent 4.WindowsAgent.AzureSecurityCenter

Solution

Solution : You would need to re-install the Backup extension. Please follow the below action plan:

Take Backup of whole Registry then use below steps : 1.Login to the affected machine.

Open Registry Editor.
Remove VMSnapshot registry keys at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Azure\HandlerState
Remove or rename VMSnapshot Plugin Folders at C:\Packages\Plugins.
Now, open command prompt as admin and run below commands to force the extension installation :

REG ADD "HKLM\SOFTWARE\Microsoft\BcdrAgent" /v IsProviderInstalled /t REG_SZ /d False /f
REG ADD "HKLM\SOFTWARE\Microsoft\BcdrAgentPersistentKeys" /v IsCommonProviderInstalled /t REG_SZ /d False /f 6.Restart the Service "WindowsAzureGuestAgent". 7.Trigger a manual backup. As a part of backup, extension will be re-installed automatically.
