Application aware snapshot failing when Azure defender cloud extension is enabled

[ajmayala85]

Hello Veeam Forum,

Veeam Support - Case # 07068336 - Crash-consistent snapshot of vm has been created. Failed to deploy the Windows VSS agent

We have some Azure VM machines that has SQL Server installed inside those machines. We run snaps/backups with the feature "application aware snapshots" enabled on those SQL machines.

The application aware snapshots were working correctly until the Azure Defender Cloud extension was enabled, the Azure defender for SQL service was enabled on the SQL servers, after which the consistent snapshots began to flag the following warning:

Crash-consistent snapshot of VM has been created. Failed to deploy the Windows VSS agent

On the Veeam Azure logs extract shows the following:

[04.01.2024 17:19:16.411] 79 (1) Unable to run PowerShell script, another is already in progress (code: 'Conflict', message: 'Run command extension execution is in progress. Please wait for completion before invoking a run command.', VM

The snaps works from time to time, when the consistent snap works it take 1 hr 51 mins to complete and the posterior snaps ends with the warning Crash-consistent snapshot of VM has been created. Failed to deploy the Windows VSS agent.

We have tried disabling Azure defender for SQL service but problem persist

Any ideas?

Best regards

Alan
