Feature Request: Option to disable application-consistent snapshot attempts on specific VMs (VBR Nutanix)

[daniel.lindner]

Description:

We are currently experiencing an issue where Veeam Backup for Nutanix AHV continuously attempts to create application-consistent snapshots through Nutanix Guest Tools (NGT), even when this is not possible or desired for certain VMs.

Regardless of configuration settings, Veeam still instructs Nutanix to attempt application-consistent snapshots, leading to a large number of warning or error messages from Nutanix (i.e., “application-consistent snapshot could not be created”). This behavior results in unnecessary log noise and false-positive alerts in our monitoring systems.

According to Veeam Support, there is currently no option to disable NGT application-consistency attempts per VM and to forcibly use crash-consistent snapshots only. The only configuration toggle (“Enable application-aware processing”) switches control to NGT, but does not suppress NGT’s internal consistency attempts.

  Case #07911575

Feature Request:

We would like to request an option (either globally or per protected VM) to:

• Disable application-consistent snapshot attempts, and
  Force crash-consistent snapshots directly, without triggering NGT to try application-consistency.

This would be particularly useful in environments where:

• NGT is installed but not fully configured,
  Application-consistent snapshots are not supported for technical or policy reasons, or
  Reducing Nutanix alert noise and backup job warnings is required.
  Such a feature would greatly improve backup reliability and operational visibility while maintaining flexibility for mixed workloads.

Environment:

Veeam Backup for Nutanix AHV (latest version)
Nutanix AOS (various clusters)
Veeam Backup & Replication integration in place

Thank you for considering this enhancement!

@daniel.lindner looks like we need to remove that bullet point in the HelpCenter link you referenced as we added NGT quiescence control a couple releases ago. Yes NGT quiescence can be disabled at the job level see https://helpcenter.veeam.com/docs/vbahv ... e-settings. If Veeam application-aware processing is disabled and NGT VSS is disabled in the backup job advanced settings for the job in question and it's still trying to run VSS snapshots you'd need to open a case with support.
