VMCE Application-Aware Processing and Guest OS Interaction 3

Question 1

If application-aware processing fails in a Veeam backup job and 'Require successful application-aware processing' is NOT enabled, what is the default fallback behavior?

Accepted Answer

Veeam falls back to creating a crash-consistent backup of the VM and logs a warning in the job report

Answer

The entire backup job fails immediately and no backup data is written to the repository

Answer

Veeam retries application-aware processing indefinitely until it eventually succeeds

Answer

Veeam skips the affected VM entirely and continues processing remaining VMs in the job

Question 2

How does Veeam handle Active Directory when performing application-aware processing on a Windows domain controller?

Accepted Answer

Veeam uses the Active Directory VSS writer to create an application-consistent snapshot of the AD database (NTDS.dit)

Answer

Veeam uses the Windows Server Backup API to create a system state backup of Active Directory

Answer

Veeam requires the domain controller to be in Read-Only Domain Controller (RODC) mode for consistent backups

Answer

Veeam skips Active Directory VSS processing and relies on crash-consistent backups for all domain controllers

Question 3

A Veeam backup job is experiencing VSS errors on a VM running SQL Server. What is the most appropriate first troubleshooting step?

Accepted Answer

Check the Windows Application event log on the guest VM for VSS errors and verify SQL Server VSS writer status using vssadmin

Answer

Reinstall Veeam Backup & Replication on the backup server to refresh VSS components

Answer

Increase the backup job's network bandwidth throttling settings to reduce load on the guest

Answer

Upgrade the VM hardware version in VMware vSphere to resolve compatibility issues

Question 4

What is the significance of a VSS writer showing a 'Failed' state when running 'vssadmin list writers' during Veeam backup troubleshooting?

Accepted Answer

A VSS writer in 'Failed' state means that writer's application could not be properly quiesced, blocking an application-consistent backup

Answer

A 'Failed' state means the VM snapshot could not be created at the hypervisor level

Answer

A 'Stable' state means the application-aware processing operation is currently in progress

Answer

VSS writer states are informational only and have no direct impact on Veeam backup consistency

Question 5

When Veeam performs application-aware processing on a VM hosting multiple SQL Server instances, what permission requirement applies?

Accepted Answer

The guest OS credentials must have sysadmin rights on all SQL Server instances to process transaction logs for each

Answer

A separate Veeam backup job must be created for each individual SQL Server instance

Answer

Only the default SQL Server instance is processed; named instances require a Veeam Agent installation

Answer

SQL Server instances must use Windows Authentication only; SQL authentication is unsupported by Veeam

Question 6

What happens to VM backups for a VM that has application-aware processing disabled in a Veeam backup job?

Accepted Answer

The VM receives only crash-consistent backups with no guest OS interaction or VSS quiescing

Answer

The VM is excluded from the backup job entirely and receives no protection

Answer

The VM uses hardware-level snapshots instead of Veeam's software-based VSS processing

Answer

Veeam automatically detects running applications and applies processing only when needed

Question 7

Which Veeam feature enables administrators to automatically verify that application-aware backups of Microsoft SQL Server are recoverable by performing isolated test restores?

Accepted Answer

SureBackup with an Application Group and SQL Server verification script

Answer

Veeam ONE's SQL monitoring dashboard with automated health checks

Answer

Instant VM Recovery with SQL Server validation mode enabled

Answer

Veeam DataLabs Staged Restore with SQL recovery mode selected
