Why Does Instant VM Recovery Get Stuck Dismounting?

The instant VM recovery with status "dismounting" occurs after the VM has been restored and is ready to switch from running on backup storage to production storage.

During this phase, Veeam releases the backup repository, transfers data back to the production environment, and shuts down the temporary VM. However, if something goes wrong, this process can become stuck, preventing the VM from being fully restored.

This article focuses on the issue of Veeam instant VM recovery stuck dismounting, analyzing the potential reasons and offering solution.

  • Network latency: If your network is slow or experiencing high latency, the dismounting process may stall.
  • Backup job failures: Other ongoing backup or replication jobs might interfere with the dismounting process.
  • Hypervisor-related problems: The underlying hypervisor is not running (VMware or Hyper-V) or might be causing delays due to resource allocation or configuration issues.
  • Locked or active files: Sometimes, files on the host machine remain locked or active, preventing the dismount process from completing.
  • Database issues: Problems with the Veeam configuration database or loss of connection to the backup infrastructure can cause jobs to hang.
