Errors for backups of virtual machines on Virtual Volumes (VVols)

When troubleshooting backups of virtual machines on VVols, note the following:

  • Each NetBackup snapshot job creates a vSphere snapshot of the virtual machine.

  • To investigate snapshot failures, check the storage array's VASA provider logs as well as the vSphere error messages. (VASA is vSphere API for Storage Awareness.)

Table: Errors for backups of virtual machines on VVols

Error message or cause

Explanation and recommended action

vSphere snapshot creation fails for a backup of a VM on VVol.

Ensure that you have the required snapshot license from the array vendor. Licensing requirements for vSphere snapshots vary from one type of VVol storage to another, depending on the array vendor.

Each NetBackup snapshot job creates a vSphere snapshot of the virtual machine.

There is insufficient space in VVol storage.

Space requirements vary from one array vendor to another. Consult the storage array documentation.
