When processing a backup, replication, or recovery job the following message is displayed:

No Format
Backup / Replication / Recovery / Flash boot / Screenshot verification of the VM_NAME VM cannot be started
SAN transport mode cannot be used by the Transporter to access one or more disks of this VM.


This error occurs if you are using VVol or vSAN datastores. The reason is a known issue in the VDDK library, which is used for managing and accessing VMware virtual disks. The issue


will be fixed in one of the


upcoming releases.


The temporary workarounds are:

  • explicitly Explicitly specify another mode, such as NBDSSL or HotAdd
  • move Move the virtual disk to a VMFS datastore.
