After recently upgrading to 5.4.0 or newer you notice that the backup jobs are now failing trying to perform Lan-Free backups (VDDK SAN or HotAdd). Pre the upgrade the backup jobs did not have perform Lan-Free selected. The backups are completing after failing back to network.
Starting with vRanger 5.4.0 the virtual appliance can now be used to perform a backup and vRanger is now able to automatically select the backup transport based on what type of machine vRanger is installed on and if a virtual appliance is being used. With the upgrade the transport failover is set to automatically and attempts Lan-free transport first before performing a network based transport.
To correct this, you will need to edit each backup job under the Transport Selection make the changes below.
