However, it is disabled inside virtual machines, so use HotAdd instead on a virtual VMware Backup Host.
SAN transport is usually the best choice for backups when running on a physical VMware Backup Host. For using SAN, make sure that datastore LUNs are accessible to the VMware Backup Host. In this mode, vStorage APIs obtain information from the vCenter server or ESX/ESXi host about the layout of VMFS LUNs and, using this information, reads data directly from the SAN or iSCSI LUN where the VMDK resides. This is an efficient data path because no data needs to be transferred through the production ESX/ESXi host. SAN: The SAN transport mode requires the VMware Backup Host to reside on a physical machine with access to Fibre Channel or iSCSI SAN containing the virtual disks to be accessed. If a combination of the transport modes is given, NetBackup and Backup Exec will try all of them one by one until gaining successful access to the data of the Virtual Machine. This article talks about these transport modes, the best practices around them and troubleshooting tips for some commonly seen errors related to transport modes in NetBackup and Backup Exec.įor both Backup and Restore operations, NetBackup and Backup Exec allow choosing any of the four transport modes or a combination of these. These methods are referred to as VMware Transport modes. 
A VMware Backup Host can access Virtual Machine data from datastores using four different methods – SAN, LAN(NBD), HotAdd, NBDSSL.
