Transportation mode
Select the transportation mode to be used for backing up the virtual machine.
The following modes are available:
LAN: Use this mode when your ESX(i) Server systems do not have access to a
SAN, but use local storage devices or NAS to store virtual machine disks. This
is an unencrypted transportation mode over a local area network that uses the
Network Block Device (NBD) driver protocol. This transportation mode is
usually slower than Fibre Channel.
LAN (SSL): Same as LAN except that the communication over the network is
encrypted using the Secure Socket Layer (SSL) cryptographic protocol.
Hotadd: Use this mode if your backup host (a client with the Data Protector
Virtual Environment Integration component installed) is a virtual machine. This
mode enables you to back up virtual machines that reside on datastores visible
to the ESX(i) Server system which hosts the backup host. The Hotadd
transportation mode requires that the datastores are presented to the backup
host in the same manner as they are presented to a physical system.
SAN: Use this mode when your ESX(i) Server systems store their virtual
machine disks on Fibre Channel SAN or iSCSI SAN and the backup host is a
physical machine. This is an unencrypted transportation mode over Fibre
Channel or iSCSI. For details, see the “VMware SAN configuration guide”.
This transportation mode requires that the storage volumes on which the virtual
machines reside are presented to the backup host.
Caution: Do not reformat these storage volumes. Otherwise, you will delete all
your virtual machines.
If you are not concerned which mode is used, select Fastest available.
For details on how to configure a VMware environment for different
transportation modes, see the “Virtual Disk API Programming Guide” at:

Default: Fastest available
Note
With VCB 1.5 (08/01/2008 | Build 102898), VMware introduced Hotadd transportation mode.
