Vmbackvcbtransport

Use the vmbackvcbtransport option with the backup VM command to specify the transport mode to be used with VMware Consolidated Backup (VCB).

The vmbackvcbtransport option determines how VCB accesses virtual disk data.

Important:

Full VM backup uses the VMware VCB support. Use the vmbackvcbtransport option to control the transport mode for full VM backups.
File-level backup uses the vStorage for Data Protection APIs, and determines the best available transport. The vmbackvcbtransport option is not necessary for file-level backups.

Supported Clients

This option is valid only on supported Windows clients that are installed on a vStorage backup server. The server can also define this option.

Options File

Place this option in the client options file, or on the command line.

Syntax


                       .-RETRY--.   
>>-VMBACKVCBTransport--+-SAN----+------------------------------><
                       +-LAN----+   
                       '-HOTadd-'

Parameters

RETRY: Attempt access using the SAN to the virtual machine data from the backup proxy. If the SAN access is not available, try the operation again using the LAN transport. RETRY is the default.
SAN: Use the SAN to access virtual machine data from backup proxy.
LAN: Use the LAN to access virtual machine data from the backup proxy. LAN access is the same as the Network Block Device (NBD) protocol, which can be set on the VCB vcbmounter command.
HOTadd: Use the VMWare hotadd transport to access virtual machine data from the backup proxy. For information about the VMWare hotadd transport method, see the VMWare product documentation at http://www.vmware.com.
Note: The additional setup that is required to use hotadd transport that is documented in VMware documentation is not required for file-level backups.
