Answer-

There are two types of RDM disks. RDM disks can be placed into Physical or Virtual

compatibility Mode. Physical compatibility mode (i.e. persistent-independent) bypasses the

ESX storage infrastructure (vmfs file system) and thus cannot have a snapshot taken by

VCB. Physical compatibility mode RDM disks in this configuration are skipped

automatically during the backup. Virtual compatibility mode RDM disks are not skipped

and are included in the backup automatically and will include ALL data located on the

mapped LUN.

For Physical compatibility mode RDM disks, Backup Exec Remote Agents can be installed in

the Guest virtual machine to backup their data using traditional backup methods.

8. How should my VCB “Proxy Server” be configured?

Answer-

A VCB Proxy Server’s purpose is to temporarily store the VCB snapshots created during the

backup of the Guest virtual machines so that it is the temporary snapshots can then be

backed up by a 3

party backup application. VCB Proxy Servers can be created on any

Windows 2003 server that has connectivity to the VMware infrastructure by installing the

VCB framework software from VMware on them. There can even be multiple VCB Proxy

servers in larger VMware environments. In general, the following recommendations apply:

• For performance reasons, it is recommended that the Backup Exec server and the

VCB Proxy Server be installed on the same system so that the VCB snapshots being

backed up are done locally instead of across the network.

• The VCB Proxy Server disk sub-system should be built around multiple-spindle,

low-cost, fast disks. All disk subsystem types supported by Windows are supported

for use on the VCB Proxy Server.

• Multiple physical disks in a RAID 0 configuration would be recommended.

Reliability, such as RAID 5 systems, should not be a primary concern since the VCB

Proxy Server will only contain temporary snapshot copies of production data.

• For specific VCB Proxy Server sizing recommendations please see the Backup

section of this document below.

9. Can Backup Exec 12.5 Media Servers be installed on a Guest virtual machine

running on an ESX server?

Answer-

Yes, Backup Exec 12.5 media servers can be installed in a supported guest virtual machine

OS running on an ESX server to protect the entire server. However, the benefits of

performing an “off-host” snapshot backup away from the ESX server will not be realized if

the Backup Exec server is virtualized and backup I/O is impacting the performance of the

ESX server. In this configuration it is recommended that the ”Hot Add” backup transport

method be selected in the Backup Job Properties|VMware Virtual Infrastructure settings

screen in Backup Exec 12.5.

It should also be noted that VMware ESX support of local tape devices is limited to only

certain SCSI hardware configurations. The directions for connecting the SCSI backup
