device to a virtual machine through the SCSI pass-through mechanism are detailed in the

ESX Server Administration Guide and include the following restrictions:

• VMware supports attaching SCSI drives to the ESX Server using Adaptec SCSI

adapters. Using other adapters, such as LSI MPT‐Fusion SCSI, is not supported.

• If using a tape drive library (versus using a stand‐alone tape drive), the library

must be multi‐target, and not multi‐LUN.

• Set the tape drive’s virtual target ID in the virtual machines configuration to be the

same as the physical target ID.

• Fibre Channel attached tape devices are not supported by VMware

• Ensure the tape device is a supported device on the Backup Exec Hardware

Compatibility List at

http://seer.support.veritas.com/docs/306831.htm

For these reasons, it is recommended that backup-to-disk (B2D) devices be used for

backup targets for Backup Exec 12.5 servers running inside of guest virtual machines on

ESX.

Backup

1. What methods of backup are currently supported with Backup Exec 12.5’s AVVI?

Answer-

VMware VCB provides several different backup methods that AVVI can take advantage of

depending on your storage and networking configuration. Backup Exec 12.5 AVVI supports

all of these current methods including:

• FibreChannel SAN-based “off-host” snapshot backups

• iSCSI SAN-based “off-host” snapshot backups

• NBD/NBDSSL network-based snapshot backups

• Local backups via ESX 3.5 “hot-add” snapshot backups

Off-host backups avoid performance impacts on the ESX server during backup.

2. How are Guest virtual machines protected?

Answer-

AVVI provides Full backups of Guest virtual machines through VMware’s VCB backup

framework. All backups are performed at a complete image-level of the Guest virtual

machine and can be done using the backup methods described above to a Windows “VCB

Proxy” server. All necessary files of the Guest virtual machine are automatically protected

via VCB including:

• .vmdk files

• .vmx files

• .log files

• .nvram files

3. Can I perform Incremental or Differential backups of Guest virtual machines?
