About NetBackup appliance as a VMware backup

host

NetBackup appliance uses the VMware policy type to back up VMware virtual

machines.

The following topics contain notes on the appliance as the backup host:

■ For an overview of the appliance as backup host in a virtual environment:

See “NetBackup appliance as backup host: component overview” on page 14.

■ For a list of requirements and limitations:

See “Notes on NetBackup appliance as a VMware backup host” on page 15.

NetBackup appliance as backup host: component overview

As Figure 4-1 shows, the appliance can operate as the VMware backup host. A

separate Windows backup host is not required.

The appliance as backup host can also run the NetBackup media server and master

server.

NetBackup appliances support dynamic multi-pathing (DMP) in a SAN environment:

See “About appliance dynamic multi-pathing for VMware backups with SAN

transport” on page 15.

Further information is available on the appliance as backup host:

See “Notes on NetBackup appliance as a VMware backup host” on page 15.

Notes on NetBackup appliance as a VMware backup host

Note the following requirements and limitations for the appliance as the backup

host:

■ The appliance must be version 2.5 or later.

■ You must use the VMware policy type.

■

The appliance supports iSCSI connections. Refer to the NetBackup Appliance

iSCSI Guide for more information.

About appliance dynamic multi-pathing for

VMware backups with SAN transport

NetBackup appliances support dynamic multi-pathing (DMP) in a SAN environment

for VMware backups. DMP enhances I/O performance by distributing requests

across all available paths. DMP on the Appliance can distinguish between the active

paths and passive paths and make use of the active paths.

15VMware support

About appliance dynamic multi-pathing for VMware backups with SAN transport

In a failover scenario, inputs and outputs are rerouted to healthy data paths. The

failed paths are restored automatically when they become healthy. DMP also reduces

the complexity of managing thousands of I/O paths in case they need to be

temporarily disabled for array maintenance.

Supported Fibre Channel

features on NetBackup

appliances

This chapter includes the following topics:

■ About supported Fibre Channel features on NetBackup appliances

■ Fibre Channel feature support with appliance HBA configurations

■ Supported data transfer methods for NetBackup appliances

■ About Fibre Transport paths for NetBackup appliances

About supported Fibre Channel features on

NetBackup appliances

The appliances are rack-mount servers that run on the Linux operating system.

NetBackup Enterprise Server software is already installed and configured to work

with the operating system, the disk storage units, and the robotic tape device.

To use the NetBackup Enterprise Server software on the NetBackup appliance with

the supported Fibre Channel (FC) features, you must configure the appliance FC

settings first.

The NetBackup 52xx and 53xx appliances support the use of FC with some or all

of the following features depending on hardware configuration:

■ SAN Client

■ Optimized duplication

Chapter

■ Auto Image Replication

■ NetBackup for VMware

■ Tape out

Note: NetBackup appliance supports the use of the DD Boost plug-in and its

capabilities.

SAN Client

This feature provides high-speed backups and restores of NetBackup clients. A

SAN client is a special NetBackup client that can back up large amounts of data

rapidly over a SAN connection rather than a LAN. The backup and restore traffic

occurs over FC, and the NetBackup server and client administration traffic occurs

over the LAN.

You must enable the Fibre Transport media server (FTMS) feature on the NetBackup

52xx or 53xx appliance to use it for backing up SAN clients.

See “How to configure Fibre Transport media server for SAN Client” on page 71.

Optimized duplication

Note: Optimized duplication over FC is only supported with NetBackup appliance

products, and not supported with non-appliance NetBackup servers.

Optimized duplication copies the deduplicated backup images between appliances

within the same domain.

For optimized duplication over FC, the duplication source must be a NetBackup

52xx or 53xx appliance. The duplication destination can be a NetBackup 52xx or

53xx appliance.

The source and the destination must use the same NetBackup master server. The

optimized duplication operation is more efficient than normal duplication because

only the unique, deduplicated data segments are transferred. Optimized duplication

reduces the amount of data transmission over your network and is a good method

to copy your backup images off-site for disaster recovery.

You must configure appliances at both the source and the destination for optimized

duplication over FC.

See “How to configure Fibre Transport for optimized duplication and Auto Image

Replication over FC” on page 76.
