1 Introduction Symantec® NetBackup™ is an Enterprise class data protection application. Its architecture is designed for a large and complex distributed computing environment. NetBackup provides scalable storage servers that can be configured for a variety of tasks such as backup, recovery, archiving and file migration. NetBackup provides a variety of client agents for different operating systems and applications and a variety of additional functions such as Advanced Disk and the implementation of the Symantec Open Storage API( OST). Symantec NetBackup also has the capability of client side and central server software-based deduplication based on the PureDisk™ technology. NetBackup media servers can use disk or tape for storage targets. NOTE: It is not the intention of this guide to cover all features of the Symantec NetBackup product. For example: this guide will not cover the Symantec NetBackup deduplication options using PureDisk™ technology because this is a software deduplication option which would not be compatible with a deduplication appliance based solution such as the D2D Backup System. The objective of this guide is to provide: 1. Step by step instructions on how to configure the D2D NAS share to be used as a disk storage target by a NetBackup media server. The example uses the CIFS protocol. The CIFS protocol is used with media servers running on a Microsoft Windows platform to access network-based disk. To use with UNIX systems the NFS protocol must be used. 2. A guide to highlight some of the optional settings when configuring NetBackup. 3.

1 Introduction
Symantec® NetBackup™ is an Enterprise class data protection application. Its architecture is
designed for a large and complex distributed computing environment. NetBackup provides scalable
storage servers that can be configured for a variety of tasks such as backup, recovery, archiving
and file migration.
NetBackup provides a variety of client agents for different operating systems and applications and
a variety of additional functions such as Advanced Disk and the implementation of the Symantec
Open Storage API( OST). Symantec NetBackup also has the capability of client side and central
server software-based deduplication based on the PureDisk™ technology. NetBackup media servers
can use disk or tape for storage targets.
NOTE:
It is not the intention of this guide to cover all features of the Symantec NetBackup product.
For example: this guide will not cover the Symantec NetBackup deduplication options using
PureDisk™ technology because this is a software deduplication option which would not be
compatible with a deduplication appliance based solution such as the D2D Backup System.
The objective of this guide is to provide:
1.
Step by step instructions on how to configure the D2D NAS share to be used as a disk storage
target by a NetBackup media server. The example uses the CIFS protocol.
The CIFS protocol is used with media servers running on a Microsoft Windows platform to
access network-based disk. To use with UNIX systems the NFS protocol must be used.
2.
A guide to highlight some of the optional settings when configuring NetBackup.
3.
Worked examples showing how to back up to a D2D NAS target and replicate to another
D2D systems.
4.
An explanation of some of the more complex NetBackup concepts.
5.
A worked example showing how to recover data from the replication D2D target system.
As the guide will show, selection of the protocol and network configuration is quite easy using the
D2D Web Management Interface (GUI). Symantec NetBackup is a highly scalable product and
could easily support multiple D2D systems.
The NetBackup environment
The
NetBackup Master server
manages backups, archives and restores. It is responsible for all
media (can be tape or disk) selection and maintains an internal database called the catalog. The
catalog tracks backup and media and is used to quickly locate the correct media and backup
items.
The
NetBackup Media server
distributes the load in large configurations. Storage devices are
attached to media servers via SCSI, SAN or network connection. It is possible for a media server
to be present on the same physical server as the master server. (A two-tier configuration is often
used in smaller configurations.) In this case the media server is on the same server as the master
server. A master server can control many media servers. It is possible in large enterprise scale
operations to have multiple master servers. Often media servers are referred to in the following
terms:
•
Storage Server
– when disks are connected directly to the media server I/O. In this configuration
disks can be configured in an OpenStorage disk pool.
•
Device Hosts
– when physical or virtual tape libraries are attached.
