About the NetBackup PureDisk Deduplication Option
(PDDO)
The NetBackup PureDisk Deduplication Option (PDDO) is a plug-in that uses the NetBackup OpenStorage API to enable NetBackup to write backups to a PureDisk storage pool. All the data that is written to a PureDisk storage pool is deduplicated. In general, deduplication is a method of retaining only one unique instance of backup data on storage media. Redundant data is replaced with a pointer to the unique data copy.
Deduplication significantly reduces the amount of storage space for the NetBackup backup copies. All data that a PDDO agent or that a PureDisk backup client writes to a PureDisk storage pool are deduplicated. When two or more files share identical content, PureDisk breaks the files into segments and stores only one copy of each unique file segment.
The following figure shows how deduplication works.
1
Figure 1-1 File deduplication A B C D E A B Q D L Client files to be backed up A B C D E Q L Data written to content routers File 1 File 2
Note the following in this figure:
■ PureDisk breaks file 1 into segments A, B, C, D, and E.
■ PureDisk breaks file 2 into segments A, B, Q, D, and L.
■ PureDisk writes file segments A, B, C, D, and E from file 1, and file segments Q, and L from file 2 on its content routers only one time. PureDisk does not write file segments A, B, and D from file 2 to the content routers. Instead, PureDisk points to the unique data copies of file segments A, B, and D that were already written to the content routers from file 1.
Note:When using PDDO to deduplicate database backups (Oracle, MS SQL, and MS Exchange), snapshot-based backups deduplicate better than stream-based backups.
Before you install and implement the NetBackup PureDisk Deduplication Option, make sure that the following conditions are true:
■ The PureDisk storage pool software is configured and functions normally.
■ The NetBackup media server is configured and functions normally.
■ You are familiar with the concepts and procedures that are described in the
NetBackup AdvancedDisk Storage Solutions Guide, the Symantec NetBackup OpenStorage Solutions Guide for Disk, and your NetBackup administrator’s
guides.
After you install a PureDisk storage pool, you can download the PureDisk agent software to a computer.
Next you can configure it to assume one of the following roles:
■ A backup and restore agent. Overview
You can configure a backup and restore agent on any client that PureDisk supports. The Symantec Technical Support compatibility matrix explains the platforms upon which you can configure a PureDisk backup and restore client.
■ A PDDO plug-in.
You can configure a PDDO plug-in on a NetBackup media server. The NetBackup media server can be a Linux, Solaris SPARC, IBM AIX, or Windows platform computer. After you configure the plug-in, the media server can use the PureDisk storage pool as a NetBackup OpenStorage disk pool.
When you download the PureDisk agent software onto a NetBackup media server, the agent software detects the media server software. It issues the installation prompts that let you configure the agent as a PDDO plug-in. Make sure that you configure the media server software before you download the PureDisk agent software to the media server.
See“PDDO configuration examples”on page 13.
PDDO configuration examples
The following examples describe PureDisk and NetBackup configurations. The examples do not show any PureDisk backup and restore clients as being directly attached to PureDisk. However, PureDisk can act both as a storage unit to NetBackup and as a backup repository for its own PureDisk clients. When the storage pools fill up, you can add additional content routers to hold additional backup data from NetBackup and from the PureDisk clients.
■ Example 1: Deduplication
See“Example 1: Deduplication”on page 13.
■ Example 2: Multistreaming
See“Example 2: Multistreaming”on page 14.
■ Example 3: Replication
See“Example 3: Replication”on page 15.
Example 1: Deduplication
Two NetBackup environments with the PDDO plug-in each backup two clients. NetBackup then sends backup data to the PureDisk storage pool for deduplication. The PureDisk storage pool also deduplicates the data from its client.
The following figure shows how the PDDO plug-in works in this scenario to deduplicate data.

See“PDDO configuration examples”on page 13.
Example 2: Multistreaming
The NetBackup policy defines multiple data streams from the client to the NetBackup media server. NetBackup sends data to the PureDisk storage pool in multiple streams.
The following figure shows how NetBackup multistreaming works in an environment that includes both NetBackup and PureDisk.

See“PDDO configuration examples”on page 13.
Example 3: Replication
PureDisk’s replication feature is similar to NetBackup’s optimized duplication feature. Replication gives you more options if you need to restore data because you can restore from either storage pool.
You can replicate the data from a given PureDisk storage pool to another PureDisk storage pool with one of the following features:
■ PureDisk replication
■ NetBackup optimized duplication
Both features transfer only the changed data segments directly between the PureDisk storage pools. NetBackup media servers can restore data from either storage pool. When you replicate data between storage pools, you create a very efficient data transfer environment for disaster recovery scenarios.
NetBackup does not keep track of PureDisk replicated images. Images can be imported into NetBackup.
If you use optimized deduplication, the media server must be registered with both storage pools.
The following figure shows how you can use PureDisk’s replication feature with PDDO when you have two PureDisk storage pools.

About improvements to the synthetic backup process
Starting with PureDisk 6.6 and NetBackup 6.5.4, the process for creating synthetic backups is improved. The new process for creating optimized synthetic full backups is through the manipulation of NetBackup catalog metadata and PDDO data Overviewsegment pointers. Only the metadata and pointers are manipulated. In the new optimized synthetic backup process, the backup image data is not read from disk, transported across the network, or manipulated.
Using the new optimized synthetic full backup process allows the creation of full backups with a significant performance improvement. The optimized synthetic backup is then stored on a PDDO storage unit as an ordered collection of data segments representing a new full backup. The benefit of the optimized synthetic full backup is the ability to run a single full backup, and then only incremental backups from that point forward. Ongoing NetBackup incremental backups of only new or modified data allows users to quickly create a new full backup, at any point in time, by performing an optimized synthetic full backup.

Downloading the PDDO
plug-in
This chapter includes the following topics:
■ About downloading the PDDO plug-in
■ Verifying your environment
■ Verifying or installing the PDDO license on a NetBackup master server
■ Downloading the PDDO plug-in to a media server
About downloading the PDDO plug-in
The PDDO plug-in software is available as a link from the storage pool authority landing page. The download process includes system verification steps and the actual download steps themselves.
To download the PDDO plug-in
1
Verify your environment.See“Verifying your environment”on page 20.
2
Verify or install the PDDO license on a NetBackup master server.See“Verifying or installing the PDDO license on a NetBackup master server” on page 21.
3
Download the plug-in to a media server.See“Downloading the PDDO plug-in to a media server”on page 22.
2
Verifying your environment
Before you download or install the PDDO plug-in, perform the following procedure. To verify your environment
1
Verify that NetBackup 6.5 or later is installed and configured on the media server that you want to use.To verify your release level, perform the following steps:
■ Logon to the NetBackup Administration Console.
■ Click Help.
■ Click About NetBackup Administration Console.
■ Visually inspect the number to the right of Version.
Make sure that you can perform backups and restores with NetBackup. For information about how to configure NetBackup, see your NetBackup installation documentation.
2
Verify that the NetBackup media server upon which you want to install the PDDO client is a good candidate for this purpose.The hardware must be suited for both I/O and for computation. PDDO increases the computational load on a media server because it calculates data deduplication. Verify your media server’s hardware capabilities to ensure an optimal PDDO configuration.
3
Verify that the PureDisk storage pool is configured and operational. The NetBackup interface refers to the PureDisk storage pool as a "storageserver."
Make sure that you can perform regular file backups from a client and restores to a client. Install a regular PureDisk backup and restore agent on a client computer to perform this test. Do not install the regular backup and restore client on the media server. Symantec does not support both a backup and restore client and a PDDO plug-in on one NetBackup media server. Information about how to install a PureDisk backup and restore client is available.
See the PureDisk Client Installation Guide.

media server or a UNIX NetBackup media server and
the PureDisk storage pool
This topic explains how to configure the PDDO plug-in on the media server, point the media server to a PureDisk storage pool, and create the PureDisk storage server.
After you perform this procedure, the software initiates the following activities:
■ Activates the PDDO plug-in as a client to the storage pool
■ Registers the media server as a client to the storage pool
■ Creates a PureDisk PDDO data selection
Note:Do not delete the PDDO data selection. If you delete and then want to recreate this data selection, you need to reinstall the PDDO plug-in. You cannot recreate this data selection from the PureDisk administrative Web UI.
To establish the PDDO connection between a UNIX NetBackup media server and the PureDisk storage pool
1
Change to the PDDO plug-in’sbindirectory. For example:# cd /install_directory/pdag/bin
For install_directory, specify the directory in which you installed the PDDO plug-in. The default is/opt.
2
Type the following command to make NetBackup aware of the PureDisk storage pool and aware of the PDDO plug-in on the media server: # sh ./pddocfg.sh --addspa --mediaserver=ms_addr --storageserver=spa_addrThe arguments to this command are as follows:
Specifies the media server’s FQDN, host name, or IP address. Symantec recommends that you type the full FQDN of the media server. For example, acctms.acme.com.
ms_addr
Specifies the PureDisk storage pool authority’s FQDN (recommended), host name, or IP address. The storage pool authority identifies itself with this address. You also enter this address in a browser window to logon to the storage pool authority.

Complete the fields on the Storage Unit Creation - Enter details to createStorage Unit page, and then click Next.
Define the following parameters for the storage unit:
■ In the Storage unit name field, specify the storage unit name. For example, you can useacme.com-STU1. After configuration, this name appears in NetBackup’s list of storage units in the NetBackup interface.
■ In the Media Server pane, select Use any available media server in the
disk pool or Use only the following media servers.
Use the following information to make your selection:
■ If you have only one media server, it does not matter which option you choose.
■ If you have multiple media servers and you select Use any available
media server to transport data, NetBackup chooses from among the
available media servers for backups. Choose this option if you plan to add other media servers to this PureDisk storage pool in the future. You do not need to update the storage units at that time.
■ If you have multiple media servers and you select Use only the selected
media servers, NetBackup uses the specified media server(s) when it
runs.
■ Set the Maximum concurrent jobs to 40.
■ Confirm the Maximum fragment size is set to 51200. The unit of measure is megabytes for this field, so this value equals 51,200 megabytes (or 50 gigabytes).
In the NetBackup Administration Console, select NetBackup
Management > Storage > Storage Units, and the New Storage Units
display appears. On this display, confirm the Maximum fragment size field to 51200. Symantec recommends you do not modify this value. If the Maximum fragment size is set to a value greater than 51200, backups that attempts to write fragments greater than 51200 megabytes fail with an “image size exceeded” error. If you specify a smaller value, you incur more maintenance because there are more fragments, but there is less overhead per fragment.
More information about these settings is available.

Type a name for this policy.4
Create the NetBackup backup policy manually.NOTE: Do not use the Backup Policy Configuration Wizard. You must create the policy manually.
When you create this policy, make sure to specify the following options:
■ Disable compression
■ Disable encryption
If compression and encryption are enabled in NetBackup, the data is modified before it reaches PureDisk, and PureDisk cannot deduplicate it correctly. PureDisk compresses and encrypts the data once it is deduplicated. The next step explains how to enable compression and encryption.
5
Edit thepd.conffile to enable compression and encryption, if required. Symantec recommends enabling compression to help conserve disk space your PureDisk environment. Perform this step if you need compression and encryption when NetBackup writes the backup images to the PureDisk disk pool.PureDisk’s deduplication feature relies on the ability to detect similar patterns in files from one backup to the next. When you enable NetBackup encryption and compression, PureDisk cannot detect patterns in file content and deduplication effectiveness decreases.
Thepd.conffile is a configuration file on the media server. More information about how to specify settings in this file is available.
See“About the pd.conf file”on page 91.
6
(Optional) Configure NetBackup for multistreaming.To run more than one job per NetBackup client, make sure to configure NetBackup to run more than one stream. For information about multistreaming, see your NetBackup documentation.
7
Run a manual backup and restore the files from the backup.If you can perform this backup and restore, then the configuration works properly. For information about NetBackup backups and restores, see your NetBackup documentation.
