2. Symantec’s Prescription For Better Data Protection
Deduplicate Everywhere To Rationalize Infrastructure
Archive for Long Term Storage & Improve Backup Performance
Centralize Management To Reduce Complexity
So what is Symantec’s prescription for better data protection? It’s really around three key areas.
Deduplicate everywhere to rationalize infrastructure – what does that mean? Well deduplication is all about eliminating redundant data. Backup is essentially a copy of a customer’s data and as a result – customers can end up backing up and storing a lot of duplicate data. With deduplication technology – it ensures that only the unique data, the changes, are backed up. This can provide tremendous value to customers in reduced bandwidth and storage.
Archive for long term storage and improve backup performance. If customer’s like the concept of deduplication technology, they’ll love archiving. Archiving takes less used data off of primary storage and moves it into the archive. This provides many benefits – 1) as data is moved into the archive it enables quick and efficient search and e-discovery which helps address government regulation requirements, particularly those around . And 2) it helps improve backup and recovery. And the benefit to backup is essentially a “trickle down” effect. Less data means faster backups and faster recovery, less storage required and reduced bandwidth impact.
Centralize management to reduce complexity. Today’s IT admins are challenged with monumental data growth (IDC says 50-60% CAGR), yet budget continues to be reduced and jobs cut. That means many organizations are forced with having to do more with less. And if the data is heterogeneous and distributed, which it typically is in an enterprise data center, managing this complexity can cause data to be lost and SLA’s to be missed.

3. Deduplication, Store Data More Efficient

Symantec advocates that customers deduplicate data everywhere, as close to the source as possible. Traditional appliance based deduplication occurs at the end of the backup data path, but this leaves significant savings on the table. By moving deduplication closer to the source, customers can reap more benefits from backup times, to network usage, to backup infrastructure.
#1 We believe that most customers could use client side deduplication for as much as 50-70% of their data. The result will be faster backups, up to 99% less network usage, and of course, less storage consumption. NetBackup 7 deduplication is fully integrated and supports all clients, applications, and databases.
Client Side Value: Faster Backups, up to 99% less network, fully integrated, and full application & database support
#2 Of course, not all data is equal, and sometimes a particular client may not be suited to client-based deduplication. Or maybe a customer is not ready to upgrade their clients as part of a NetBackup 7 upgrade. For these instances, media server integration can be used. Regardless of whether client or media server is used, the data goes to the same disk target.
A given media server can manage up to 32TB of deduplication data. A dedupe disk target can be configured with a simple wizard and commodity disk. Because we include replication and license based on a front-end / source data, it’s very easy and cost effective for a customer to begin replicating backup data to another location. We’ll talk about this more in the Better DR section of our presentation. The value of using commodity storage behind NetBackup for deduplication, especially when configured for replication, makes it easier to deploy deduplication everywhere. The savings can be up to 70% when compared to a replication approach with appliances.
And going back to the usability theme, we mentioned earlier, we made it easy for organization to see their deduplication rates at a glance in the administration console.
Backup Server: No Client Impact, Scales Efficiently, Easy Configuration, Up to 70% Less Than Appliances*
#3 Of course, some customers may choose an appliance based approach for deduplication, despite the benefits of source-based deduplication, or may already have a dedupe appliance. NetBackup OpenStorage can turbo-charge these appliances giving customers more control and performance. The leading dedupe appliance vendors today, EMC/Data Domain, Quantum, and FalconStor all participate in OpenStorage and offer plug-ins for NetBackup today.
Of course, the beauty about NetBackup 7 and OpenStorage is that a customer does not have to choose one or the other. A customer can have an appliance and still use NetBackup 7 client/source-based deduplication. True, the data will exist in separate “pools”, but the management of each copy of data at each location will be centralized by NetBackup. Organization can not only manage the policies centrally, but monitor and report on data on a global basis.
Storage Appliance / OpenStorage: Simplify Management, Improve Infrastructure, Better Performance
Symantec also kept in mind existing customers using PureDisk. NetBackup 7 is compatible with existing PureDisk storage pools which means that an existing customer can upgrade to NetBackup 7 and use the new client deduplication to backup to their existing PureDisk storage pool. Or they can use media-server deduplication to backup to a PureDisk storage pool.

Support for existing PureDisk pool
NetBackup Media server
NetBackup deduplicaton plug-in controls the data path to and from the disk storage device. As such, the traditional nature of the NetBackup Media server becomes redundant as a data mover.
This feature seeks to improve upon NetBackup backup and restore performance by installing the PureDisk plugin on the client, and transmitting the data directly from the client to the disk storage device without routing through the NetBackup Media Server.
The Master Server and Media Server are still required, as the command and control aspects of the policy execution will remain unchanged. Small amounts of control communication will still be flowing from the Media Server and Master Server in the configuration.
The PureDisk Proxy Plugin
Located on the NetBackup Media Server – this component replaces the locally installed PureDisk/OST storage server plugins (i.e. AdvancedDisk, SharedDisk, PureDisk, etc) and reroutes (or proxies) all data movement operations from the media server to the to the Proxy Server running on the client machine.
The OST Proxy Server
Located on the client machine – this NetBackup Corba service implements the entire Version 10 specification of OST API as network RPC mechanism. The NBU media server interfaces with the ProxyServer via the proxy plug-in. The ProxyServer receives the OST remote procedure calls and then routes them to the OST copy manager plug-in. For example, when the bptm process running on the media server calls the sts_copy_image() function via the proxy plug-in – that function call is remotely executed by the ProxyServer.
The OST CopyManager Plugin
Located on the client machine – this component loaded by the ProxyServer – it receives performs the OST API function that was called originally on the NBU media server. It is responsible for performing the actual data movement operations on the NBU client. The Copy Manager Plug-in is itself implemented using the OST API. This is termed a “layered” OST implementation. As such, the CopyManager plug-in invokes the OST Shared Memory plugin to read from shared memory duing a backup, and write to shared memory duing a restore. The CopyManager also invokes the OST storage server plugin to write or read to the disk storage device.. For example, during a backup operation the Copy Manager plug-in will read from shared memory and write to the storage device via it’s plugin. To support this model all NetBackup client components (bpbkar, tar, bkar32, XBSA, etc) will be directed to use their share memory interfaces during backup and restore operations.
OST Shared Memory plug-in
Located on the client machine – this component interfaces with the NBU components via shared memory.
It supports shared memory backup and restore operations to the following NBU client components:
Bpbkar, tar, Windows TFI, DataBase Agents (XBSA).
OST Storage Server plug-in
Located on the client machine – this component interfaces directly with the storage device.
Restore path always happens through a Media Server (PDDO, MSDP or client dedupe) with NBU 7, NBU plan to have restore data directly to the NBU client, avoiding the NBU path.

Support for PureDisk Deduplication Pool
NetBackup Clients
Delivers load balancing and scalable performance architecture – Since NetBackup 6.5, the user has the flexibility to enable multiple media servers with the deduplication option, all sharing the same external PureDisk pool. This feature allows a user to increase backup throughputs and leverage the built-in media server load balancing by simply enabling extra media servers. The more media servers are enabled with this option, the more processing power there is available for the deduplication process and the higher the aggregated backup performance will be. The engineering team has now extended this exciting feature in NetBackup 7.0 for media server deduplication pools, allowing multiple media servers to share the same media server deduplication pool.
The following figures show how automatic load balancing can be accomplished for media server deduplication pools and still support external PureDisk pools. Global deduplication is maintained within each individual pool, no matter how many media servers or clients are storing data to that pool. There is no deduplication across multiple pools, expect when optimized duplications are performed between pools
Simplified configuration – In NetBackup 7.0 a new “Configure disk storage servers” wizard guides the user in configuring the connection to an external PureDisk pool. Gone are the days where command line scripts were run to exchange the necessary credentials between the two components. Even better, once configured and credentials are exchanged, NetBackup stores the information in its database so it can be reused by any other media server in the same NetBackup domain. In the past one had to run a script on each one of the media servers to enable access for that media server. Today this is replaced by a simple ticket in the box in NetBackup’s administration interface.

Archive data off primary storage & dedupe data
Symantec advocates that customers deduplicate data everywhere, as close to the source as possible. Deduplication includes not just the reduction of duplicate backup data, but the reduction of old data off primary servers – archiving. Moving old data into an archive with Enterprise Vault, that also eliminates deduplicate data, benefits the backup and recovery process.
With backup deduplication, the traditional approach has been to use appliances, which perform deduplication occurs at the end of the backup data path. This leaves significant savings on the table. By moving deduplication closer to the source, customers can reap more benefits from backup times, to network usage, to backup infrastructure.

16. Better DR with Global Data Protection

17. Better Disaster Recovery for Global Data Protection
One Console To View Distributed Backup Information
Replicate & Store 80% Less Data Duplication
Recover terabytes of data in seconds from anywhere
Better Disaster Recovery with NetBackup 7. Traditional disaster recovery for many large organizations is largely divided into two camps - critical application recovery made possible with high availability replication - and the rest of corporate data – slower to recover and largely on tape. The former, offers instant recovery at a high price, and the later, slow recovery at a much lower price. With more key business applications to bring online at a DR site, organizations need alternatives that don’t add complexity to their data center.
NetBackup 7 meets this need by allowing customer to recover information more quickly using less infrastructure and tools. It integrates deduplication, continuous data protection, and replication into one platform.
1) Better disaster recovery can’t occur when backups silently fail. The new OpsCenter console in NetBackup provides monitoring, alerting, and reporting for Symantec backup and archive products, as well as 3rd party products. It helps teams make sure data gets to an alternate site.
2) Recovery from disk can be faster at a DR site versus tape, especially if it tape need to be recalled before it can be used. NetBackup reduces the amount of data that must be stored and moved by up to 80% with integrated deduplication; automatically replicates it to an alternate site; and then expires it when needed making space available for more backups.
3) But transforming disaster recovery is about more than backup replication. NetBackup can dramatically change the nature of application recovery by leveraging continuous data protection and live replication. It can make data available in seconds from anywhere, eliminating the time and infrastructure needed to recover from backup systems to production ones.
NetBackup 7 transforms backup and disaster recovery by providing a single view of global backup data and enabling both efficient replication and fast recovery of data, wherever it exists.

18. Move Up to 80% Less Data With Optimized Duplication
One Policy for Backup & DR Copies
Site 1
Site 2
Symantec believes that optimized duplication, powered by deduplication and replication, can change the way customers use their data center infrastructures. Optimized duplication, is the act of using deduplication to create a 2nd copy of data at an alternate location, thereby eliminating the create and ship tapes for DR purposes. Symantec customers have seen deduplication reduce the amount of data that must be moved to an alternate site by as much as 80-90%. With this level of data reduction, transmission over a WAN becomes not only viable, but cost-effective. Duplicate copies of backup data, as opposed to replication, not only provide customers with DR capabilities, but allow them to set different retention times.
The storage lifecycle policy feature within NetBackup helps organizations more easily manage this process. We show a screenshot of such a policy on this page to demonstrate the simplicity of a configuration. Organization can define one lifecycle policy and apply it to a large number of backup policies which simplifies administration for DR purposes. Without deduplication, replication of backup data would take time and require massive amounts of bandwidth. With NetBackup deduplication, organizations can transmit only the changed blocks in a process called optimized deduplication.
The diagram below illustrates how NetBackup can initiate an optimized duplication job using native deduplication or a storage appliance that uses OpenStorage (OST). If you look at site 1, you’ll see that they maintain data online for 14 days. After that point, they may expire the data in that location to maximize disk use, but still maintain a copy online at the DR site. And from the 2nd site, an organization could write the data to tape to meet regulatory or other retention requirements.
