Reduce Complexity

Deduplication, Store Data More Efficient

3

• Places to deduplicate:– Source

– Target– At the media server

– With appliances

• Benefits include:– Backup Less data = faster

– Dramatically reduced storage costs and backup load

Deduplication Eliminates Redundant Data

• Target Deduplication– Can be a non-disruptive way to add dedupe

to your environment

– Expensive dedicated appliances ingest data at the end of the backup process

– Doesn’t do anything to help your backup infrastructure scale

Target-Side vs Source-Side Deduplication

Target Deduplication Appliance

• Source Deduplication– Reduces the amount of data sent over the

network, freeing up bandwidth– Reduces data through backup infrastructure– Suitable when application/client server can

handle the dedupe processing load Backup Disk Pool

Deduplication at the Source

• Data is deduplicated at the source/client before being sent across the network

• Benefits include:– Built-In to NetBackup, simple and easy to

deploy

– Reduced WAN/LAN bandwidth impact

– Reduced backend storage requirements

– Transparent support for applications

• Ideal for:– Remote offices

– Protecting virtual machines

– File/folder & Database backups with low change rate

Media Server Deduplication

• Data is deduplicated inline at the media server before being stored on disk

• Benefits include:– Built-In to NetBackup, simple and

easy to deploy

– No client impact

– Leverage commodity hardware

– Reduced backend storage requirements (1Gb/s vs. 10Gb/s)

– Highly scalable

• Ideal for: – Data center environments

= Deduplication engine

Deduplication platform

Deduplication Architecture

• Deduplication storage embedded into the NetBackup Media Server

• Deduplication plug-in embedded in standard NBU client

• Data moves directly between client and Deduplication Store (Media Server Deduplication Pool)

• Master/ Media servers required for Control Communication, Catalogue meta data repository and Policy management

• Transparent client deduplication support for applications (VMware, SQL ,...)

• Support for existing PureDisk pool

Load balancing option

• Deduplication load sharing Additional Media servers can be enabled to contribute to the deduplication process, all writing to the same Media server deduplication pool

• A simple check in the box to enable deduplication

• Global deduplication is maintained within each deduplication pool

• Support for PureDisk Deduplication Pool

Media Server Deduplication Performance Example

• Performance depends on a lot of factors– network, deduplication rate, disk

write speed, CPU power …

• Example for 10Gb/s network and multiple backup jobs– 16 jobs deliver a total of 900MB/s

– or 3TB/hour

• Add more media servers

to achieve higher throughput

Integration with Deduplication Appliances• Data is deduplicated at the

appliance, yet centrally managed by NetBackup via OpenStorage API

• Benefits include:– It allows NetBackup to see the disk, as

disk, giving NetBackup visibility and control of advanced features

– Centralized policy management and replication control

– Improved performance

• Supported appliances include:
