Traditional Storage Approaches



Most Common Storage Architecture Practices

15% Disk to Tape to Tape

15% Disk to Disk to WAN

15% Disk to Disk – no offsite

10% Disk to Tape – no offsite

31% Disk to Disk to Tape


But I thought tape was dead?


Tape adoption continues to decline, but curve is shallow

• Preservation of existing investment

• Continued cost advantage: per GB, KW, BTU

• Existing niche: Long term archiving

• Competing investment priorities (hardware, software, tools,etc)

• Less IT staff, less specialization

• Challenge to accommodate volume of information along with retention requirements

• Backup and recovery planning spread across vendors, fueled by shifting data needs

Disparity adds complexity and cost…

Today’s IT Challenges: Why Better Backup Is Needed?

• Can’t “see” across virtual and physical machines

• Incompatible storage tiers

• Multiple management consoles

• Multiple vendors/maintenance/support


“Organizations small and large need a holistic protection strategy, a single platform or solution, to handle the variety of data types and workloads as opposed to integrating a number of disparate point solutions…”

Dave Russell VP, Storage Technologies and Strategies, Gartner

Disparate Solutions

KEY DRIVERS FOR IT ORGANIZATIONS

• Cloud

• Snapshots

• Deduplication

• Appliances

DISRUPTIVE TECHNOLOGY TRENDS

1. Minimizing cost & complexity

2. Ability to meet backup windows

3. Data growth rates average 30%+


Cloud



What are they doing? Who is using it?

Cloud as Storage


Remote (offsite) data storage

Cost savings over existing process

Predictable costs vs internal methods

Remote Office / Branch Office

Improved SLAs

Eliminate on-site complexity

Takes advantage of new technology

Better management / reporting

Offload compliance to provider

Facilitates chargeback to business units

?

Why aren’t IT Organizations moving to the cloud?


• Perceived loss of control: less accessibility and visibility

- Both real & psychological hurdles about moving to the Cloud

• Perceived operational risk taken on by relying on cloud provider

• Regulatory and compliance requirements play a key role in some industries

- Fines and job loss

• Security isn’t always well understood by backup administrators

• Government access to customer data

Biggest inhibitor to Cloud adoption is security and privacy

Why?


Snapshots & Replication



How do Snapshots change backup?

Architecting the Right Storage Strategy for NetBackup

Snapshots & Replication reduce backup impact on production systems

Long term backup copies are harvested from the replica copy

Fast time to make a Snapshot copy

Replication involves block-level incremental data movement; only the changes between backups

Restores can be served from multiple sources – near-line disk to offline tape copy

Result is a backup strategy catering for space optimization and performance

NetBackup Replication Director


• Leverages array vendor’s underlying snapshot and replication technology

• End-to-end management of data lifecycle

• Application and VMware awareness

• Search capabilities

• Granular data recovery

• Monitoring, alerting, and reporting

• Single pane of glass

• Tape support for long term retention

• Integration to cloud storage targets

• Catalog indexing to enable recovery & discovery


Deduplication



Deduplication Basics


Deduplication: Technology that identifies duplicate chunks in data streams. When applied to B&R software it enables the software to only protect unique chunks - > saving storage.

*Gartner: Architecting Storage for Data Protection and Recovery, Werner Zurcher (2012)


Deduplication: Multiple Identities


Load Balancing Deduplication Media Servers


• Integrated Media Server Dedupe Pool

• Deduplication Processing occurs in media server

• NBU Media Servers/appliances acting as load balancers

• Distributes deduplication processing across multiple compute nodes

• NBU Client performs deduplication processing

• Only unique data is streamed to media servers

Deduplication: Multiple Identities Architectural Benefits


• Useful in smaller architectures – fewer NBU servers

• High load clients – Database Servers

• All-in-one appliance is a target Dedupe device

Integrated Media Server Deduplication Pool

• Environments that have many media servers

• Can increase performance

• Decreases load on storage server

Load Balancing Deduplication Media Servers

• Useful in low bandwidth environments

• High Performance, low load servers, ie file servers

Auto Image Replication

• Replicating backups between NetBackup domains

• Enables site-to-site backup image replication

• Offsite disaster recovery

• Multiple replication models supported

More to come

• Greater potential for scale helps with potential future data growth in data centers

• Significant Deduplication architectural changes have been made to allow for a scalable deduplication pool

Help manage data growth • Efficient backup of data reduces storage needs • Scalable Deduplication architecture


Backup, De-Duplication -> Appliances



What’s driving the demand: Backup complexity…


• Backup Application • Operating System • Hardware

– Servers – Disk/Dedupe Storage – Tape Libraries

How many vendors do you deal with to run your backup operations or storage operations?

• Offsite Tape Management • System Integrators


How Most Vendors Offer De-duplication for Backup


Clients

Full Backup

Backup Server Dedupe Device

What is wrong with this approach?

• Not a comprehensive backup solution; the devices are just storage targets

• Each backup is a full backup until it reaches the dedupe storage

• No bandwidth savings, backup window issue remains

• Dealing with multiple vendors, increase in complexity.
