SYMANTEC VISION 2014
But I thought tape was dead?
Architecting the Right Storage Strategy for NetBackup 5
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
SYMANTEC VISION 2014
• 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
Architecting the Right Storage Strategy for NetBackup 7
“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%+

What are they doing? Who is using it?
Cloud as Storage
Architecting the Right Storage Strategy for NetBackup 9
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

Why aren’t IT Organizations moving to the cloud?
Architecting the Right Storage Strategy for NetBackup 10
• 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?
SYMANTEC VISION 2014
Snapshots & Replication
Architecting the Right Storage Strategy for NetBackup 11
SYMANTEC VISION 2014
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

Deduplication
Architecting the Right Storage Strategy for NetBackup 15
SYMANTEC VISION 2014
Deduplication Basics
Architecting the Right Storage Strategy for NetBackup 16
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.

Deduplication: Multiple Identities
Architecting the Right Storage Strategy for NetBackup 17
Load Balancing Deduplication Media Servers
Client Side Deduplication
• 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

What’s driving the demand: Backup complexity…
Architecting the Right Storage Strategy for NetBackup 25
• 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
SYMANTEC VISION 2014
How Most Vendors Offer De-duplication for Backup
Architecting the Right Storage Strategy for NetBackup 26
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.
