Summary


Today’s Data Protection Reality

Data growth is immense Companies want more data protected Time required for backup is expanding Backup hampered by tape’s unreliability

and poor performance Virtual machines pose unique backup

challenges Increasing volume of data at remote

offices More data stored locally on desktops

and laptops

Pressure to meet the changing needs of the business


The Usual Answers

Backup to tape, or stage to disk, and then archive to tape

Manually move tapes offsite for disaster recovery

Traditional backup and recovery Inefficient and slow, ~200% of primary

data moved across the network weekly Tedious, multi-step recovery process Risks the loss or theft of unencrypted

tapes in transit Data is difficult to recover and leverage


Avamar Overview

Backup and recovery software with integrated global, source data deduplication Reduces the size of backup data at the source—

before it is transferred across the network Delivers fast, daily full backups using existing infrastructure Reduces network bandwidth for backup by up to 500 times Deduplicates across sites and servers, reducing total

backup disk storage by up to 50 times Cost-effectively stores daily full backups on disk—reducing

or eliminating the need for tape Ideal for protecting VMware environments, remote offices,

LAN/NAS servers, and desktop/laptop systems

Avamar: How it WorksGlobal, sub-file data deduplication

At the source—Deduplication before data is transported across the network

At the target—Assures coordinated deduplication across sites, servers, and over time

Granular—Small, variable-length sub-file segments guarantee most effective deduplication

Send and store each atom only once

Avamar’s Optimized Backup for VMware Infrastructure

Optimal location: Reduces data at the source– Data deduplicated at VM guest or proxy server (source)– Duplicated data never traverses congested shared physical resources– Data moved during backup is reduced from ~200% to ~2% of primary data

weekly– Deduplicates data globally across virtual machines and/or VMDK (virtual

machine disk) format files

Optimal granularity: Sub-file, variable-length segments– VMDK is one large file; any changes cause an incremental/full traditional

backup– Fixed-length segment deduplication solutions fail due to frame offset– Avamar efficiently moves only new, unique variable length data segments

Ideal for the protection of VMware environments– Delivers fast, daily full backups over existing virtual and physical infrastructure– Enables greater server consolidation by eliminating backup bottlenecks– Maximizes value from VMware

Avamar deduplicates at the optimal location and level of granularity


Avamar Solutions for VMware InfrastructureFlexible, fast, efficient, and reliable backup and recovery

Universal support for all vSphere 4 backup options– Daily full guest- and image-level backups

Remote Office/Branch Office (ROBO) Backup challenges and Avamar solution

The “Achilles’ heel” of data protection– More than 4 million remote offices in the U.S.– Remote office data growing at more than 50% per year* – Most back up to tape and move unencrypted tapes offsite– Often unskilled, untrained IT staff at remote sites

Avamar remote office/branch office backup is simple, safe, and manageable

– Extend data center protection to the edge– Fast, daily full backups and one-step recovery through

existing WAN/LAN links– Avamar agent-only deployment for smaller offices (no extra

local hardware)– Eliminate distributed tape management/infrastructure– Mitigate risk involved with manually shipping tapes– Data encrypted in-flight and at-rest for security

*Source: Gartner

“Avamar enabled us to reduce administrative support requirements by 80%, reduce backup windows by 90%, and recover lost files and servers in minutes rather than hours.”

Virginia Department of Motor Vehicles


NAS Filer Backup and Recovery Challenges

Limited backup windows– Daily full backups desired, but not feasible

Limited backup and recovery performance– Single filer controllers have limited resources and can

become a bottleneck – Incomplete backups leave data at risk

Limited network links and disk storage– Redundant data limits performance of network/

infrastructure and requires more disk storage

Impact on end users– When backups exceed allotted window, end users compete

for the NAS resources (poor response, lower productivity)

NDMP licenses– Traditional NAS filers require expensive NDMP licenses to

support backup and recovery


Avamar NAS/NDMP Backup Accelerator

How it works– Avamar Accelerator uses NDMP to communicate to source NAS device– Accelerator requests only modified data daily– Accelerator performs source-based deduplication on modified data

Only new modified segments are sent to Avamar Data Store – Source and global deduplication occur at Accelerator

Avamar’s NDMP backups are ready for immediate recovery– Avoids time-consuming task of restoring weekly full, plus daily incremental, backups
