3
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

4
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

5
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 Works
Global, 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

21
Avamar Solutions for VMware Infrastructure
Flexible, fast, efficient, and reliable backup and recovery
 Universal support for all vSphere 4 backup options
– Daily full guest- and image-level backups
 vStorage API integration

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.”
— Mike DePhillip,
Backup Administrator,
Virginia Department
of Motor Vehicles

26
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

27
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
 Fast, efficient daily full backups for EMC Celerra and NetApp Filers
