Virtualization Value

Server consolidation and infrastructure optimization

– Pools common infrastructure resources– Breaks legacy “one application to one server”

Physical infrastructure cost reduction– Reduces hardware, real estate, power and

cooling costs

Improved operational flexibility and responsiveness

– Reduces time spent on provisioning, configuration, monitoring, and maintenance

Increased application availability and improved business continuity

– Eliminates planned downtime

“Virtualization will be the most impactful trend in infrastructure and operations through 2010.”

— Gartner*Source: Gartner, Virtualization Will Drive Major Change in IT Infrastructure and Operations in the Next Three Years, May 8, 2007


New Backup Challenges

OLD PARADIGMLow overall server utilization and plenty of

bandwidth for backup

NEW PARADIGMHigh overall server utilization, but

little bandwidth for backup

Virtualization Changes Server, Application, and Information Paradigm…Backup Must Evolve to Deliver Even Greater Consolidation and Value


Introducing EMC Avamar

Reduces the size of backup data at the source—before it is transferred across the network—reducing backup times by up to 10 times

Reduces required network bandwidth—and the amount of data backed up daily—by up to 500 times

De-duplicates across sites and servers for maximum efficiency

Cost-effectively stores a greater number of full backups on disk—reducing or eliminating the need for tape

Ideal for protecting remote offices, VMware environments, LAN servers in the data center—enabling fast, reliable, and secure backups over existing network connections

Revolutionizes Backup with Global, Source Data De-duplication

Avamar: Optimized Backup for VMware Infrastructure

Optimal location: Reduces data at the source– Duplicate data never traverses congested shared resources– Data backed up is reduced from ~200 percent to ~2 percent of primary weekly– Significantly reduces contention for shared resources– De-duplicates within and 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 de-duplication fails due to frame offset– Sub-file, variable-length segment de-duplication finds changes anywhere in VMDK– Dramatically cuts the amount of data backed up daily– Significantly reduces daily backup time

Ideal for the protection of VMware environments– Enables fast, secure backups over existing virtual infrastructure– Permits greater server consolidation and maximum value from VMware

Avamar De-duplicates at the Optimal Location and Level of Granularity


Avamar Data Store or Avamar server

How Source De-duplication Works

Global Data De-duplication Instances

Client agent scans the data for changes

Modified files broken into sub-file variable length segments

Only unique sub-file segments are backed up

Queries local file cache to identify and disregard static files

Compresses and applies a hash to each object

Queries local hash cache, and then the Avamar server to determine if objects are unique


Remote Site 1Duplicate Instance

Data already backed up, so only unique IDs stored (20 byte pointers)

Avamar: Backup Built for VMware

VMware and Avamar—technologies that align perfectly– Virtual environments provide great opportunities for source de-duplication– Avamar is the best and most versatile solution for these environments

VMware adoption is a good time for a fresh look at backup and recovery– The perfect opportunity to consider Avamar and de-duplication– Achieve higher levels of consolidation without backup bottlenecks


Backing Up VMware Infrastructure

Before AvamarData center re-design focused on server consolidation and virtualizationConcern about traditional, tape-based backup in VMware environmentBackup windows strained; physical resources overburdened

With AvamarDeployed agents within virtual machines95 percent reduction in data moved90 percent reduction in backup timesMajor reductions in NIC, CPU, and memory usageCentralized management and control

“Avamar provides a huge time and cost savings for backup of multiple virtual machines.”

With Avamar, we can centrally manage all of our backups, and we also gain the ability to rapidly restore data down to the file level.”

— Curtis Damhof, Network Manager, St. Peter’s Health Care Services


Global Industrial Manufacturer

Before AvamarStruggling to meet backup, recovery, and reliability goals

Shipping tapes offsite—risky, slow recovery

With AvamarBackup for VMware (24 ESX Servers, 332 virtual clients)

Backup performance increased tenfold

Backup network traffic reduced by 95 percent

Reduced backup and recovery administrative burden

Eliminated physical tape management

Before AvamarGrowing VMware environment struggles to meet backup windowDaily tape backup and offsite tape shipments—risky, slow recovery Unable to quickly replicate data via WAN for disaster recovery

With AvamarGlobal de-duplication effective within and across VMDK filesOver 70 percent reduction in first backup and average of 99.7 percent thereafter Compared to traditional alternatives, testing showed…

– Avamar moved one-fifth of the data that Symantec PureDisk moved

– Avamar moved 190 percent less data than traditional tape backup software moved
