AVAMAR SOFTWARE

Avamar Overview

Reduces the size of backup data at the source, enabling fast, daily full backups across existing physical and virtual infrastructure

– Reduces daily backup times by up to 10x reduction

– Reduces daily network bandwidth impact by up to 500x

De-duplicates across sites and servers for maximum efficiency

– Reduces total disk backup storage by up to 50x

Cost-effectively store full backups on disk for extended period of time – reducing/ eliminating reliance on tape

Ideal for protecting VMware environments, remote offices, and data centers constrained backup windows or limited bandwidth

Revolutionizes backup with global, source data de-duplication

Avamar: How it Works

Global, Source Data De-duplication

At the source—De-duplication before data is transported across the network

At the target—Assures coordinated de-duplication across sites, servers, and over time

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

Send and store each atom only once

Avamar’s 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 reduces the amount of data moved during daily backups– 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

Backing up VMware Infrastructure

Before Avamar Data center re-design focused on server consolidation

and virtualization

Concern about traditional, tape-based backup in VMware environment

Backup windows strained; physical resources overburdened

With Avamar Deployed agents within virtual machines

95 percent reduction in data moved

90 percent reduction in backup times

Major reductions in NIC, CPU, and memory usage

Centralized 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

15EMC CONFIDENTIAL—INTERNAL USE ONLY

Backing Up VMware Infrastructure

Before Avamar Struggling to meet backup, recovery, and reliability goals across

extended enterprise

Lengthy backup windows caused by increasing data volumes threatening network performance

Expanding existing backup solution would require –-second master server, 2 additional tape silos, 16 new LTO tape drives

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

Avamar agents installed in VM Guests

Eliminated physical tape management

Reduced backup and recovery administrative burden

Backup performance increased tenfold

Backup network traffic reduced by 95 percent

Global Industrial Manufacturer

“Avamar was much less expensive than our other backup and recovery options. But it also provides us faster data restores, more backup capacity, and scalability to meet future data protection needs”

— Company Spokesman, Global Industrial

Manufacturer

16EMC CONFIDENTIAL—INTERNAL USE ONLY

Backing Up VMware Infrastructure

Before Avamar Growing VMware environment struggles to meet backup

window

Daily tape backup and offsite tape shipments – risky, slow recovery

Unable to quickly replicate data via WAN for disaster recovery

With Avamar Global de-duplication effective within and across VMDK

files

Over 70% reduction in first backup and average of 99.7% thereafter

Compared to traditional alternatives, testing showed: – Avamar moved 1/5th of the data that Symantec PureDisk moved– Avamar moved 190% less data than traditional tape backup software

Fortune 20 Healthcare Supplier

17EMC CONFIDENTIAL—INTERNAL USE ONLY

Remote Office/Branch Office Backup

Before Avamar Strain developing and deploying a coherent IT strategy

for over 250 sites, 100,000 employees– Lacked consistent IT infrastructure– Cumbersome tape backup solution was overextending staff and

overtaxing virtual machines

Escalating capital and operation costs

With Avamar Deployed from templates within a virtual application pack

Reduced backup time by 75% or more, slashed cycle time for offsite data replication

Minimized impact on network bandwidth

Reduced storage costs by eliminating tape backup and slashing storage requirements

A Global Pharmaceutical Company

“When we compared the total cost of ownership of EMC Avamar to that of traditional backup, we found that EMC Avamar costs less yet provides exponentially better data protection and service levels.”

— Head of Storage Services

Avamar Guest vs. Avamar VMDK Backup Results

Additional Takeaways:

• Average backup data commonality identified by EMC Avamar:• Avamar Guest backups = 99.6%

• Avamar VMDK backups = 97.9%

• Therefore, Guest backups moved just .004 while VMDK moved .021 (Guest backup was 5x more efficient in this example)

• Avamar Guest and VMDK backups are both extremely efficient!
