Growth of Remote Offices

Remote offices are growing rapidly– Over 4 million remote offices in the US

– No “standard” remote office size, data, staff, network, etc.– The average branch has between four and six servers - Nemertes Research

Business data no longer resides solely in the data center

Remote office data protection: costly, time consuming

Sometimes non-existent

69%69% Respondents who are unhappy with current remote office backup solutions

— Gartner

“60 percent of all enterprise data resides at remote offices”

Remote Office Branch Office Environment: Business Problem and the Avamar Answer

Business Problem– Mgmt and business risk – significant amount of ROBO data unprotected– Remote data growing rapidly; internal/external regulatory compliance requirements

Technical Description– Local tape-based backup is typical – WAN constraints; tape shipping for DR; non-technical local staff; ad-hoc processes

Avamar Answer - Combine local office data protection with DR and centralized management and control.

– De-dupe at the source for fast, daily fulls via existing WAN (most cases) – Flexible deployment - agent only for smaller ROBO sites; Avamar Virtual Edition– Meet strict SLA’s, centralized management, data encrypted in flight & at rest

Results to the customer– Improved SLA for remote office backup / restore and data integrity– Improved reporting and security – Reduced mgmt spend in remote sites and datacenters– Reduced or avoided WAN costs

EMC Avamar Overview

Radically reduce the size of backup data– At the source (client) – before it is transferred

across the network and stored to disk– Dramatically reduces required bandwidth– Cuts backup time by up to 10X

De-duplicate & manage globally – Across sites & servers for maximum efficiency

Reduce tape dependence – Cost-effectively store more full backups on disk

Fast, secure, backups – Via existing physical & virtual infrastructure

Revolutionizes the backup process with source/global data de-duplication

The Bottom Line

Save Money– On storage and network

Reduce Risk & Complexity– Ensure data is always in your control

Address Backup Problem Areas– VMware, Remote Sites, NAS, Network

How Avamar Data De-duplication Works

Source / Global Data De-duplication

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

Customer Profile - Education-Regional Schools

Challenge (20TB Environment)

– Customer having significant challenges meeting backup windows at 200 Schools. 5 hour backup window per school

– Lack of centralized backup control and policies resulting in remote backup failures and missed backups

Solution– Phase 1 Single Avamar grid-Phase 2

Replication grid added

Solution Impact– Backup of all schools under central policy

control resulting in successful backups

– Central identification of any failed backups

– All 200 schools backed up in 5 hours vs 5 hours per school using local backup

– Elimination of tape processes and associated costs

Sales Strategies– Campaign started with a Backup

Assessment followed by standard de- dupe presentation

– Developed a TCO model to prove the value of solution

– Standard backup control and policy over all remote school locations

– Fast backups across all schools

NAS Environment: Business Problem and the Avamar Answer

Business Problem– SLAs for full NDMP backups/restores are often unmet– Network needs and NDMP backup licenses result in higher costs– Long-running backups can impact application availability and user productivity

Technical Description– Full NDMP backups can take days to complete– Backups consume significant network and filer resources

Avamar Answer – Faster NAS backups with fewer resources consumed– Eliminate full backups while offering simple one-step recovery– True centralized management of NAS backups– Reduce tape infrastructure, media and handling costs

Results to the customer– Backup times significantly reduced – easier to meet SLAs– Flexible recovery options enables more flexible DR solutions– Reduced demand on network and filer resources

#1 challenge for NAS clients is meeting short backup windows

Traditional process - weekly full backup and daily incrementals to tape

Full backups often exceed available window – leaves data unprotected if job fails or impacts workday productivity if job continues

Daily full NDMP backups - up to 10x faster than traditional methods

Enables daily full backups and eliminates need for incrementals

Meet short backup windows to protect critical NAS data

Backups immediately available for file, directory or full system restores
