� Q&A

Remote Office & Branch Offices (ROBO) Challenges

� ROBO’s face the same information infrastructure challenges as the data center� Data protection� Security and compliance� Storage consolidation

� Branch offices often lack data center best practices� Difficult to leverage data center investments at the

Complexity

As much as 75% of your corporate data may live at remote sites

� Difficult to leverage data center investments at the branch

� Information growth at remote sites has made costs difficult to control

� Challenges are even more complex due to network dependency� Network topology and connectivity impact remote

operations� Increasing WAN connections is a costly solution for

remote user performance

Availability

Efficiency

Typical ROBO Environment

� Too many servers (~ 5 to 10)� Limited space, power and cooling� Each server adds to maintenance costs

� Management complexity� Most sites lack server administrators� Outsourcing is an imperfect solution� Supporting legacy operating systems can be a key challenge

� Speed and ability to deploy new applications

WAN

RemoteOffice

RemoteOffice

RemoteOffice

� Speed and ability to deploy new applications� Redundant and often inconsistent hardware and software� Adding applications requires additional hardware and space� New hardware needs to be provisioned at HQ or requires HQ

support

� Data protection� High data redundancy that can degrade application performance,

result in inefficient storage utilization� Host failure recovery is tedious and time consuming� Data security and compliance is at risk with tape backups

HQ Data Center

Centralized

Simplify IT Management

� Standardize on a single virtual server platform

� Remotely and centrally manage from the Data Center

� Accelerate provisioning

Ensure Availability and Recoverability

Empowering ROBO with Virtualization

Improve management and protection of your remote offices

Business

Continuity

Cost Savings

� Guarantee uptime

� Automate backup and restore

Reduce Hardware and Operational Costs

� Minimize costly setup and support trips

� Reduce operational costs

� Deploy new applications without adding any Hardware

Centralized VirtualizationEnable remote offices to access virtual machines on centralized server hardware in the data center

�Maximizes server consolidation ratios, cost savings

Two Approaches for Virtualizing ROBO

Distributed VirtualizationVirtualize servers and desktops at the remote office and remotely manage them from the data center

�Maintains application performance regardless of WAN speed and availability

Centralized Server & Desktop Deployments

Centralized Deployments

> Remote/branch sites access virtual machines on centralized server hardware in the data centercenter

> Maximize server consolidation and cost savings

> Reduced management & support problems

Consideration �Is your centralized backup

infrastructure prepared to protect all of this new data?

Distributed Server & Desktop Deployments

Distributed Deployments

> Virtual servers and desktops reside at the remote/branch site.

> Maintain application performance regardless of WAN regardless of WAN speed or availability

> Centralized and remote management

> VDI

Consideration �Is your distributed backup

infrastructure prepared to efficiently protect this remote data?

AVAMAR: Backup & Recovery with Source-based Data De-duplication

� Global, source-based data de-duplication defuses the explosion of backup data

� Radically reduces the media, network, and time required for backup

� Alters the fundamental economics of disk versus tape

DE-DUPLICATION AT THE

SOURCE

10

disk versus tape

� Accelerates shift to disk as primary medium for backup

� An alternative to archaic IT processes (shipping tapes to disaster recovery)

� Automated, encrypted remote copy over existing WANs

THE TRADITIONAL BACKUP PROBLEM �

Backup Server

Disk / Tape

� All data must pass through the shared resources

� Traditional backup is very inefficient – does nothing to eliminate redundant data.

� De-duplication at the “source” solves both centralized and distributed remote office backup issues

How Source-based De-duplication WorksGlobal data de-duplication instances

� Client agent at the source scans the data for changes

� Modified files broken into sub-file variable length segments

� Only unique sub-file segments are backed up

Avamar Data Store or Avamar Server

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

What If You Can’t Change Your Environment?

DE-DUPLICATION AT THE

TARGET

Backup application sends native data to a target storage device

Data is de-duplicated once it reaches the target

De-duplication can happen

Backup and recovery with target-based de-duplication

De-duplication can happen during or after backup

Found in VTLs or LAN B2D appliances

Transparency to backup application offers users a “plug and play” experience
