Todays Data Protection Challenges IDC: forecasts 10x data growth in the next 3 Years 10 TB production data will grow to 100 TB Your 40TBs/month of backups turns into 400 TB per month Including your monthly backups, this will grow to over 1.5 PB in backup storage This is a two-fold problem: Inability to meet your SLAs for backup and recovery Storage and associated operational costs increasing faster than available budgets Forrester: 65% of companies will adopt server virtualization by 2009 Backup bottleneck limiting customers from further server consolidation ESG: 47% of companies consider improving ROBO backup a high priority Cost of people and equipment at each location Bandwidth too costly for centralized backup with traditional methods Risk that backups not happening at all ESG: up to 14% of backups are incomplete Data is unprotected, your business is at risk 4 Copyright 2009 EMC Corporation.

CHALLENGES New Backup Challenges Little idle CPU, memory bandwidth, and I/O capacity for backup Virtual Server A Virtual Server B Virtual Server C Old Paradigm Physical Environment: Low overall server utilization and plenty of bandwidth for backup New Paradigm Virtual Environment: High overall server utilization and little bandwidth for backup 20 percent resource utilization80 percent resource utilization 100% 80 % 40% 0% 60% 20% CPU Utilization 100% 80 % 40% 0% 60% 20% CPU Utilization Server AServer BServer C ESXServer Hardware Shared Physical Resources 6 Copyright 2009 EMC Corporation.

Resource Pool VMware Virtualization Layer x86 Architecture ~200% weekly per virtual machine Disk/Tape CHALLENGES New Backup Challenges Increasing amounts of data that has to be protected Traditional backup is very inefficientdoes nothing to eliminate redundant data Redundant data along with weekly full and daily incrementals results in up to 200% of primary data being backed up per week Does nothing to solve network, backup server, or disk bottlenecks OS Backup Server 7 Copyright 2009 EMC Corporation. All rights reserved. De-Duplication Why the hype? Data De-Duplication is a white-hot technology Why ? Because it has such a powerful value proposition: Reduced Storage Reduced Infrastructure Costs Much Faster Backups Efficient Replication for DR All of which adds up to a compelling TCO & ROI De-Dupe Defined: Identification of unique chunks in a set of data, enabling the elimination of duplicates when stored or moved. De-dupe is a feature not a product. It is just one feature--albeit an important one--of disk-based platforms. 8 Copyright 2009 EMC Corporation. All rights reserved. Data Center Only unique data segments are backed up First Instance Data Deduplication: How it Works Simple Example of Global, Source Data Deduplication Remote Site 2 Modified Instance New data segment identified and backed up Remote Site 1 Duplicate Instance Data already backed up, so only unique IDs stored (20 byte pointers) EMC BACKUP SOLUTIONS Deduplication Server (stored backup data) A B C D A B C D E E 9 Copyright 2009 EMC Corporation. All rights reserved. DE-DUPLICATION AT TARGETDE-DUPLICATION AT SOURCE Where Can Data De-duplication Occur? Source Client software agents identify repeated sub-file data segments at the source Only new, unique segments are transferred across the network during backup operations Benefits: shorter backup window, lower bandwidth requirements Target Backup application sends native data to a target storage device Data is de-duplicated once it reaches the target & can happen during or after backup Benefits: transparency to backup application, plug and play experience Network One size definitely does NOT fit all! 10 Copyright 2009 EMC Corporation.

Avamar Success Story: Corporate Express Time shortened, costs reduced for backup in VMware deployment Before Avamar Storage demands were rapidly increasing Tape library was reaching slot capacity and upgrading was not ideal due to age and maintenance costs Needed to control costs and simplify data management Backup and disaster recovery was time consuming With Avamar Reduced stored data by more than 50%, from 92 TB to 44 TB Achieved significant financial savings Enabled disk-based backups to be completed in 30 minutes, compare to 6 hours in the past for tape Reduced restoration times for business-critical data from 24 hours to minutes EMC BACKUP SOLUTIONS We were blown away by the simplicity of the management interface and the comprehensive capabilities offered by Avamar. After carrying out a proof of concept, we clearly understood the benefits Avamar would bring to our business. Mark Jones Technology Infrastructure Mgr.
