1 1 Technology Overview

2 2 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 60 percent of all enterprise data resides at remote offices Gartner 69% Respondents who are unhappy with current remote office backup solutions Gartner

3 3 Remote Office Branch Office Environment: Business Problem and the 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 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; 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

4 4 EMC Overview Revolutionizes the backup process with source/global data de-duplication 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 The Bottom Line Save Money On storage and network Reduce Risk & Complexity Ensure data is always in your control Address Problem Areas VMware, Remote Sites, NAS, Network Bottlenecks

5 How 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 server to determine if objects are unique Data Store or Server 5

6 6 EMC : Real-World Results Daily s vs. Traditional Daily s Data Type Amount of Primary Data Backed Up Amount of Data Moved Daily Windows file systems 3,573 GB 6.1 GB 586:1 Daily De-duplication Ratio Mix of Windows, Linux, and UNIX file systems 5,097 GB 11.7 GB 436:1 Engineering files on NAS ( backups) 3,265 GB 24.2 GB 135:1 Mix of 20 percent databases, 80 percent file systems (Windows and UNIX) 9,583 GB 80.0 GB 120:1 Mix of Linux file systems and databases 7,831 GB GB 75:1 Source: EMC While results will vary by data type and mix, can dramatically improve backup performance and efficiency!

7 7 Innovative Architecture RAIN US Patent No. 6,826,711 RAID protection from disk failures Redundant Array of Independent Nodes (RAIN) architecture Each server node with internal disk storage and CPU Grid architecture for online scalability and performance Provides server node failover and fault tolerance Replication Utilizes same de-duplication technology Daily integrity checks Available for software and Data Store Data Store Parity across storage nodes Utility and spare node Verified checkpoint

11 11 Customer Profile - Education-Regional Schools Case Study Overview 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 grid-phase 2 Replication grid added Solution Impact 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 Assessment followed by standard dedupe 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

12 12 NAS Environment: Business Problem and the Answer Business Problem SLAs for full backups/restores are often unmet Network needs and backup licenses result in higher costs Long-running backups can impact application availability and user productivity Technical Description backups can take days to complete s consume significant network and filer resources 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 times significantly reduced easier to meet SLAs Flexible recovery options enables more flexible DR solutions Reduced demand on network and filer resources

13 13 NAS Before & After, with #1 challenge for NAS clients is meeting short backup windows Traditional process - weekly full backup and daily incrementals to tape backups often exceed available window leaves data unprotected if job fails or impacts workday productivity if job continues Before Monday Tuesday Wednesday Thursday Friday Saturday Sunday Monday Tuesday Wednesday Thursday Friday Saturday Sunday 8:00 AM 9:00 AM 10:00 AM 11:00 AM 12:00 PM 1:00 PM 2:00 PM 3:00 PM 4:00 PM 5:00 PM 6:00 PM Weekend Weekend 7:00 PM 8:00 PM 9:00 PM 10:00 PM 11:00 PM 12:00 AM 1:00 AM 2:00 AM 3:00 AM 4:00 AM 5:00 AM 6:00 AM 7:00 AM Daily full 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 s immediately available for file, directory or full system restores With Monday Tuesday Wednesday Thursday Friday Saturday Sunday Monday Tuesday Wednesday Thursday Friday Saturday Sunday 8:00 AM 9:00 AM 10:00 AM 11:00 AM 12:00 PM 1:00 PM 2:00 PM 3:00 PM 4:00 PM 5:00 PM 6:00 PM 7:00 PM 8:00 PM 9:00 PM 10:00 PM 11:00 PM 12:00 AM 1:00 AM 2:00 AM 3:00 AM 4:00 AM 5:00 AM 6:00 AM 7:00 AM

15 15 Remote Office/Branch Office Commonwealth of Virginia s Department of Motor Vehicles Before 73 remote offices, backup to local, direct-attached tape drives No local IT staff Daily backup required five hours per site; six hours to restore entire server With Four hours to backup all 73 offices via existing WAN (56k-T1) to central server 45 minutes to restore entire server files restored in seconds Centralized management and control State of Virginia enabled us to reduce administrative support requirements by 80 percent, reduce backup windows by 90 percent, and recover lost files and servers in minutes rather than hours.
