1 Disk Backup with Data Deduplication ABOUT DISK BACKUP WITH DEDUPLICATION

2 What appears to be simple & straightforward Built for Backup is often more complex & risky than you think. 2

3 Agenda Backup paradigm shift and challenge for IT buyers 10 potential mistakes and pitfalls Key considerations Overcoming the barriers: ExaGrid disk with dedupe TenCate disk backup story Q & A 3

4 Paradigm Shift to Disk with Deduplication Traditional Tape- and Truck-centric Transitional Disk and Tape Next/Current Generation Disk with Deduplication Disk backup with deduplication onsite, optionally replicated to second site

5 IT Issues, Needs Driving the Paradigm Shift IT Management Issues! Backup Window! Server Virtualization! Longer Retention! Storage Costs! Do More with Less Disk Backup with Deduplication 5 Backup & Recovery Needs Fast Backup Times Fast Restore Times and Instant Recovery Fast Offsite Disaster Recovery Reliable Backup & Recovery, No Failure Points Low Total Costs & Management Burden

6 Backup and Recovery Statistics Percent of IT professionals feel their data is vulnerable Percent of IT pros challenged by long backup windows Percent of IT is challenged to get more reliable DR 7 Hours on avg. to recover from data protection incident 6

7 Disk Backup with Deduplication. What if you had

8 Challenge for IT buyers of Disk with Dedupe Backup looks like just a storage problem Built for Backup Backup is a Data Movement Problem Backup is a Data Processing Problem Backup is a Data Storage Problem Simply combining disk and deduplication is not the answer. That can lead to

9 Ten Pitfalls 1. Missing support for your backup apps and utilities 2. Missing support for key features of your backup app 3. Expanding backup window as data grows 4. Costly forklift upgrades as data grows 5. Slow restores of traditional full backups or images 6. Slow offsite tape copy 7. Instant Recovery of VMs takes hours vs minutes 8. High cost for increased equipment needs over time 9. Constant extra disk purchases from poor dedupe ratio 10.Expensive bandwidth from poor deduplication ratio 9

10 Key Disk with Deduplication Considerations Deduplication approach and efficiency Architecture for recovery Architecture for scaling as data grows 10

11 Deduplication Approach, Efficiency Approach Block-level with fixed block length (usually on shared server, eg. media server) Zone-level with byte change (on target side appliance Block-level (on target side appliance) Block Size 64K or 128KB Average Data Reduction 7:1 ~8MB 20:1 ~8KB 20:1 Backup Implications Slows down backup process from shared resources Uses more disk and bandwidth Cannot be used with multiple backup applications Faster backups and restores Most efficient disk, bandwidth Supports multiple backup apps and utilities Faster backups Most efficient disk, bandwidth Supports multiple backup apps and utilities 11

12 Architectures for Recovery Backups kept in deduplicated form Inline deduplication Landing Zone Last backup stored in complete form Post-process deduplication Media Server Data must be rehydrated (reassembled) for restores Instant VM recovery takes up to hours Rehydrate data to make tape copy Media Server Ready for instant restore as fast as minutes Latest backup retained for fast restores Instant VM recovery (with Veeam) in minutes Fast tape copy Deduplicated data and longterm retention Deduplicated data, long-term retention 12

15 While there are a number of well-known vendors with very strong product offerings in this space ExaGrid's unique scale-out grid architecture and truly refreshing support model set it apart from the pack and place it in a class of its own... Matt Prigge, Writer, InfoWorld 15

16 Implementation Simple and Flexible SAN Storage Remote Offices NAS Storage DAS Storage MAN/WAN servers Database servers File servers VMware servers App. servers Fast Installation: under 2 hours over the phone SQL Dumps RMAN, TAR Gigabit/10 Gigabit Ethernet VMware Veeam vranger Backup Server Offsite Tapes ExaGrid Primary Backup Site MAN/WAN Tape Library Optional ExaGrid DR Site or remote data center 16

17 ExaGrid Zone-Level Deduplication 20:1 up to 50:1 typical data reduction 50 TB of backup data Stored in 3.5 TB with deduplication TB Stored Conventional Disk Storage Savings ExaGrid Disk Backup with Deduplication Number of Backup Jobs 17

18 Backup Performance: Fastest Backups Inline Solutions Media Server ExaGrid Post-Processing 2-3X Faster Than Inline 30-90% Faster Than Tape Backup directly to disk Unique landing zone architecture Post-process zone-level data deduplication No in-line processes to slow backups Shortest possible backup window DISK Post-process deduplication Shorter Backup Window DISK 18

19 Fastest Restores: Physical and Virtual Servers Built for Backup Inline Solutions ExaGrid Landing Zone, Post-Processing Media Server Deduplicated Data and Long-term Retention Latest backup retained for fast restores Latest backup stored in complete form Ready for instant restore as fast as minutes Instant VM recovery (with Veeam) Fast tape copy Efficient restore of earlier versions Byte-level changes quickly merged to latest backup Seamless to backup application Can restore from any historical version 19

22 On-site and Off-site Tape Replacement Optimizes most recent backups for Instant DR Avoids delays from restoring from tape Restores faster from full copy vs rehydrating data Example: 10TB Backup 5TB (last backup least deduplicated) 5 TB 200 GB 5 TB GB 5 TB 200 GB 200 GB Updated to Last Backup 22

23 ExaGrid at a Glance Company Offices across North America, Europe, APAC Product Highly scalable, costeffective disk backup with deduplication system 5,000+ Systems installed globally 300+ Customer success stories and videos at ExaGrid.com Technology certifications and compatible 20+ backup applications & utilities 23

24 Case Study Bird & Bird Environment Before LTO-3 tapes Tape backup conducted at facility separate from main office (for security) Environment After 20TB ExaGrid in London; 1TB in Hong Kong Daily incremental and weekly full to ExaGrid, archive to tape once a month 3-8 weeks of backups kept on ExaGrid systems Backup and Restore Speeds Full backup started Friday ran into Monday- Tuesday Hours to restore from backup tapes Time to complete weekly full meant could not restore wile tape in use Backup and Restore Speeds Backup window reduced by nearly 50% Restores in minutes vs hours previously We now have the ability to provide any of our users with a near instant restore. This is satisfying to us in the IT team and really helps us to deliver an excellent service. Our users can be confident that the technology is behind them to deliver world class service to their clients and never waste another billable hour again. Jon Spencer Infrastructure Manager, Bird & Bird 24

25 Case Study TenCate Environment Before Originally backing up 100% physical servers to tape; switched to EMC Data Domain # servers grew by 5X over 3 years from move to 99% virtualized servers Backup Situation Backup windows: hours; some backups would not complete Required manual deletion of files every day. Retention down to 5 days; wanted 4 weeks Cost to Upgrade Several hundred thousand dollars for forklift upgrade Environment After ExaGrid 2-site system Deduplication ratios: 13:1 to 78:1. Backup Situation Backup window reduced from 24 to 8 hours Fastest restores no need to rehydrate data Retention increased from 5 days to 4 weeks Automated cross-replication to second site protects against data loss Cost: Avoided forklift upgrade; cost effective as data grows--add capacity in modular increments I learned about forklift upgrades and how much it was going to cost me. I couldn t believe it. We re trying to use our budget intelligently, and that s not intelligent to me. I turned to my reseller because I trust him, and he told me that they re no longer recommending Data Domain and that I should look at ExaGrid. Jayme Williams, Sr. Systems Engineer, TenCate 25
