Challenge for IT buyers of Disk with Dedupe

Backup looks like just a storage problem

Backup is a Data Movement Problem

Backup is a Data Processing Problem

Backup is a Data Storage Problem

Ten Pitfalls

9

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

Backup Implications

Block-level with

(usually on shared

server, eg. media

64K or

128KB

• Slows down backup process from

shared resources

• Uses more disk and bandwidth

• Cannot be used with multiple

backup applications

~8MB

Architectures for Recovery

12

Deduplicated data and long-term retention Latest backup retained for fast restores

Landing Zone

• Last backup stored in complete form

• Post-process deduplication

• Backups kept in deduplicated form

• Inline deduplication

Media

Server 

Ready for instant

restore—as fast as

minutes



Instant VM recovery (with

Veeam) in minutes



Fast tape copy

 Data must be “rehydrated” (reassembled) for restores  “Instant VM recovery” takes up to hours  Rehydrate data to make tape copy

 No forklift upgrades or product obsolescence

 Capacities:1TB -130TB per single GRID

 Pay as you grow, in cost-effective increments

 Forklift upgrades model to model

 Capacity and performance limited by model

 Pay more up-front, and over time

Case Study – Bird & Bird

Before

Environment

• LTO-3 tapes

• Tape backup conducted at facility separate from

main office (for security)

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

After

Environment

• 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

• 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

Case Study – TenCate

Before

Environment

• 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: 14-24 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”

After

Environment

• 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
