Today’s 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

- Test/Dev- RTO/RPO
- Growth- Static Data- Dense Files
- Server Contention- Network Contention
- Limited Resources- Limited Bandwidth

CHALLENGES
New Backup ChallengesIncreasing amounts of data that has to be protected
Traditional backup is very inefficient—does 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

De-Duplication – Why the hype?
Data De-Duplication is a ‘white-hot’ technology
Why ?
Because it has such a powerful value proposition:
Reduced StorageReduced Infrastructure
CostsMuch 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.”

DataCenter
Only unique data segments are backed up
First Instance
Data Deduplication: How it WorksSimple 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)

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 Network
‘One size’ definitely does NOT fit all!

Avamar Success Story: Corporate ExpressTime 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.”
