When Faced With These Issues…Where Has IT Ended Up?
Typical answers:
Purchase more cartridges
Purchase more tape drives
Purchase more tape libraries

Data Growth– While production will grow 5x, backup typically
represents a factor of 30x production capacity
– Daily, weekly, and monthly full backups kept for months or years
Server Virtualization– VM sprawl creates protection challenges
– Server consolidation creates high server utilization leaving little bandwidth for backup; conventional backups typically move 200% of the data each week
Next Generation Virtual Data Center– The introduction of Cloud Computing, with “IT as
a Service” models, drives greater availability and resource flexibility
– Demands lower backup windows and RTO/RPO

Major trends influencing the transformation of backup environments
Why So Much Interest in Data De-dupe?
14
Backup/Recovery: Hot Spot in the Enterprise
• Secular shift from tape-centric to disk/network-centric approaches
• Enabler: massive data deduplication and compression techniques
• Unabating growth of enterprise data overwhelms legacy infrastructure
• Server virtualization another catalyst
What are your top storage initiatives?
15
Data De-duplication is Transformational
Market implications: “Gartner views this technology as transformational because it radically decreases the economics of disk-based backup and recovery.”
“…too compelling to ignore.”
Source: Dave Russell, Gartner
“By 2012, deduplication will be applied to
75% of all backups.”
Insights from Gartner
“Production deployments of deduplication for backups have progressed at an unusually high rate for such a recent technology.”
Recommendations:
“…ensure that your organization is comfortable with the robustness and maturity of the vendor's approach.”

Data De-Duplication
De-Mystifying Data Deduplication…
20EMC Corporation
EMC’s Definition of De-Duplication
“The process of detecting and identifying the unique ‘chunks’ within a given set of data, eliminating redundancy when stored or moved.”
• Uses data identification & comparison algorithms along with content addressing and indexing• Unique “chunks” are easily reconstituted to original format from the de-duplicated state
Algorithm
Before: “chunks” = 39
Data Group 1
Data Group 2
Data Group 3
After: Unique “chunks” = 6
21EMC Corporation
EMC Differentiation – Less is More
EMC Data deduplication significantly reduces:Power, Cooling, Management, Complexity
Net: The less storage needed for dedup, the bigger savings on storage.The smaller the storage footprint, the bigger the savings on bandwidth
100TB lives on 50TB
100TB lives on 33TB
100TB lives on 25TB
100TB lives on 5TB
100TB lives on 100TB
22EMC CONFIDENTIAL—INTERNAL USE ONLY
Factors Impacting De-dupe Ratios for Backup
Type of data
Small variations can have large impact
Data change rate
More user created content =
higher de-dupe ratio
Less change = higher de-dupe ratio
Retention policyLonger retention
policy = higher de-dupe ratio
More full backups = higher de-dupe ratio
Full to incremental backup ratio

While results will vary by data type and mix, Avamar can dramatically improve backup performance and efficiency
Real World ResultsDaily full backups vs. traditional daily full backups
24
Retain more
Replicate smarter
Recover reliably
Efficiently move data offsite – faster Only move deduplicated data for 99% bandwidth efficiency and cost-effective DR
Leverage end-to-end data verification Continuous fault-detection and healing ensure data recoverability to meet SLAs
Retain backups longer, using less disk 10-30x data reduction eliminates the use of tape for operational recovery
Introduce Common De-dupe Values
25
Retain. Replicate. Recover.
De-dupe everything without changing anything Never backup the same data twice
Simplify backup, archiving and DR with easy integration across workloads, infrastructures, and backup software
Revolutionize your backup by moving less data to solve your toughest VMware, NAS, and remote office backup challenges

Avamar Data Store or Avamar server
Avamar - How it Works
Global Data De-duplication Instances
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 Avamar server to determine if objects are unique
