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

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
