Mr. Jensen

What does “dedupe–rate” mean?

What data can be deduplicated?

Where to run deduplication?

(4)

What is Deduplication?

• How does it work?

• What is the difference between file and block level?

What Does “dedupe–rate” Mean?

• Data deduplication ratio over a particular time period

(7)

What Does “dedupe–rate” Mean?

Space Reduction Ratio

Space Reduction Percentage

2:1

1/2 = 50%

5:1

4/5 = 80%

10:1

9/10 = 90%

20:1

19/20 = 95%

• Comparing ratios is problematic

–

Broad set of assumptions implicit in their calculation

100:1

99/100 = 99%

NetBackup to Target Dedupe Devices

• Deduplicate at the appliance

• Benefits include:

–

Easy setup, no change to backup environment

–

Centralized policy management and replication

control

Target Dedupe Devices

Client

• Disadvantages:

–

Workload of a traditional backup until backup

data hits appliance — no infrastructure savings

–

Cost

Backup Re-architecture—Strategic Objectives

—

Eliminate tape as a transported media

—

Establish ‘always on’ WAN connectivity to recovery sites

—

Improve RTO/RPO—narrow the gap of tier 1 disk replication

—

Provide ‘always ready’ disaster recovery infrastructure

—

Provide operational consistency even in case of disasters

The Three Key Facilitators…

—

Data Deduplication technology coupled with highly efficient Data

Replication

—

3-site DR model – Primary, Secondary/Recovery, Data Bunker

Summary - One size does not fit all…

• Customers often need more than 1 approach to deduplication

–

Client / Source Deduplication

–

Media Server Deduplication (Inline)

–

Target Appliance Deduplication (Post process)

• Each use case is different

• Each customers data is different

• Each customers approach towards Data Protection is different
