EMC Data Domain Efficiency Evaluation

Efficient backup systems are defined by the ability to gather data, catalog it, and store everything in a very short period of time, keeping in mind the service level agreement (SLA) and lowering the total cost of ownership (TCO). In these backup systems, EMC Data Domain enables efficient storage, receiving the data from the backup software that gathers and catalogs everything. Data Domain’s efficiency depends on several factors—how it is configured, administration activities, environmental issues, and so forth.

In this Knowledge Sharing article, Erico Silva explains how backup administrators can improve Data Domain efficiency, covering several points, such as:

• Basic items to check in an autosupport report

• Configuration guidelines for Ethernet-based backups (DD Boost, RMAN, CIFS, NFS), and SAN-based backups (VTL)

• Understanding and evaluating a Data Domain deduplication ratio

• Maintenance activities: the clean operation

• Data Domain performance analysis

The first step to meet all expectations is to understand the technology. Only then can storage administrators take advantage of its flexibility, then plan, configure, administer, and check the system continuously. This article will explain the various aspects involved while evaluating the health of a Data Domain system, thus improving the understanding of how to keep track of the technology’s efficiency.
