Top five data deduplication technology tips of 2009

Although data deduplication is a relatively new technology in data backup environments, users quickly saw its many benefits. And its popularity continues to rise today.

Although data deduplication is a relatively new technology in data backup and recovery environments, users saw its benefits for tasks such as data reduction from the beginning. And its popularity continues to rise today. According to the Fall 2009 edition of Storage magazine's Purchasing Plans survey, 21% of respondents are using deduplication, the highest number recorded, and 26% plan to incorporate it into their plans this year. Furthermore, 38% planned to increase their dedupe spending, while only 6% anticipated reducing their dedupe budgets.

With such a new technology making its way into the data backup world and competing with tape backup, users are unsure of what to expect from data deduplication, how to incorporate it into their environments and which technologies and techniques are most suited for their data backup needs.

And you don't need to obsess over your data deduplication ratio, but you do need to test multiple dedupe systems before buying one. Here's the complete list on data deduplication dos and don'ts.

TIP #2-------------------------------------------------------------------------------------------------

Evaluating a data deduplication product for data backup and recovery
Although tape is a great way to back up data, its performance and reliability can still come up short, allowing data deduplication appliances to step in and try to outshine tape backup and data recovery. In this tip, learn how to evaluate a deduplication data deduplication product in order to decide if one is right for your data backup environment.

TIP #3-------------------------------------------------------------------------------------------------

Evaluating data deduplication products for SMBs
For small- to midsized businesses (SMBs), it can be hard to decide what data deduplication and data reduction technologies best suit their data backup environment. There are several different types of technologies such as hardware and software compression, file deduplication, block/variable block deduplication, delta block optimization, application-aware deduplication, inline deduplication, post-processing deduplication, virtual tape library (VTL) duplication and more. This tip examines the strengths and weaknesses of data deduplication products for SMBs and how to go about choosing the best one for your organization.

TIP #4-------------------------------------------------------------------------------------------------

Data deduplication technology: The business case for dedupe
Many storage administrators and backup administrators question whether data deduplication will meet all of their data backup needs.
