Data deduplication reduces storage space by eliminating redundant data in your backup environment. It's also become one of the hottest data backup and recovery technologies in the past few years. According to enterprise data storage managers responding to SearchStorage.com's "Storage Priorities for 2010" survey, data deduplication was the most important data backup technology with 61% either deploying or evaluating it on top of the 23% current dedupe users.
To help you start the new year off on the right foot, we've gathered our best deduplication technology tips of 2010. Start off by reading our tutorial, and then drill down deeper by learning about on dedupe in virtual environments, global deduplication and more.

Data
deduplication technology tutorial
As indicated by the Storage Priorities survey, interest in data deduplication isn't showing any
signs of slowing down. But there's a lot that goes into choosing the best dedupe product for your
company. In this data backup tutorial, learn about global data deduplication, what to look for in a
data deduplication product, inline vs. post-processing deduplication, and more. You will also learn
what kind of data deduplication ratio you can expect and the pros and cons of popular data
deduplication approaches. Click here to read the tutorial on data
deduplication technology.

Implementing
data deduplication technology in a virtualized environment
In this Q&A with Jeff Boles, senior analyst with the Taneja Group, learn about why
organizations are more interested in data dedupe for server virtualization, whether target or
source deduplication is better for a virtualized environment, what to watch out for when using
dedupe for virtual servers, and what VMware's vStorage APIs have brought to the scene. Click here

Source-based
deduplication tutorial
Julian Cooper, senior IT administrator at Integrated Control Corp, recently deployed source-based
deduplication after an overhaul of the medium-sized businesses' backup strategy. The company was
performing backup to tape but was struggling with slow restores and failed backups. After moving to
a disk backup approach, Cooper began looking for ways to reduce backup data, and considered both
data deduplication and archiving. In this tutorial, learn about the pros and cons of source
deduplication, source vs. target dedupe, and more. Click here to read the tutorial on source-based
deduplication.
TIP #4-------------------------------------------------------------------------------------------------
Restoring
deduped data in deduplication systems
Restores from some data dedupe systems can be slower than modern tape drives, and restores from
other deduplication systems can be faster than tape could ever dream of. In this column, you will
learn what you need to do to make sure your dedupe system is on the right side of those two
extremes. Click here to read about problems with restoring
deduped data and to learn how you can prevent them.

Deduplication
best practices
While the overall data deduplication concept is relatively easy to understand, there are a number
of different techniques used to accomplish the task of eliminating redundant backup data, and it's
possible that certain techniques may be better suited for your environment. So when you are ready
to invest in dedupe technology, consider the following technology differences and data
deduplication best practices in this tutorial to ensure that you implement the best solution for
your needs. Click here to learn about the most important deduplication
best practices.
