Best deduplication technology tips of the year

Start the new year off right and read our best deduplication technology tips of 2010.

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.

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

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.
