While data deduplication and data compression are two data reduction techniques that are widely used in data backup environments, up until recently, they weren't considered practical for a primary storage environment. Primary storage data reduction often brings a performance penalty, and the potential for savings is much smaller. Now, though, users are becoming more interested in the technology as they look for more help in controlling data growth in their storage environments.
To help you decide if data reduction is right for your primary storage environment, SearchStorage.co.UK has compiled some recent information on primary storage deduplication and compression. First, we'll take a look at exactly why these technologies are gaining interest in the storage industry. Second, we'll help you to better understand data dedupe for primary storage by explaining what types of data are suitable for primary storage and the different types of data deduplication. Third, we'll examine how data reduction on primary storage can reduce your data footprint. And last, we'll provide you with a list of vendors currently offering primary storage data reduction technologies.
Many vendors and users have their sights set on primary storage deduplication and compression. As data continues to grow, many IT organizations can't afford to not try any possible solutions to reduce the amount of data they have on their storage systems. This tutorial takes a closer look at the companies that have primary storage deduplication products, as well as those that don't. It also examines three IT organizations that have implemented NetApp's primary dedupe technology and includes a podcast with INI Group founder Tony Asaro on the pros and cons of primary storage reduction. Read the full tutorial on primary storage deduplication in the industry today.
In this tip, find out what primary storage deduplication is, what type of data is suitable for it, the different types of data deduplication, criteria to follow for selecting data for dedupe on primary storage, and the pros and cons of inline vs. post-processing deduplication.

If done correctly, deduplication and compression on primary storage can significantly help to reduce the amount of unstructured data in a system. In this Q&A, Dave Russel, research vice president at Gartner Inc., points out some helpful techniques for primary storage deduplication and compression. He explains the most common approaches for data reduction on primary storage, such as file-level and sub-file deduplication. He also goes into the pros and cons of deduplication vs. compression, how effective they are, and if there are any new developments in the works for the near future. Listen to the full Q&A on data reduction for primary storage.
