Deduplication is a cool technique that some admins use when it comes to saving storage space. No wonder. By deduping, you can gain some extra storage even without deleting anything. Everyone seems to use it, but how does that thing, actually, work? In this article, I’ll look under dedupe hood to understand better its operating principles. Why one may need this? You see, you always can make the most of things once you understand how they work. I believe this principle to apply to almost everything! So, here’s why I examine such a common storage optimization technique as deduplication in this article.
