Link: What’s the Difference Between Compression, Deduplication, and Single-Instance Storage?

May 22, 2012 By Stephen Leave a Comment

I recently wrote about compression, deduplication, and single-instance storage over at the IBM Storage Community.

When I talk about the various state-of-the-art capacity optimization solutions that are now appearing in the market, the same comment usually arises: “Isn’t this the same as zip?” Or a long-tenured storage pro will remind me that, “Stacker died out a long time ago, so why is this any different?”

These are good points: The difference between traditional compression and modern data deduplication is somewhat hazy. And it doesn’t help that various implementations fall all along the spectrum from “mildly interesting” to “cutting edge!”

If you can keep your head when all about you are losing theirs…
If you can wait and not be tired by waiting…
If you can think – and not make thoughts your aim…
If you can trust yourself when all men doubt you…
Yours is the Earth and everything that’s in it.
