P.S. also, the 2008 pics with Linus. I suppose there is no further story to go with those ...
- alecco 16y agoIMHO, with my little work in compression, all that dedup stuff was a bit hyped. And BTW it is older than ZFS, at least Plan 9's network storage had the same feature. But alignment kills looking for matching chunks of data. And "generally best left to the application" sounds like a cop-out.
- ww520 16y agoIt's the ease of usage, speed, and very large compression window that makes dedup better than traditional compression.
