I didn't contradict myself at all virtually nobody needs dedup its not remotely worth the RAM cost for 99.9% of users.
Can you quantify what you are saying. What OS/filesystem? What minimum RAM requirements for what amount of storage?
- lazide 5y agoThat’s a good point - I’ve seen free memory drop every time I’ve built the larger file systems (and not from just the cache), but I never tried to quantify it. And I don’t see any good stats or notes on it. seems like no one is building these larger systems on boxes small enough for it to matter, or at least google isn’t finding it.
- michaelmrose 5y agoAnother way of saying this is that RAM usage doesn't meaningfully scale with storage size in scope of storage systems encountered by actual non theoretical people because the minimum ram available on any system one encounters is sufficient to service the amount of storage that it is possible to use on said system.
- AdrianB1 5y agoThe main case of deduplication that I know is hosting many virtual machines with the same OS. If that OS is Windows (explains why VM and not containers), there are dozens of GB of data that is duplicated per VM. It is not 'nobody', even if it is not common and not always worth.
