Being a total noob and still in the process of learning, i would like you to explain something i read about ZFS
"FreeNAS ZFS
ZFS, for all it’s sheer awesomeness isn’t perfect. For starters (and this is a FreeNAS thing), only the more recent versions of ZFS have data deduplication. What’s data de-duplication? Well, Windows Home Server has a feature where if you have 2 copies of the exact same file, it’ll only physically store one of them to save space. ZFS goes beyond that, and in addition to that, if you have *parts* of a file that are the same, it’ll only physically store one copy of those parts. All automatically in the background (assuming it’s turned on of course). FreeNAS from what I gather will eventually get this, but it could be a while yet, while other NAS’s like Nexenta and EON already have it."
So basically if i have two folders each having the exact same content, lets say 30.000 files and using 25gb, zfs will do the miracle of using only 25gb of space instead of 50gb and 30.000 physical files on the drive instead of 60.000?
That sounds too good to be true. Please enlighten me :)
