I started a really simple and effective project the last month to be able to fix from bitrot in linux(MacOs/Unix?). It's "almost done" just need more real testing and make the systemd service. I've been pretty busy the last weeks so I've only been able to improve the bitrot performance.

Unfortunatly, btrfs is not stable and zfs needs a "super computer" or at least as much GBs of ECC RAM as you can buy. This solution is designed to any machine and any FS.

Please stop spreading this misinformed statement. I assume you are referring to the ZFS ARC (Adaptive Replacement Cache). It works in much the same way as a regular Linux page cache. It does not take much more memory (if you disable prefetch) and will only use what is available/idle. We use Linux with ZFS on production systems with as low as 1GB memory. We stopped counting the times it has saved the day. :-)

ECC is a nice to have, but ZFS does not have special requirement over say a regular page cache. The only difference is that ZFS will discovery bit-flips instead of just ignoring them as ext4 or xfs would do.

> ECC is nice to have.

Actually it seems ECC is important for ZFS filesystems see:

Interesting.

That's rigth the kind of hardware I was referring to, 1 GB of plain RAM. Truly, I haven't tested ZFS yet for that reason I've always read that ZFS has big requirements so I refrained to try it. It seems I should give it a try. ;)

Btrfs is another story I've used it for years and I'd prefer not to have to use it anymore untill it'll become "stable" and "performance". :)
