The Windows port is still in Beta, it's true,
Though your ZFS data should safely pull through.
But crashes might happen, bugs may arise,
From upstream or here—there could be surprise.
So, start with some test data, give it a try,
Build up your trust before reaching the sky.
If issues appear, don’t let them persist,
Just file a report on GitHub’s bug list!
Ugyanaz a fejlesztő csinálja, mint a MacOS portot, azzal nem volt gondom, de nem is mission critical felhasználása volt.
