is there a way to restore deleted files in FreeNAS there are data files I had and I went to move them and now they are gone some how so I wanted to know if there is a way to bring them back
I found testdisk but it is not on FreeNAS is there a way to you that or something else
thank you
Short answer is that it is very challenging and not very likely to get back any deleted files form a ZFS system.
Here is a write up on how ZFS handles deleted files from a company that offers some software (of which I have never used) that claims they can make the attempt.
