    ACL Corruption Bug

    I noticed this bug is still open as of 11.1U7 - This prompted me to do a quick check since I am using zfs send/recv to make my backups. Here is what I got from a quick check, and IIUC everything is fine. Am I correct? Does anyone know when/why...

    May I have your opinion on what happened?

    Files copied to server being corrupted?!

    Sorry about the "?!" but that's about how I feel :confused: I've just been testing my FreeNAS install.

    Container File Systems

    Let's say I'm using VeraCrypt on a Windows 10 machine to create encrypted file containers that I'm storing on a FreeNAS server. Those containers would have an NTFS or exFAT file system. Does that defeat the purpose of using ZFS (from a data-protection/reliability standpoint) since I'm basically...
