I have a FreeNAS 11.2 box. I'd like to use zfs send to send snapshots to another box.
Can that receiving box be a Linux machine or does it need to be FreeBSD?
What if the FS is encrypted using FreeNAS's GELI scheme?

Yes, you can definitely send ZFS snapshots and filesystem streams to other ZFS-based systems. There's nothing that would prevent this.
As for the usability of the encrypted filesystem on the target (receiving) server, I don't think that will work.
You're welcome to try this. Is there any reason you haven't tested yet?

1The encryption won't matter. GELI just encrypts the data blocks stored on the disk. Once you're running the OS live from the encrypted filesystem, the snapshot is just a snapshot. I second your encouragement that the OP test. – Jim L. May 3 '19 at 0:12

Testing likely means building another box. That means buying hardware. I asked this question because it will inform the type of hardware I'd buy. – Adam May 3 '19 at 1:00
