Cannot detect ZFS disk Time Machine backup on restore

[SuperShinyEyes]

Hi,

I'm testing my own ZFS time machine backup on my Ubuntu.
Here's a setup:

• Ubuntu 16.04
• ZFS: Loaded module v0.6.5.11-1ubuntu3, ZFS pool version 5000, ZFS filesystem version 5
• netatalk 2.1

The backup works fine and I can browse the backups.
The problem is when I try to restore on Firmware, the Mac cannot detect the backup.
I don't think it is a netatalk issue because I can restore the backups that is on ext4.
On Firmware I tried to mount the backup disk with

afp://username@ip/shared_dir     # shared_dir is the lowest directory of the path

without any success.
Have you tried full restore? Did it work?
