Snapshot & Replication: backup pool on the Remote ZFS Volume/Dataset is empty (total loss of data).

This is the bug I've just posted

https://bugs.freenas.org/issues/5293

I'm crying

I installed FreeNAS v. 9.2.1.6 from scratch (not upgrading from older versions).
I have two pools ("storage" and "backup") which were created with FreeNAS v. 9.2.1.3; I exported them before proceeding to the new installation.
The new install went ok; then I setup a Periodic Snapshot Task and a ZFS replication task.
This very first snapshot & Replication task was due to run at 05:30PM.
Replication (from the "storage" pool to the "backup" pool) was successful, ending at 08:30PM.
I compared bit-by-bit the files from the main dataset with the backup dataset (with diff -qr <dataset1> <dataset2>). ALL WAS OK.
At 00:30AM another Snapshot & Replication was due to run.
Snapshot at 00:30 ran correctly; the Replication task Status says "Succeeded".
Checking the Remote ZFS Volume (= the backup Volume) tells me an horror story: the Volume is EMPTY!
Which logs do I have to post?

I would definitely handle this in that bug ticket. The devs may ask for remote access to your server. Strangely, I setup 2 VMs with 9.2.1.6-RC last night and I had no problems with test data. :/
