Replication to separate pool

TrueNAS General

I am trying to replicate one dataset too another pool.

I am using the wizard and setting up a new snapshot and the replication task keep failing.

This is the error that is showing up.

This is how I have my replication set up. What am I doing wrong?

Ummm.

Is there any history behind this error that we need to know?

Not that I know of.

I am just trying to backup my host path app data folders to another drive.

I followed lawrence systems for how to set up a replication task which would also create a snapshot task. I just dont know why it isnt working.

I have encounter similar situation.
Probably there Is a better way, but
I solved deleting everything related to the job (destination dataset, replication task, ecc), recreating the task adding the flag on full filesystem replication, then Is working as expected

I solved mine by setting up snapshot tasks following stux’s guide. That worked for replicating from one pool to another.

To replicate from one system to another I had to set the full filesystem flag as well. And had to create another snapshot to get that going.
