... my snapshots to another place



how can I save automatically all snapshots to another SSD in my system?



have you read the TrueOS handbook? i think there are instructions in there


ZFS snapshots by definition stay on the same ZFS pool as the data when you take them.
If you want to replicate those snapshots to some (remote) ZFS pool for backup purposes, then I would recommend setting up the “Life Preserver” utility that TrueOS provides out-of-box.


And if the original poster wants more background and details, and likes to do it more manually, he/she could look here:
