Tom, forgive my ignorance but would the “bunker” be/could be stored in ZFS pool managed under truenas?

Also, for rule of 3, if the bunker was a ZFS pool would you just copy that entire truenas to another location but with less frequency?

The reason why I ask is the idea in my head would be to have a Tailscale network to combine everything to manage. With two offices one with the “main pool”, the second office with the NAS, and a home office as the 3rd back up. Don’t know if that is a crazy idea.

3

If you use ZFS replication between sites the VM UUID for the storage would not match. But ZFS replication between sites is a good idea for all the other data.

4

Understood. Is there anyway to get to a “rule of 3” with the VMs? Or maybe point to two different destinations at the same time?

5

Yes, you can send the VM’s to more than one destination, but what makes more sense to have the off site backups as shown in the diagram.
