Restoring ignition backup

I am using version 8.1.1 on two machines. I did work on one and made a gateway backup of it. I then restored the backup on the other machine. While most seems to be there I am missing all of my devices on the backup that was restored? What could cause that to happen? I am worried that more things may not have been transferred over as well now.

Make sure you’ve installed all the same modules. Modules aren’t included in a gateway backup.

Ah, didn’t think about that. thanks!
