Title: Recovery with a backup file
Post by: tdalej on July 18, 2026, 05:51:14 PM

I'm doing some poking, and I have to identical servers for firewalls -- MAC addresses are different of course.
Last time I did a recovery from one to the other, restoring the backup caused all sort of fun because the MAC addresses don't align.

Is it an accepted practice to edit the backup to alter the MAC addresses first?
Is there a more elegant way to handle the MAC address changes that I'm just missing?

Have a look at this topic : https://forum.opnsense.org/index.php?topic=51075.msg261489#msg261489

Maybe it applies to your situation :)

Sort of.

I'm trying to the recovery with the importer script to see how it gets handled there compared to manual restore.

I can't get the importer to mount the second USB device -- both the boot USB device and the second fat formatted USB device show up as da0 and da1, an it fails to mount with an "invalid device" message.

Got the mount solved.

I have never used the importer script before, always just bulled through manually transferring configurations when needed.
In this case I have two identical Supermicro X10SLH-N6-ST031F (that used to be used for separate locations) that I am going to use one as primary and one as backup.
