Can't get Time Machine to work with Nighthawk
Mac OS Mojave 10.14.3
Nighthawk(R) X4S R7800

I bought a new 1TB Seagate SSD external HD. I formatted it according to the instructions low...

I not exactly sure what you're trying to do, and the images are blank for me.
It sounds like you're either trying to have a 2nd Time Machine that backups up a source mac and 1st time machine setup, or have two Time Machines that your mac backs up to and alternates between them. I'm not sure if either of those setups are possible though I'm not really a Time Machine expert, so someone else may be able to comment.
I will tell you that the terminal command, `tmutil setdestination`, only lets Time Machine know it is a valid location for Time Machine to backup (it may set that as the default location as well, I'm not sure as I only have the 1 disk). It won't stop it from backing up to anywhere else.

Based on this page https://ss64.com/osx/tmutil.html , it looks like tmutil may overwrite the current configuration for the new one, but I don't believe that it would mess up the old backups or anything, just point the primary towards the new volume. HOWEVER, reading that page, it may be possible to have multiple destinations using the -a flag.
So something like:
`sudo tmutil setdestination /Volumes/TimeMachine1/` for the first destination and then
`sudo tmutil setdestination -a /Volumes/TimeMachine2/` for your newly created drive.
Again, I have no idea how that works in practice as I've never seen it, but it does look like that is supported in some capacity.
