Bootable external USB

I have a problem, probably user created. I am running a Macbook Air M1 with Monterey 12.1. I backup weekly alternately to MacbookProOdd and MacbookProEven with SD 3.5. MacbookProEven contains backup of system 11.6.2 and MacbooProEven is last nights backup 12.1. External is USB 3.0.

I've searched and get mixed comments as to whether or not a USB 3.0 drive can be made bootable in this environment. I wanted to archive my 11.6.2 backup and tried going from external to external. I thought I could do this, but told no. Next I tried booting to this backup and was successful, but it was so slow, I gave up. Now I can't boot from either 11.6.2 or last nights 12.1 backup. Both get about a third of the way through the boot progress bar and then reboot to the system drive. I tried setting the 11.6.2 disk to my startup disk and got the attached message.

Probably need better backup media?

So, the 11.6.2 message is normal and you'd want to authorize a user - it's from a different Mac, and this is basically security stuff. Authorizing should work.

With regard to slow - that's likely the media. Is it an HDD or an SSD? USB3 is fine...so that's not the issue.

It's HDD. I Have been using for many years with my Intel Macbook Pro. WD 2 TB partitioned into 2 - 1TBs. Never a problem booting either. Both should be bootable on M1. Correct?

If the Mac itself can run the OS, it should be able to boot from the copy of it.

I would *strongly* suggest getting an external SSD. 1TB is about $120 right now (https://amzn.to/3sRekjy - affiliate link, so I'd get a teeny tiny kickback, but that's not why I suggest it) and 2TB is $199 (https://amzn.to/3EMHToJ).

I appreciate the recommendation. I was going to ask.

I have something flakey going on. I just did an erase copy, booted to the drive, no problem. I then did a smart update copy which is my normal MO. Now the drive won't boot. Prior to the erase copy, both my drives were smart updates, albeit one Big Sur the other Monterey. Neither would boot.

Smart Update just updates the data volume. It doesn't touch the OS... what happens when you try to boot?
