Is there a practical way to do this:
- Clone SSD A to SSD B of the same size.
- Boot from SSD B, but retain SSD A in the system.
- Set up scheduled incremental backup so that periodically SSD A should be made identical to SSD B. (Not sure if this should be done on a file level, or other—open to suggestions.)
- In case of SSD B failure, plug in SSD A as boot.
(Incremental backup is preferred to simply reduce backup times.)
