The only concern I see here is the external drive. My experience has been that powered off drives fail more often than constantly-on drives. So my external drives are always powered on, I just run a replication script to them on a schedule.
But you do have good coverage, so that’s a small risk.





Of you ever feel like you can’t find the right screws or it just doesn’t hold back together well, just Goop the bastard back together.
So much stuff in my life is now Gooped together - I even Gooped some drives into a desktop that lacked enough mount points.
That stuff is magic in a tube.
