I'm confused on this. If you can only run one at a time, how can you
bring the second one up (temporarily), be it for migration, redundancy
(off-line backup?), establishment of a new vm (paid), or any such thing?

I can see this 'backup' as a copy of the current that you beat up on
for, say, an upgrade trial / attempt before making it production, but
other than that, I must be missing something.

[Not specific to linode - backups generally:]

Hold on, are you saying if I 'cp remote:/ local:/' ('sp?'), then put
local:/ in another machine, I have an exact and functioning duplicate?

i.e. No backup issues of in use files, copy /proc, etc. is OK, all is
happy, etc., etc.?

[Surely, even in Linux, 'disk duplication' / pop it in different
hardware, isn't that simple?]
