The scenario I have in mind is, a poorly maintained server, nothing
installed, can't install anything (no internet connection, license
expired), flaky network, you fear it's going to fail soon, you need to
take a backup.  The simplest procedure would appear to be: start backup
mode, copy files away, stop backup mode.  Anything else that involves
holding a session open over there for the whole time is way more fragile
unless proper preparations have been made (and even then).  So I don't
know what you want to call that scenario, but I would feel more
comfortable having these basic tools available in a bind.
