desktop~ ?

[Thomas L Roche]

Has anyone got a way to make 'desktop' back up its most-recently-used
file? Why I ask:

I recently whacked my desktop file when emacs (GNU Emacs 21.1.1
i386-msvc-nt5.0.2195) of 2001-10-22 on buffy) abended. Fortunately, at
my main workstation, all my emacs stuff gets backed up nightly, so I
just restored. Unfortunately I don't have such luxury everywhere I
run. So I'd like to make desktop back up its MRU file, e.g. to
desktop~ in the "normal emacsian manner."

I notice that *Customize Group: Desktop* has a Desktop Save Hook:
anyone got code for that? Or an advice?

Apologies if this is a FAQ, but I didn't see anything in the info.
