As already suggested by Chris userid+ip based backup file should be
ok.

A message has to be displayed but this won't be enough if the user
cannot compare his backup file with the current file, as the file
could have changed since the user lost his edit session. By the way
when is this message going to be displayed? when the user edits the
page again? when he views the page? Both?

Whole is more logical in the backup context, i.e. we take out the
whole backed up file. Editing only the section could let the user
think that the rest of the doc was lost.

4a means that if user A crashes his session leaving a backup file
and if user B changes the file before A comes back to edit/view it
then the backup will get removed. Do we want that?
4b/c, considering that this backup feature is an answer to browser
crashes, network outages, power failures, or anything that can
happend to an editing session when coffee gets spread all over the
keyboard, I don't think these backup files are meant to replace a
revision system, so they should have a limited time to live of a few
days.
