Your function does not seem to work in this sense, hiding files in a
big and vast tree.

you can easily write a restore-backup function in emacs (possibly
bundled as default) that retores the file from emacs's backup. This
way, the emacs backup system is completely transparent. When a user
needs to retore from backup, she can just Alt-x restore-from-backup.
(either on current buffer or prompt for file name...)

for programers who likes to manually see and get the backup file for
whatever reasons, she can do so easily, since the dir path info is
kept intact.

PS addendum to my previous suggestion about sperater dir for emacs
backup: the default backup dir should be fixed by default such as
".emacs_backup". (as opposed to asking a user to set it.) User can
still change it of course. The thing here is that having a
standardized emacs backup dir location is good.
