Look up "InterimFiles" in undoc.txt This is a highly convenient method of getting backups. It's also easy enough to have a scheduled daily job move these checkpoint files to an archive directory & throw away the oldest ones just leaving the last N. Well it's trivial on a linux system, I guess it's easy enough on a windoze system - especially if you already have a task scheduler running (e.g. because you installed Norton Antivirus).
