If you have a need to do a simple file backup where you need to keep a certain number of historical backups, a simple utility to take a look at is Gammadyne’s Backup9.

The BACKUP9.EXE utility will maintain a number of backups (9 by default) of a file. [For example] foo.bar.bk1 is the most recent backup, foo.bar.bk2 is the next most recent backup, et cetra.

This utility is ideal for a simple “rotating” backup system where the oldest backups are automatically purged. If you were to use this utility in combination with my backup script (tooting my own horn) doing a full backup each time, you can have a completely automated backup system where as much history as you need can be kept.
