"cron" is what you use to schedule tasks.
I like "rsync" too, if I only want the most recent copy of something. Otherwise I use "tar" to bundle up multiple files into one, and use the "date" command to name them with option "--date='last week'" to get a date in the past to match the name of the file I'm wanting to remove.
That should be enough rope to shoot yourself in the foot.
