Just to expand on Krale's tip, I did something similar to that a couple years ago on a server that I'm admining (too many users that don't know what they are doing, and too many typo's). Since the backup directories were filling up too fast, and using too much valuable disk space, I extended my scripts to update a small database and keep track of which garbage folders had files added to the recently, and then had a daily script that would simply delete anything that had been in the trash for more than 2 buisness days. I find that gives the users enough time to realize they deleted that report that the absolutly need,but keeps enough disk space that I don't have to keep shuffling data around.
