Auto back up save

[velayudham]

[FONT=&quot]Is it possible to save a file to multiple locations EVERY time someone amends it? At my office we share docs and 6 people can edit the same doc. I want to be able to create a backup of the file to a diff folder every time someone makes a change and saves it. It has to be a diff folder because the file is too big to put a backup in the same location. Can someone help please? Thanks[/FONT]
