Is there an Excel 2003 equivalent to Word's "versions" function?
 

In the file menu of Microsoft Word is the very handy versions function, which
you can set to automatically save a version on closing. THe versions don't
seem to take up any more disk space than when it is turned off. I like it
better than 'track changes' because you don't have to forever be updating the
tracked changes - just use it when ever your missing data that you know you
had a few versions back.
Anyways, if I try to use track changes in Excel, it forces me to 'share' the
workbook which then means I am unable to use macros and hyperlinks. Any
suggestions as to my next best option, gratefully received!
