Word document incremental backing up while the document is being created

On my previous computer with Windows 2000, I was able to make incremental backups of a Microsoft Word document while it was being created by me. The advantage of this was that if an "accident" happened and the document was lost or corrupted before it was completed or saved to a folder, the partially completed document could be retrieved from a special folder somewhere in C-drive. I was able to specify how often a new backup was created (ex.: every 3 minutes, ex.; every 10 minutes, etc.). It is possible that this special folder also contained backups of all previously saved Word documents, which were also being re-backed up every few minutes. -- I cannot find any reference to this on my new computer (Windows XP and Microsoft Word 2002) in the Windows search engine, or in the Word user interface "Help". I cannot remember how I found this feature on my previous (W~2000) computer. -- Thanks

 

I just found where to set up this feature (Word user interface > tools > options > save and also file locations. BUT I STILL NEED HELP BECAUSE THE FEATURE DOES NOT SEEM TO WORK.
