Startup Idea: Auto Save and Restore Program for Microsoft Documents

Startup idea to develop a tool that automatically saves Microsoft document files every few minutes. This program will run in the background with an on/off feature, holding the saved file until the user confirms it's no longer needed. Additionally, it provides file versioning to 'undo' changes by going back to a previous version. The program is also proposed to have an auto-zip feature to save computer space.

I was at work today and I wish there was a better way to restore microsoft documents after they crash. SOmetime when they crash it is not always repairable or findable. It would be nice if you could use an on/off feature to have a program run in the background that is autosaving a file every 5 minutes and then holding that file in the program until you okay that you don't need ac opy of it. this way, you can prevent deleting of data or you can save multiple versions of a file and "undo" by going back to a previous version. if the program automatically zipped it would save me time and my computer space.
