You didn't state which version of Excel. In 2010, go to:

1. File tab > Options; the Options window opens.
2. In the left navigation pane click on Save.
3. In the right content pane, check Save AutoRecover information every.
4. In the spin box select the time interval in minutes.
5. Check Keep the last autosaved version if I close without saving (this is a precaution step only).
6. Set the file location path (or accept the default).
7. Click OK.
