Hi,
backup the .aspx, .aspx.cs and .aspx.designer.cs files. Also take a look in the .aspx page if it uses user controls. If so also backup those.
Usually reusing an entire page is not the way to go. If you have things that can be reused either create a user control or dedicated custom webcontrol for it. That last one is usually the preferred way to be used as building blocks like a grid control or
any other easy to reuse part.
