Why do you want reinvent the wheel?

There is enough software - also for free - which does what you want.

Why not using them?

Note, instead of backup software you might consider a versioning and configuration tool. SourceSafe is for free with Visual C++ pro but you also may use a free tool like cvs or reflection. Contrary to backup systems, versioning tools generally store deltas. They automatically create a full file version if the deltas were too many or need more space than the original file.

I have seen a few Windows implementations of versioning systems based on pure RCS. I will make some investigations for free RCS libraries for Windows.
