Please clarify what you're asking about. Since SP3 is always on the Windows Update servers, there's generally no need to make a backup of it.

Are you, perhaps, asking how to put XP SP3 on to a CD/DVD, so you can take it to a computer without internet access?

In any case, you can download the standalone XP SP3 update file here.

Yes, it says "for IT professionals", but ignore that. That's the right file.
