Back up utility for windows xp home

I got a new emachine and it had windows xp home installed in.It does not have the back up utility installed.All the infromation I find says that it can be installed for the CD,but all that came with it are thr recovery disks.I get no help from Microsoft at all.Is their a place to download this file with out the having the disk? Thanks for any help you can give.
