For data - not programmes - either Freefilesynch or Synchtoy would do what you want. I make a mirror image of all "My Documents" ie Word, photos, music and Outlook on to a second HD and to a USB HD. I prefer Acronis (paid for) for imaging and cloning the System partition - I keep a partition for system, programmes, and another for data. I have W7 Ultimate 64 bit.Google to get links and info. I slightly prefer Freefilesynch but both do a good job.
