Vista backup disks and files are not usable in XP. Microsoft from what I can tell is not releasing a tool to read or restore from their new backup program (in XP.)

To work around this, be sure to backup the old fashioned way. Such as recording the files you want to closed session CD or DVD media or even copying to an external drive using nothing more than Explorer to copy the files.

If you feel this is not a good answer, please call Microsoft. They need to not slam the door on XP so fast.
