To close this out, we have a workaround for the problem that DaveMc
reported. This is a known bug that we are trying to get fixed for SP1. The
workaround is:

1. Click Start, click Run, type sdclt.exe, and then click Enter. (If Run is
not on your Start menu, you can type “Run” in the Search box to find it.)
2. Click the Backup Files button on the left.
3. On the right side, click the Change Backup Settings button.
4. Go through the wizard, keeping all settings the way they are until you
reach the last page.
5. On the last page, check the checkbox named Create a new full backup now
in addition to saving settings.
