Thank you fireworker. I was able to confirm that files and folders whose names begin with a period/dot are saved to the pVHD container archive, and can be recovered by mounting the archive and copying from that mounted disk image. I successfully recovered what I needed. So it's not a major problem that I encountered (i.e. things not getting backed up), but is just a bug in the Restore Wizard which can't handle such names. Thanks again.
