I don't put the images (clonezilla or VM files) into backuppc at all.
The copies just work as they usually do.  And once they are running,
you just have the same process you would have if someone deleted
something accidentally to bring the files back from backuppc.

I don't do an overlay restore.  Just smb or rsync.

The (possibly outdated, but complete) VM image or clonezilla backup
will boot.   The windows systems I back up are either single-purpose
application servers where I know how to reinstall that app if needed,
or generic file servers where there isn't much windows magic.   There
are more complex windows servers in the company where it might be
important to track frequent registry changes and program updates, but
someone else manages them, probably with proprietary programs.  If I
had to do those, I'd probably at least use the volume shadow copy
tools during the backup.
