  Bug description: Backup utility db2bak[.pl] copies not just backend
  db files but also changelog db files, which is not associated with
  the backend instance, but the backup code blindly expected it.

  Fix description: If the copying directory is a changelog db dir,
  skip retrieving the backend instance info and just copy the files
  underneath.
