Over 20 years ago now, I fouled up the backup control statements to
the FDRDSF dump of the development volume so that at least some
libraries weren't backed up.  I discovered it when we went to restore
a development member library.  OOPS.  Obviously I was quick to fix the
problem and make sure I hadn't duplicated it.  Any backup software
will screw up if you tell it to using valid syntax.  FDR backups saved
our bacon on more than one occasion and were the tool for moving the
data when my shop moved data centers so this is not meant as a
criticism of a product I still like better than the IBM equivalent.
