Richard,

A quick glance at the Microsoft ESEBKMSG.H file shows this:

   //
   // MessageId: hrInvalidBackup
   //
   // MessageText:
   //
   //  An incremental backup cannot be performed when circular logging is
enabled.
   //
   #define hrInvalidBackup                  ((HRESULT)0xC800020EL)

Are you running circular logging? If so, you can only perform full and
copy backups.
If you want to run incremental backups, you will need to turn circular
logging off.

Thanks,

Del
