Description:
When performing incremental backup, do not specify a value for --start-lsn option. 
This will result in an error but wrong message as

Error: Missing or invalid option :
   Missing --incremental-backup-dir option. Specified Operation: backup

How to repeat:
Run incremental mysqlbackup,
--exec $MYSQLBACKUP --port=13000 --protocol=tcp --user=root --incremental --start-lsn --incremental-backup-dir=$BACKUP2 backup > $LOGDIR/backup-inc1.log 2>&1

The above command results in an error as 

Error: Missing or invalid option :
Missing --incremental-backup-dir option. Specified Operation: backup

If you notice it mentions about missing --incremental-backup-dir option which is not the case. Instead the error occurs because of missing --start-lsn option. 

The message needs to be corrected to be more intuitive.

Suggested fix:
The message needs to be corrected to be more intuitive.

The wrong error occurs even if no --incremental option is specified when performing incremental backup. The error shows as "Missing backup-dir option instead of missing --incremental command.

The backup log shows following error,
Error: Missing or invalid option :
   Missing --backup-dir option. Specified Operation: backup
