After I did a full backup of my data set and later wanted to compress this data set, backup didnt provide a way to do this.
When I ran --compress option I get this error

ibbackup: Error: cannot create /usr/local/backup/ibbackup_logfile. Check that the file does not exist yet.
ibbackup: Run 'ibbackup --help' for help.

So I manually deleted ibbackup_logfile in order to have a compressed backup.
Is this a limitation or is there something I am missing?

Thank you for the report.

Please send exact command line you used when created backup first (not compressed) and second (compressed) time.

Thank you for the feedback.

This is not a bug. Please double-check the documentation available at http://dev.mysql.com/doc/ and the instructions on how to report a bug at http://bugs.mysql.com/how-to-report.php

ibbackup --help says about compress: "--compress instructs the program to compress the backup copies of data files." But it does not say it will compress existing backup. It will compress backup taken in time when ibbackup is called. Thus it does not work with existent backup.
