I'm unable to get "Upload to remote FTP server" post processing option to work.
I tested this with 2 versions of Akeeba: 3.0 Pro release and svn174.
Test was run to two different hosts.
Two different FTP servers on two different hosts were tried. (Not on the Joomla hosts)
All test were tried with and without passive FTP option
In all cases the FTP connection test in the configuration page tested OK
Archive file size was 24KB - both zip and JPA were tried.
No files at all were transferred - not even a 0 size file.
Interesting to note that DirectFTP option (without post processing configured) also failed. This without an error message.
I have uploaded 2 log files. Log Files
