Ok I have been watching it for a few weeks. Kloxo makes the backup. It then makes the ftp connection. Looks like its logging in trying to make the upload dir which fails, then changes to the dir, and then exits.
Dont matter if it is a scheduled or manual backup. Both does the same.
here is my ftp log (I changed the ip & username)

Right now I am getting around it by doing a weekly backup on sunday, and then monday night using rsync to sync the backup dir to the kloxo backup dir .
