I have a error notify while uploading larger/longer duration ftp files.
I have passive mode on and files like 30GB are transferred without problems, only when transfer takes more time than ex. 1h11m (>4260s) then the error 'An I/O exception occurred" appears. I tested more data (~35GB), tranfserred 1h21m then error appears.
BUT despite this error all files are copied to the ftp server and are the same with local copies!
I have used Cobian Backup before without problems with FTP.
LOG debug in Cobian Reflector:
