Log Download on sg 230 via ssh

Hello,

my question is still the same as here  Log Download via ssh with the knowledge that winscp with loginuser does not download all Logs (only 2.7 GB of 50 GB) and copying to /tmp is not possible because of the size of  the logged data. I am neither able to watch bigger Protocols on the firewall itself nor can I download them because there is a compression algorithm which is dysfunctionalError Image Firewall Log Download

. The only possibility is downloading day by day, but this will take too long.

Why is loginuser not able to get access to all logs or why is root not able to make a ssh (scp) connection to another machine, it would be easy to copy the log.
