It seems to be quite normal for the user base of Cpanel to use unencrypted FTP. It that because encryption is not need for you FTP server since they are all in the same DC and everybody inside the DC is trusted?
Since the backupfiles are not encrypted the data can be sniffed.
I posted a feature request 10 months ago to see if others are searching for that, but no one seems to search for it.
