FTP Backups, FTP Virtual Services, and High Availability (HA): If using automated backups through FTP in a HA environment, adding an FTP Virtual Service causes the FTP control connection to be initiated from the administrative IP address, while the data connection is initiated from the shared IP address. You must configure the target FTP server in ‘promiscuous mode’ (as is best practice for an FTP Virtual Service) to mitigate an 'IP Security' failure returned by some FTP servers. [Note that this is not an issue for SFTP.]
