Hello, The methods I know,
1. scp pros: the native tool in the OS cons: you will either input password or put key pairs into servers for authentication. 2. rsync pros: it can transfer data by increasement cons: you need to setup rsyncd server and make the correct authorization. 3. ftp/ftps pros: easy to use cons: need to setup ftpd server, and the way is not that secure? 4. rclone pros:easy to use cons: hard to setup (you may need a cloud storage for middleware). For me I most often use scp + rsync. and what's your choice? Regards, Ken
