I would like to follow the rules of serverfault, and I think I am good at that, but I am somewhat confused as to why this question was marked as off topic:

https://serverfault.com/questions/458163/does-sftp-server-via-ssh-server-on-linux-support-file-transfer-resume

The only thing I can think of is that perhaps one or more of the mods don't consider SFTP a technology to be used in a professional environment?
