I've using robocopy to copy a 300GB files from one Windows Server to another Windows server over the WAN. However, I keep getting errors after copied several GBs and retrying from start. (for example, Error 317).
Are there any tools/scripts (prefer the built-in ones or "green" executables) which can resume copying if error occurs? I don't have physical access to the servers so sneakernet is not an option.
"best way to transfer huge files across network"
is simply asking for opinions as "best" is highly subjective and varies across environments/needs.
