FTP, File Transfer Protocol, is probably the most widely used way to transfer objects between computers. It should come as no surprise to you that FTP has been available since the AS400 era.
I work in an environment with 11 IBM i partitions and servers, and I can spend a lot of time moving objects between. To move objects between partitions on the same server I use the SAVRSTOBJ and SAVRSTLIB commands. To move objects from one server to another, especially if they are in different geographical locations, I use FTP.
Why FTP rather than SNDNETF or SAVRSTOBJ? In my experience when moving very large amounts of data between servers it can be several hours quicker to FTP the file rather than use the other methods.
This post is going to first of several posts explaining how to FTP a file or files from one IBM i server to another. This method is not secure and I only do this within my company's network or while part of a VPN. I do not recommend doing this in an unsecure environment, i.e. over the internet while not being part of a VPN, as it can be "sniffed" and the data compromised. If you do want to send data via an unsecure environment then use SFTP, Secure FTP.
