copy a local file back to local drive Backup

Hi, I have to update files on a daily bases on my local system then only copy/move the latest version to the remote drive. What is the easiest way to do this? Now, I "copy" upload the local file to the remote server, rename it on the server, then "move" it back to my local drive. There is got to be a better way. I tried writing a custom command could not get that to work.
