Windows has a nice option to its XCOPY command: /D. This copies only files where the source modification time is newer than the destination time. Is there any unix/linux equivalent of this? I'm trying to get a fast copy to my local testing server.
My brain couldn't quite cope with the complexities of rsync so I installed Lucky Backup. This provides an easy to use graphical interface as a front end for rsync. When you've set up your copy/backup task, you can run it from the programme. You can also click on the "validate" button for the task and it will give you the full rsync command line such that you can run it in a terminal or paste it into a shell script. It's a nice tool for teaching the use of rsync.
Clicking on the "Advanced" button in the "Task Properties" window gives access to some of rsync's features.
