Hope you find it helpful.
He tells you how to set up a crontab to launch rsync automatically if you want. But, if you want to, you could put the rsync command directly into a Desktop Config File (shortcut) to run it manually and easily without typing anything. Alternatively, you could put the rsync command into a shell script in, say, your home directory and use a Desktop Config File on your Desktop to run the shell script. If you want to see an example of setting up a Desktop Config File to run a shell script, have a look at my post in the following thread: viewtopic.php?f=52&t=10519
If you just want to run one rsync command, just type the rsync command directly into the Command box under the Application tab of the Desktop Config File. That's how I did it to start with, but I changed later to using the Desktop Config File to run a shell script so that I could put several rsync commands in the same shell script and also automatically create a file recording the date and time when I made the backup. I have two Desktop Config Files on my Desktop with nice icons: "Backup_1" and "Backup_2" and I use them alternately so that I don't screw up my backup unintentionally. Each shell script creates a text file on my desktop which tells me when they were last run. Of course you can do these things all sorts of different ways, but that was the way I wanted to do it. Have fun.
