rsync doesn't move anything. It copies it. Now you have 2 or 3 COPIES of all that data. Fine if you want a backup, but most of the time, we want backups to be on external storage devices and organized by the backup tool (not rsync).
Code:
sudo rsync -avz /media/data/home/wcalvert/ /home/
I suspect you've just got either the wrong target OR the wrong source. Try
Code:
sudo rsync -avz /media/data/home/wcalvert/ /home/wcalvert/
OR
Code:
sudo rsync -avz /media/data/home/wcalvert /home/
BTW, rsync behaves different when it does copies between two different computers and all inside the same computer. In short, the "z" option says to use compression for the transfers. When the data is all being copies inside 1 computer, asking for compression will was time. And yes, I realize the -avz options are what I posted. please, please, always review every command and learn what each option actually does. It is common for people to type things from memory that don't necessarily fit your situation completely. The local manpage for rsync would be the best place to check options, since it will match the exact version of rsync you have installed. Minor rsync options change all the time, but the major ones haven't changed in 25 yrs, so it isn't terrible to use tools like explainshell.com to have that webpage look at the command with all options and only show the explanation of the relevant options.
Also, if getting everything correct in a terminal makes your brain freak out, there is a simplistic GUI for rsync - grsync. It actually doesnt many anything easier or cleaner, but for some reasons it makes people afraid of CLI commands happier. I'm at a loss for why.
