Basically, all you need is rsync -av. It can work just within your
local computer or across your network. For example, this is the command
that it is embedded in a script that automatically grabs a copy of what
is on my server:-
rsync -av --delete --bwlimit=20000 root at server:/home/
but all you need for your purposes as a beginner is probably something
sudo rsync -av --delete /home/ /media/YourBackupDevice/
using sudo so that you can access home directories other than your own.
I think that should work. To get the networked example to work I use a
trick with something called ssh keys. As a beginner don't worry about
that for now, just be aware that there is something you can use to get
access to the content of other computers.
If you're worried, set up a test directory to play with, and experiment
with leaving out --delete and keeping it in, but rsync will not alter
the source directory.
