Somebody in the thread at some point said:
# This is the rsync bash file for root
rsync -avg /home/ /media/disk/
rsync -avg /etc /media/disk/
You can pile up all the source dirs in a single rsync, the last one is
the destination
rsync -avg \
/home \
/etc \
/other-things \
/media/disk
Yep rsync is great for backup.
