Backing up to an external drive

rsync to a ext partition

rsync -av --delete --exclude=.* /home/ /media/Linux/mirror/

• -a : archive mode; equals -rlptgoD
• 
  

rsync to a FAT directory
As they don't support permissions and perhaps some of the linux timestamps, rsync always saves everything with a normal archive save, but this set me on a better direction.
rsync -avrtD --delete --exclude=.* /home/Archive/Music/ /media/FAT/Music
