to clone the whole system you should not forget hardlinks (-H), and may be
also ACL (-A) or extended attributes (-X) should be preserved.
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
When the cloned disk is updated several times, also option -u (=update only
if needed) can be used.
# rsync -avuHAX --delete /mnt/sda2/ /mnt/sdb2
