Read the following.
Mac 101: Time Machine
You can use time machine to do automatic backups, or you can back up when you choose.
Time machine will create multiple backups on the external HD, and when the HD is full, it will delete the oldest backups.
When you restore from time machine, unless you specify to restore from one of the older backups (from time to time you may find reason to do this), it will restore your system exactly how it was when you backed it up.
Bootable clones, are complete duplicates of your system, so if you have problems with your internal HD, that you can boot from the external HD.
