1. Plug in an external hard drive twice as big as your internal.
2. Answer "Yes" when is asks if you want to backup there.
The initial backup will take quite a while.
After that, it does incrementals.

It is also wise to purchase an additional drive, identical is size to your exisiting drive, & put that in a powered external drive. Use this drive to "Clone" your existing drive. You can use Disk Utility to do this, but it doesn't do incremental changes to your Clone. Carbon Copy Cloner will do so, but it is paid software. It will also Clone the recovery partition...important that this be done.
Maintaing two backups...Time Machine & a bootable Clone will insure you will never lose any data & should anything happen, you'll be back in business in minutes.
