I don't have much to backup so i don't need a lot of space.
I assume i need an external drive to do this.
I would like to use Time Machine but the Drives are quite expensive.
I use a couple of different backup strategies.
I have a 4TB external hard drive that I use for Time Machine.
I have a 1TB external hard drive that I use with Carbon Copy Cloner.
You can use any USB 2 or USB 3 external hard drive for backing up with Time Machine, you don't need to use a Time Capsule with Time Machine.

In order to do proper backups you should have a minimum of 2 backup schemes. The reason being is backups fail, don't laugh or scoff they do all the time. You should have 2 external HD's for backing up. A popular plan is to have:
Disk 1 as a Time Machine backup.
Disk 2 as a bootable clone using either SuperDuper or Carbon Copy Cloner.
Both apps work differently. TM will create a master backup of your whole system and then create backups of changed files every hour. This is extremely useful if you lose a file, setting, app etc but know you had it at an earlier time.
A bootable clone creates a master backup of your system and can update changes however it won't keep old files. The advantage of a cloned system is if your internal HD crashes you can boot from the clone and continue work.
NEVER EVER store 2 backups (TM and clone) on the same internal HD. The rational is HD's fail every day and if you keep both schemes on the same HD and that disk crashes you'd screwed yourself.
I do the same except I also use Crash Plan cloud backup in case of theft or the house is distorted.
3-2-1 backup strategy.
3 copies, 2 different media, 1 offsite.
I use Time Machine to a Time Capsule, Time Machine to a Thunderbolt disk, and Backblaze.com.

I think you may be confusing Time Machine (the OS X backup software) with Apple's Time Capsule hardware router and hard drive combo?
You can just use any USB external drive with the included OS X Time Machine software. This drive by WD is pretty popular and you can get a 1TB for $69 USD.
Just received the drive you suggested. What should I do before plugging this in?
