Someone along the way in your computer experience must have told you to Backup your computer or risk losing all your precious pictures, videos and documents. Many programs have been created to help you backup your computer. Most of them cost money. This is where Automator comes to the rescue!
If you haven’t started using Automator yet, this is a good place to begin. I will first need to download a plugin for Automator called BackUp Folder to make this work.
Download Backup Folder from the Automator Actions website.
http://www.apple.com/downloads/macosx/automator/backupfolder.html
Unzip Backup Folder.zip
Drag Backup Folder.action to the MacintoshHD:Library:Automator folder.
Open Automator.app in your Applications Folder.

You’ll notice Automator is split into three sections. The Library / Actions Palette is positioned on the left. Your workflow is on the right. A small text box rests on the bottom left that explains what each action does. A run button is on the top right and search bar is on the top left. You can search for actions here, instead of browsing through the Library.
Many different applications can be used with Automator. These applications are called “scriptable”. For our purposes of backing up data, we are concerned with the Finder. So, in the Library listing, Select Finder. You’ll notice the Actions now have changed to Finder specific actions. Each action has a rating bar to the right of it. These rating bars indicate the level of relevance a particular action has in the next position of your workflow. Because we haven’t placed anything into our workflow yet, Automator thinks a lot of these actions are a good place to start. Drag the action called Get Specified Finder Items to the workflow.
Soon we will add the Backup Folder action. But first, we need to understand what the Backup Folder action needs to work. Backup Folder needs two folders input into it. The first folder we specify will be the folder you wish to backup. I wanted to backup my Pictures Folder to my External Hard Drive. Click the Plus Sign in the Get Specified Finder Items Action and Select a Folder you want to backup.

Your window should now look like the one above.
Open the Finder
Make a New Folder in the place you want to backup the first folder. Name the new folder something relevant. I recommend backing up data to another hard drive. In my example, I backup the Pictures Folder to my External Hard Drive called Candy.
Return to Automator.

Click the Plus Sign in the Get Specified Finder Items Action and Select the Folder you just created (the folder you wish to backup to).
Search for Backup in the search bar.
Click and drag Backup Folder to your workflow, under the Get Specified Finder Items action.

Do you see how Automator chained these two actions together? Now you have a workflow! These two actions are all we need to backup a folder.
Now you are ready to save your workflow. If you select File -> Save you will merely just save your project file in Automator. We want to integrate this workflow in how we do things in OS X. Select Save as Plug-in in the menu bar.

I named my plug-in “Backup My Mac” but you can name it whatever you like. Select iCal Alarm from the drop down menu. Click Save.

iCal Automatically opens. The greatest part about backing up data is you can set it up and forget about it. Drag the iCal entry to a downtime where you will not be using the computer. On the right, Select Repeat and set it to the interval you wish to conduct your backups.
Return to Automator.
Click Save in the File Menu. Name your Backup Project and save it.
There you go! You just created your first backup using Automator!
Want to backup more than one folder at a time? That’s a piece of cake! Just go back into your Project File in Automator and chain together another set of Get Specified Finder Items and Backup Folder underneath the first set and so on.

Notice how Action #3, the Get Specified Finder Items Action is not linked to the first set of actions? Make sure you Click the Files/Folders on the top of each Get Specified Finder Action and Select Ignore Results From Previous Action. If you don’t, an error will pop up when you run the workflow.
