For the purpose of setting up an automatic backup solution, we will use one of the coolest Backpack's options - unique e-mail address. Every page you generate has its own private e-mail address. This means that sending an e-mail with different files to this address will be the equivalent of using the web forms to manually upload them.

First you need to login into your Backpack account and create a new page.

Upon creating the page, do check its footer and you will see an e-mail address.

Now, we have generated the page and snatched the page's e-mail address. Go to the Applications folder and open Automator. Our backup application will have four actions and you will use a specific folder that will hold the files you want backed-up. After starting the application, the files from this folder will be e-mailed to the specific Backpack page and therefore they will appear online.

1) Finder -> Get Specified Finder Items

This action passes the specified Finder items into the next step of our application. Here, we will setup a folder that will host your files. The output of this action is the location of the backup folder.

2) Finder -> Get Folder Contents

This action gets the items from inside the specified folder and outputs them to the next action.

3) Mail -> New Mail Message

Here we will setup the needed e-mail message fields, as well as the account that will be used for sending. The previous action will automatically feed the files from the backup folder as attachments to this new message.

4) Mail -> Send Outgoing Messages

This is the final action we will need. It just sends our e-mail, so we don't have to do it manually.

The last step is to save our workflow as a new application.

Now you just need to start the application and your files will soon appear in your Backpack account.

I should just mention some specific things you should think about:

- If you are backing up personal files, do check out if you shared the page with someone or made it accessible by anyone.
- As the backup process is utilizing your e-mail, do watch out the size of files you are backing up. Some e-mail accounts have a maximum of 10 MB per message. Also check the amount of free space you have on your Backpack account.
- Backpack will automatically sort your files in their respective categories such as "images", "files" and "e-mails". Under e-mails you will find all *.txt files that were backed up in the process.
