Here are the short instructions on how to backup and sync all your Gmail emails with Dropbox.

Go to cloudHQ.net

Click on “See Plans and Pricing.”

Click on “Get Started” for the Premium Plan.

The sync wizard will appear.

Drag the Basecamp icon to the empty box on the left. Note that if you still use a Basecamp Classic account you will need to drag the Basecamp Classic icon.

Click on “Sign Up with Google Account” and you will be forwarded to the Google page.

Click on “Allow.”

You will then be prompted to sign in with your Google ID.

After the account is created, you need to authorize cloudHQ to access your Basecamp projects.

Click on “Add Basecamp” and you will be forwarded to the 37signals Basecamp page to confirm that cloudHQ can access your Basecamp projects.

Click on “Yes, I'll allow access” and you will be redirected back to cloudHQ.

Click on the arrow to list your Basecamp project. You can sync all of your Basecamp projects or only the projects selected. For now, let’s just click on the top level folder which means that cloudHQ will sync all of your projects.

Tick “Sync only attached files” checkbox if you want to sync only Basecamp attachment and exclude discussions, to-dos and calendar. Let’s select this option.

Click on “Select” to confirm your selection.

In this step, just drag the Google Drive icon into the empty box on the right.

So click on “Add Google Drive” and you will be forwarded to the Google page to confirm that cloudHQ can access your Google Drive files. Click on “Authorize” and you will be redirected back to cloudHQ.

Name this folder something like “Basecamp Projects in Google Drive”

Click on “Create Folder” to create a new folder.

Click the newly created folder and press select.

Now you need to select the sync options. For example, you can decide whether to sync only archived projects, active projects, or both. For now, let’s configure this sync pair to sync both archived and active projects.

And finally, just click on “Synchronize Continuously” and we will start an automatic and continuous sync of all your Basecamp projects with Google Drive.
