How do I increase the amount of space in my account?

When upgrading your account, select the total amount of data that you would like in your account. Do not select the amount of data you want to add to your current plan.

For example, say you currently have a 1 TB plan but you are about to reach your limit. You would like to step up to the 5 TB plan. When upgrading, you should select the 5 TB plan from the drop-down menu.
