If you've purchased a premium storage vault, you'll want to make sure that you select it initially when starting each job. You can do this by selecting the "Storage" tab during the job setup (shown below)
Just click the drop-down menu and you can select the 'premium' storage option.
We can also make the premium vault your default storage so you don't have to do this for every job. If you would like to do this, please e-mail firstname.lastname@example.org and we will get this set up for you.
