We won't be able to tell you that. You will have to determine what is most important to your organization to backup. For simplicity, definitely backup the DB. If you wanted to backup anything, I'd probably suggest the secondary storage, as it contains the templates, isos, and snapshots; of which you'll likely be able to recover from (rebuild instances) more easily.
