Storage for Jira products and Confluence is primarily made up of attachments. Each Jira and Confluence plan comes with its own storage space. If you have more than one instance of a product (e.g. two Confluence instances from two sites), each include their own set of storage.
If you're an admin for one site, you'll land on the Users page of your site.
If you're an admin for multiple sites or an organization admin, click a site's name and URL to open the Administration for that site.
Choose Storage in the left panel. For each product, you’ll see the amount of storage used and the amount remaining (if it’s not unlimited).
What happens if I exceed my storage limit?
Storage limits are not currently enforced. If your Confluence or Jira products exceed their plans' storage limit, we won’t cancel your subscriptions or remove any data, as long as usage is in accordance with ouracceptable use policy.
Keep in mind we're planning to enforce storage limits soon. We’ll let you know ahead of time in case you want to upgrade.
Can I increase my storage limit?
Each Jira and Confluence plan comes with a set amount of storage. Currently, the only way to increase your storage is to upgrade your plan.
