How to identify storage size in Confluence Cloud using the Space Reports feature

Summary

As a Confluence admin, you can use Space Reports to download a CSV listing all spaces on your site and key details for each space, including Storage used (MB). Use the report to identify storage usage across your site's spaces.

Solution

What is the Space Reports Feature?

Using the Space Reports feature, you can download a CSV file listing all spaces on your site. This CSV includes essential details such as:

Space identity and status (Space Id, Space Key, Space Name, Space Type, Space Status), Space creation and access (Creation Date, Creator Account Id, Creator Full Name, Public Link Permission, Public Link Count, Anonymous Access Status), Space activity and content (Last Activity, Content Count, Attachments), and Storage (Storage used (MB))

How to Use the Space Reports Feature?

1. Navigate to Confluence Administration > Settings

2. Select Space Reports from the navigation bar to access the Space Reports Page

3. Select the Create Reports button located in the top right corner of the page

4. Select Download to get your CSV file.

Note: ⚠️ Please note that reports may take a few minutes to complete, similar to other admin hub reports.

Verify your report

After downloading the CSV, confirm the data looks correct:

1. Open the CSV and check that the Storage used (MB) column contains values (not all zeros or blanks).

2. Cross-reference the total against your site storage dashboard: go to admin.atlassian.com > select your site > Site settings > Storage and compare the Confluence storage total to the sum of your CSV's "Storage used (MB)" column.

3. If the numbers differ significantly, the report may still be generating — wait a few minutes and download again. Small differences are normal due to timing.
