SharePoint Version-history Storage
The question it answers: How much storage does version history use per site, and which sites have high or unlimited version limits?
Every file save keeps a version. With a high or unlimited version limit and no expiry, old versions can consume a large share of a site’s storage - and extra SharePoint storage is bought per GB. This scan shows the tenant policy and the largest sites’ libraries that keep many versions.

| Data | A scan: it runs only when someone presses Run scan (or calls the API’s scan action) and can take minutes. The last result is kept until the next scan. It reads through PowerShell (Exchange Online or SharePoint Online), so the first load takes longer than a Graph report. |
| Licence | No extra licence needed. |
