Sharepoint online site collection storage metrics is showing incorrect data usage. For example It is showing 3 GB utilized space for document library with only 1.3 content.

I opened the document library in windows explorer and it is showing correct size there. Is there any timer job that needs to run before i come to conclusion and raise ticket to Micorosft Support

Check to see if the document library has versions enabled. While the total storage of the latest versions is only 1.3GB, it's likely that retaining a number of versions have pushed that amount up to 3GB. To minimize the storage impact, you can change the number of versions saved or disable versioning on that document library or list.

You can view the storage metrics page at https://contoso.sharepoint.com/sites/sitecollection/_layouts/15/StorMan.aspx. This will show both the site of the latest document as well as view the Version History with the size of each previous version.

  • Thanks Zach. It helped. I removed versioning and storage space decreased Oct 17, 2017 at 5:38
