See what’s changed in reports and data sources

Use version history to view and restore previous versions of a report or data source.

As you edit a report or data source, Looker Studio keeps a history of your changes. You can also manually save a version at any time. Version history lets you view, restore and delete previous revisions. You can also see when the revision was created, and by whom.

Unable to see a particular version of your file?

Version history is not available for revisions made prior to February 15th, 2019.

The revisions for your reports or data sources may occasionally be merged to save storage space.

Limits of version history

  • In order to see version history, you must have edit permission to the report or data source .
  • Version history is not preserved for copies of a report.
  • Restoring a report does not affect its data sources. If you restore the report to an earlier version that is incompatible with its data sources, you may need to restore those data sources to compatible versions, as well.
  • Changes to data source credentials can't be restored. You must apply credential changes directly to the current version.
