Rollback workspace

I suggest you open  a support ticket on this matter if you keep getting this issue: https://powerbi.microsoft.com/en-us/support/

Hi,  misaki233 

PowerBI Service does not have functions such as backup of historical data.
If reports and dashboards are lost or deleted by mistake, it may be difficult to roll back. You may need to seek help from the Microsoft team.
