Data Integrity validation failed for the data read from media. error

Hello @tstaba 

Thanks for the great question!

The following goes over a report you can run to show the Data integrity validation status in a report: 
https://documentation.commvault.com/2023e/expert/8915_data_integrity_validation_reports.html

This might provide some InSite as to what is going on and what may be causing you to fail.
When we are talking about data’s recoverability i would always recommend raising a case to support to review as if there is some level of corruption after write then we want to get on top of it ASAP. 

Please advise if this helps at all.

Kind regards

Albert Williams
