Hi @ApK ,
Yes, the data should age off even though copy is inactive.
Please refer to this doc link
https://documentation.commvault.com/2023e/expert/marking_copy_as_inactive.html
If you mark a storage policy copy as inactive, your primary copy data can still be pruned without being copied and the copy cannot be used to transfer data to media.
Also, please refer to this Media Management config param below. This may help.
