I have question about how to perform clean Dedup Reconstruction. What is de first stap do you take? 

Do you need to mark disk libary offline for Maintance mode first?

When the Dedup DB reconstruction running what kind of jobs can interupt the proces? 

 

In my situation MA got crashed and after the crash started restore and then after restore automatic Dedup DB reconstruction. Sometimes is going wel but like today in the middle of the add record phase its failed with error: Unable to communicate with Auxiliary Copy process on MediaAgent. All commvault processes on the MediaAgent where running.

 

After the fail i stopped all processes on The MEdiaAgent en did restart. After restart the restore started again. 

@Egor Skepko DDB is a great feature but when it crashed can be very tricky to get back to work again.

 

I would recommend you read this article on manually recovering DDB  https://documentation.commvault.com/commvault/v11/article?p=12518.htm  AND if you do not get it to work, definitely open a support case with Commvault.

Hello @dude
