Does the DDB Verification Job do an equivalent work as The Data Verification Job? Is there any difference between them? I picked a job for Data Verification, but I didn't run Data Verification operation from Storage Policy All Tasks menu and today I realize that the picked job was verified. 

 

There are some schedule policies to run a Incremental Verification of existing jobs on disk and deduplication database. 

And there is menu option to run a Data Verification from Storage Policy.

Yep, the underlying process is the same, we are validating data health on storage in both processes, one targets only the jobs tied to a DDB engine, the other can be at an individual job level or non dedupe policy jobs. 
 

We have some information on these processes here: 

DDB Verification: https://documentation.commvault.com/2022e/expert/100399_data_verification_of_deduplicated_data.html

 

Data Verification: https://documentation.commvault.com/2022e/expert/8901_data_integrity_validation.html

Let me know if this helps.

Hi!

So in this case, if DDB verification is run, it's not needed to run data verification on a SP copy or job basis?

@PedroRocha correct, I wouldn’t bother doing it at an individual job level personally if I was frequently doing DDB Verification jobs.
