    In. Documentation I see a setting being depreciated for reconciliation of snapshots. What's was the reason for that? Is they're another way of doing that automatically or should we rely on a manual task for that? From documentation. The additional setting nRunSnapRecon has been deprecated in Commvault V11 SP8.

    I just looked at the CommVault Store and found a report called;

    @@@@@@@@@@@@@@@

    Snap Reconciliation Report

    Displays snap reconciliation statistics and provides the functionality of Delete, Force Delete, Do not Backup copy and Reconcile Arrays.

    @@@@@@@@@@@@@@@

    Not entirely sure of your end goal, but perhaps you can schedule the report to run every so often and take any administrative action more "proactively".

    It is a payed report, but you can also use the workflow available in the store as well for free which is probably a better tool for you to run on a regular bases with schedules.

    Hi Henke_H

    From the review of Documentation - https://documentation.commvault.com/commvault/v11/article?p=36955.htm

    Snap Reconcilation is still a feature in removing orphan snaps on the Filer or CommServe if there is a miss-match. 

    The only change is the removal of the Additional Setting "nRunSnapRecon" which was originally required as a check every 24 hours. 

    In most scenario you shouldn't need to run Snap reconciliation, and will only be needed if there is a miss-match. As this could put un-needed load on the Filer it could impact performance.

    The key should only be used in certain use case and should not be left enabled. 

    Regards

    Winston

    Inside the control panel > Array Managament you can click the button Reconcile Snapshots. T

    his compares the snapshots inside the Commserve Database with the snapshots on the volume in the Array. If the snapshots are not present on the Array then the mount status is 'Not Present in the Array'.

    The Reconcile Snapshots does not automatically delete any snapshots from the CS DB if they are 'Not Present in the Array'. The Backup Administrator will need to decide whether jobs need to be marked Do Not Copy or snapshots need to be deleted from the Commserve Database.
