Note
You should enable the DD Retention lock option on the MTree in Data Domain Console prior to enabling WORM storage lock in CommCell Console.
Configure the WORM storage lock on the Data Domain Boost Storage Library. For more information, see Configuring WORM Storage Mode on Disk Libraries. The WORM lock days configured in Commvault storage pool should be set between the Retention period min and Retention period max values set in Data Domain Console under the Data Domain Retention Lock setting. WORM Lock days is shown on the Storage Policy Copy Properties dialog box. The Data Domain Retention Lock can be set to either Governance mode or Compliance mode.
Data Domain Retention Lock is set to a minimum retention period that is one day less than the retention set in the Commvault storage policy and a maximum retention period that is greater than the retention set in the Commvault storage policy. For example, if the retention period in the Commvault storage policy is 14 days, then set the minimum retention to 13 days and the maximum retention to 16 days in Data Domain Console.
Note that the files will be WORM-locked for the number of days specified in the Commvault storage policy.
Note
Set the minimum retention to a lower value in Data Domain Console to compensate for the delay in running auxiliary copy jobs. For example, if retention is set to 14 days for auxiliary copy in Commvault, set the minimum retention to 2 days in Data Domain Console.
