1. Download the ReconstructDDB.xml file and save it on the computer from where you want to execute the command.

2. Execute the following command from the <software_installation_directory>/Base folder after substituting the parameter values.

   qoperation execute -af download location\ReconstructDDB.xml -copyName copyname -storagePolicyName SPname -SIDBStoreId DDBStoreID -flags 0 -useScallableResourceManagement true/false

   Where,
   • copyName: Name of the stoarge policy copy
   • storagePolicyName: Name of the storage policy
   • SIDBStoreId: The ID of the deduplication databasae that you want to recover.
   • useScallableResourceManagement: Define to use scalable reosurce allocation when reconstructing the DDB. Valif values are: true and false.

   For example: To recover a DDB with ID 27239 that belongs to storage policy SP1 and copy Copy1 without using scalable resource allocation, execute the following command:
