In the NetWorker configuration, it is possible to add two different DDBoost devices using different users who are created on the DDR as you can see on the following listing: sysadmin@ddve03# user show list User list from node "localhost".

During the cloning process, the Fast Copy mechanism on the DDOS layer does not have the possibility to change the UID/GID of copying files.
Use the same user to connect the Boost Devices from the same DDR.1. Log in to the Data Domain device over SSH using the sysadmin account.2. Change the storage-unit (SU) owner using the following command: ddboost storage-unit modify SU02 user username sysadmin@ddve03# ddboost storage-unit modify SU02 user boostuser01 The 'ddboost modify' command should not be used to modify the 'user' of a BOOSTFS storage-unit. Are you sure? (yes|no) [no]: yes ok, proceeding. Storage-unit "SU02" modified for user "boostuser01". 3. You can confirm that the setting was changed with: ddboost storage-unit show sysadmin@ddve03# ddboost storage-unit show Name Pre-Comp (GiB) Status User Report Physical Size (MiB) SU01 0.0 RW boostuser01 - SU02 0.0 RW boostuser01 - --------- -------------- ------ ----------- --------------- 4. Log in to the NetWorker Management Console and update the device under Devices->Devices. The boost user details can be changed in the Configuration tab of the device properties. 5. Change the user and password to the one set with the ddboost storage-unit modify command run earlier on the Data Domain. 6. Unmount and remount the device to confirm it mounts successfully using the new credentials.
