When a NetWorker server is utilizing a remote storage node, two nsrlcpd processes will be running on the storage node. The first one is responsible for communication between the NetWorker server and the storage node, while the second one is used to communicate with the PowerProtect DD appliance and the physical media library.

This behavior can occur when persistent naming is enabled on the storage node. When persistent naming is enabled and the storage node is rebooted, the library and tape drives may no longer be accessible because the persistent naming is lost.

Staging is used to make and keep a second copy of data at all times. This process is used to ensure data redundancy and provide additional protection against data loss or corruption.

Network Data Management Protocol (NDMP) is the technology used for backup and recovery with NetBackup Media Manager (NMM). NDMP is used to transfer data between the NetBackup server and the storage device.

The recover -iN command is used to simulate a recover operation. This command will show which files would be recovered if the recover command is run, but no data is actually recovered. The other options are not related to this command.

NWUI, or NetWorker User Interface, is a web-based graphical user interface for NetWorker. The URL syntax for NWUI is https://servername:9090/webui, where "servername" is the name of the NetWorker server.

The T flag on the Cloud in Dell EMC NetWorker represents that the save set will be cloned to a tape device. This allows for the save set to be stored on the tape device in addition to the cloud storage, providing additional backup and redundancy.

The cause of the behavior is that a vProxy is disabled. When a vProxy is disabled, it will not be available for selection in the drop-down menu during a backup action creation. This means that the vProxy cannot be used to perform backups of the VMware environment. To solve this issue the vProxy needs to be enabled.

It's worth mentioning that vProxy is a NetWorker feature that allows backups of VMware environments by communicating with vCenter or ESX servers. It uses the VMware APIs to access and back up virtual machines. And, it's also worth noting that vProxy backups can be directed to different types of devices like disk, tape, and deduplication devices like Data Domain and CloudBoost.

The "always" application-specific module should be specified when configuring backups on a client that requires the use of a directive, as this will ensure that certain files are included in the backup regardless of the backup level.

To create the desired configuration, you will need to use the Data Domain CLI (Command Line Interface) to access the DD Boost device and create the new appliance. Here are the steps:

Log in to the Data Domain CLI by entering the following command:

ssh ddboost@DD0

Enter the password "abc123" when prompted.

Once logged in, create a new DD Boost device named DD01.SU01 by entering the following command:

ddboost device create --name DD01.SU01 --type vmware --pool DO.VMware_Pool

Verify that the new device has been created by running the following command:

ddboost device show --name DD01.SU01

Configure the DD Boost device to connect to the PowerProcted DO series appliance by running the following command:

ddboost device set --name DD01.SU01 --dd-host DD0

Verify the configuration by running the following command:

ddboost device show --name DD01.SU01
