To install a virtual CloudBoost appliance on a VMware ESXi host, the backup administrator must deploy an OVF template. This will deploy the appliance on the ESXi host and configure the settings for the appliance.

To configure PSS for a client to have 3 PSS for save set '/data1' and 5 PSS for save set '/data2', the administrator can use the following command:

PSS:streams_per_ss=3,/data1, 5,/data2

This command sets the number of parallel save streams (PSS) for each save set. The option "streams_per_ss" is used to specify the number of parallel save streams for each save set, and the path of the save set is specified after a comma. In this case, 3 PSS are set for the save set '/data1' and 5 PSS are set for the save set '/data2'.

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.

A datazone is a NetWorker component composed of a single NetWorker Server, its clients, and storage nodes. It is used to define a group of systems and storage nodes that will share the same configuration. The media pool, save set, and protection group are all related to NetWorker, but they are not components of a datazone.

The error "Cannot contact a portmapper on port 7937" indicates that the portmapper service, which is required for the NetWorker Extended Client installation, is not running on the Linux host. The recommended action to resolve this issue is to install the lgtoserv-[version] rpm package and reinstall the Extended client. The other options are not related to this process.

The Dell EMC Cloud Tier feature allows customers to offload data from a PowerProtect DDVE to a cloud storage provider such as AWS S3. This feature provides a cost-effective way to store data in the cloud and helps to reduce storage costs associated with on-premises storage.

To configure an AFTD device on "StorageNodeA" with the name "OracleBackup" using the folder "D:\AFTD" to the pool "Default", the administrator can use the Data Domain CLI (Command Line Interface) to access the Data Domain system and create the AFTD device. Here are the steps:

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

ssh admin@StorageNodeA

Once logged in, create a new AFTD device named "OracleBackup" by entering the following command:

ddboost afd create --name OracleBackup --pool Default --folder D:\AFTD

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

ddboost afd show --name OracleBackup

To make sure that the Oracle backups only use the specific storage node, you can assign the AFTD device to the Oracle backup host by running the following command:

ddboost afd set --name OracleBackup --host OracleBackupHost

Verify the configuration by running the following command:

ddboost afd show --name OracleBackup

To make sure that the StorageNodeA is a dedicated storage node, you can configure the storage node to only allow the OracleBackup host to use the AFTD device by running the following command:

ddboost host access add --host OracleBackupHost --afd OracleBackup

Finally, the administrator should select the “Apply” button to save the configuration.
