Dell NetWorker 19.9 Administration Guide

Cloning save sets from the command prompt

Use the nsrclone command to clone save sets and volumes from a command prompt, or to script clone operations.

Script clone operations for any of the following scenarios:

• To control the conditions before cloning occurs. For example, following a specific event or test, or as part of a workflow.
• To control the actions after cloning has been successful. For example, deleting files, or moving data as part of a workflow.
• To control the cloning as part of an enterprise management scheduler that is independent of NetWorker scheduling or NMC.
• To create multiple clones. For example, clone 1 on disk, clone 2 to tape, each with specific dependencies, timing, and logic.
  NOTE:When using the scripted cloning feature, use the latest versions of NetWorker software. This minimizes the complexity of the logic in the cloning script.

The nsrclone command requires specific privileges which are assigned based on session authentication. NetWorker supports two types of session authentication. Token-based authentication, which requires you to run the nsrlogin before you run the command and authenticates the user that runs the command against entries that are defined in the External Roles attribute of a User Group resource. Classic authentication, which is based on user and host information and uses the user attribute of a User Group resource to authenticate a user. Classic authentication does not require an authentication token to run the command. For example, if you run the command without first running nsrlogin, NetWorker assigns the privileges to the user based on the entries that are specified in the Users attribute of the User Group resource. When you use nsrlogin to log in as a NetWorker Authentication Service user, NetWorker assigns the privileges to the user based on the entries that are specified in the External Roles attributes of the user Group resource. The NetWorker Security Configuration Guide provides more information about privileges Using nsrlogin for authentication and authorization provides more information.
