Dell NetWorker 19.9 Administration Guide

Creating a Client resource with the Client Backup Configuration wizard

The Client Backup Configuration wizard enables you to quickly configure a Client resource with a limited set of key backup options. Follow these steps to configure a file system backup and an OS-X host.

1. In the NetWorker Administration window, click Protection.
2. In the expanded left panel, right-click Clients, and then select New Client Wizard.
   The Client Backup Configuration wizard appears.
3. In the Client Name box, type either the hostname or the Fully Qualified Domain Name (FQDN) of the client.
   It is recommended that you specify the FQDN of the host. The FQDN of a NetWorker Client can contain up to 255 characters. For OS cluster hosts, type the FQDN of the virtual host.

   For application cluster hosts, type the FQDN of the application cluster host.  For example:

   • For an Oracle cluster, type the RAC hostname.
   • For an Exchange IP DAG, type the DAG name.

   The application module administrator guides provide more information.

   NOTE: If the Client Configuration wizard cannot resolve the specified hostname, an error message appears after you click Next.
4. Optionally, in the Comment box, type a description of the client.
   If you are creating multiple client resources for the same NetWorker client host, then use this attribute to differentiate the purpose of each resource.
5. In the Tag box, type one or more tags to identify this Client resource for the creation of dynamic client groups for data protection policies.
   Place each entry on a separate line.
6. In the Type box, select Traditional NetWorker client.
7. Optionally, from the Group list, select a group for the Client resource.

   The group to which the client belongs determines the workflow that is used to back up the client.

   NOTE:You can also assign the client to one or more groups after you create the Client resource.
8. Click Next.
9. On the Specify the Backup Configuration Type page, select Filesystem, and then click Next.
10. On the Select the NetWorker Client Properties page, configure the following options:

    Option	Description
    Priority	Enables you to control the order in which the NetWorker server contacts clients for backup. During a backup operation, the NetWorker server contacts the client with the lowest priority value first. If you do not specify a priority for the client resources, then the backup order is random. The default value is 500. While the Priority attribute specifies the order of client contact, many variables affect the order in which clients complete their backups. For example: The backup operation on a client does not begin until the worklists for each of the save sets on the client are complete. The amount of work can vary greatly from one client to the next. If a client stops responding and times out, then the backup operation puts the client backup at the end of the backup order list. The only way to guarantee that the backup of one client occurs before the backup of another client is to configure the workflows for the clients to start at different times.
    Parallelism	Specifies the maximum number of data streams that a client can send simultaneously during a backup action. Data streams include backup data streams, savefs processes, and probe jobs. The default value is different for the NetWorker server than it is for all other client resources: For the NetWorker server client resource, the default value is 12. This higher default value enables the server to complete a larger number of index backups during a Server backup action. For all other clients, the default value is 4. To avoid disk contention for clients other than the NetWorker server, specify a value that is the same as or fewer than the number of physical disks on the client that are included in the backup. The NetWorker Performance Optimization Planning Guide provides more information about recommended client parallelism values and performance benefits.
    Remote Access	Specifies a list of the users that have access to perform remote access operations. For example, users that can perform a directed recovery of backup data that originated on this host.
    Data Domain Interface	Specifies the protocol to use if you send the backup data to a Data Domain Device. Available selections are IP, Fibre Channel, or Both. NOTE:Mac OS X clients only support the IP protocol.
    Block Based Backup (BBB)	Enables Block Based Backups for the host. When you select this option, you must also select the Client Direct. This option applies to Linux only. NOTE:The Block Based Backup chapter provides complete information about how to configure a host for BBB backups.
    Client Direct	Allows the client to try to directly connect to the backup storage device, instead of connecting to a NetWorker storage node. If a direct connection is not possible, then the backup operation connects to the NetWorker storage node that you configure to accept data from the client.
    Parallel Save Streams (PSS)	Enables NetWorker to use multiple parallel save streams to backup each save set defined for the client, to one or more destination devices. PSS does not support Checkpoint Restart backups.

11. Click Next.
12. On the Select the File System Objects window, select the file system objects to backup.
    To avoid the over consumption of memory, NetWorker limits the number of files that you can view when you browse a directory that contain a large number of files, for example, 200,000 files. When NetWorker determines that displaying the number of files will exhaust memory resources, NetWorker will display a partial list of the files and a message similar to the following appears: Expanding this directory has stopped because the result has too many entries

    NOTE: When you select all file system objects, the ALL value appears in the Save set attribute for the Client resource. The ALL save set includes local and mounted volumes.
13. On the Backup Configuration Summary page, click Create.
14. On the Client Configuration Results page, review the results of the client configuration process, then click Finish.
