Dell NetWorker 19.9 Administration Guide

Configuring block based backups

1. Enable the block based backup feature when you use one of the following methods to configure the client:

   • NetWorker Client Configuration wizard

   • Client Properties window

   • The nsradmin program

2. Select the following fields to enable the block based backup feature:

   • Client direct (selected by default)

   • Block based backup

3. [Optional] To set parallel save streams if the target or destination is Data Domain:
   1. In the NetWorker Client Properties dialog box, on the Globals (1 of 2) tab, select Parallel save streams per save set.
   2. On the Apps & Modules tab, in the Save operations field, type one of the following values:
      • PSS:streams_per_ss=2,*
      • PSS:streams_per_ss=4,*

        This is the default value.

      NOTE:Parallel save streams is applicable only for full backup.
   3. To perform parallel save streams enabled backups for block based backup volumes:
      1. In NMC, under Server, select User Groups.
      2. Right click Application Administrators and select Properties.
      3. In the User Group Properties Application Administrators window, under Users, add user=system,host='hostname'.
   NOTE:Consider the following notes about parallel save streams and save sets:

   • When a backup contains more than four save sets, the parallel save streams value must be either greater than or equal to the number of save sets.
   • The parallel save streams per save set value is the same for all the save sets of the client, that is, you cannot set the value of one save set to 2 and the value of another save set to 4 on the same client.
