Cloning volumes from the command prompt

Volume cloning is the process of reproducing complete save sets from a storage volume to a clone volume. Use the nsrclone command to clone save set data from backup or archive volumes.

1. Optionally, use the nsrlogin command to authenticate a user and generate a token for the
   Using nsrlogin for authentication and authorization provides more information.
2. Use the mminfo command or the NetWorker Administration window to determine the name of the volume that contains the save sets that you want to clone.
   • To use the NetWorker Administration window, perform the following steps:
     1. Click Media.
     2. In the expanded left pane, select either Disk Volumes or Tape Volumes.
     3. In the right pane, record the name that appears in the Volume Name column.
   • To use the mminfo command to display volumes. For example, to display a list of all the available volumes, type the following command:

     mminfo -mv
     state volume                  written  (%)  expires     read mounts capacity volid      next type
            bu_iddnwserver2.iddlab.local.001 46 MB 100% 04/04/2015 0 KB 0     0 KB 16193908      0 adv_file
            bu_iddnwserver2.iddlab.local_c.002 0 KB 0% undef  0 KB     0      0 KB 4294384030    0 adv_file

   NOTE: For disk type devices, the amount of data on the device (DD, DDCT, and AFTD) by Networker and reported by mminfo for the written in the volume record, must match the disk usage on the file system directory where the device path is configured.
3. From a command prompt on the NetWorker server, use the nsrclone command to clone the save sets on a volume. For example to clone save sets to volume in the default clone pool, type:
   nsrclone -v -b Default backup.001

   where:

   • backup.001 is the name of the volume that contains the source save sets.
   • The clone pool that the clone operation uses to write the clone save sets is the Default clone pool.
