To create concurrent images through the catalog node

1. In the NetBackup Administration Console, expand Master Server > NetBackup Management > Catalog.
2. In the Action field, select Duplicate.
3. Select the search criteria for the image you want to duplicate, and then click Search Now.
4. Right-click the image you want to duplicate and select Duplicate from the shortcut menu.
5. In the Setup Duplication Variables dialog, specify the number of copies to create.

   If enough drives are available, the copies are created simultaneously. Otherwise, the system may require operator intervention, for example, if four copies are to be created and there are only two drives.

6. Specify the priority of the duplication job for each copy, from 0 to 99999.

   A larger number is higher priority. All copies are duplicated at the same priority.

7. If you want one of the duplicated copies to become the primary copy, check the appropriate box.

   See Duplication tab configuration options.

8. Specify the storage unit where each copy is stored.
9. Specify the volume pool to which each copy is assigned.

   NetBackup does not verify in advance that the media ID selected for the duplicate copy is not the same as the media ID of the volume that contains the original backup. Because of this potential deadlock, specify a different volume pool to ensure that a different volume is used.

10. To change the retention level for the copy, select one of the retention level options.

    If No Change is selected for the retention period, the expiration date is the same for the duplicate copy and source copy.

    If you specify a numeric retention level, the expiration date for the copy is the backup date plus the retention period. For example, if a backup was created on November 14, 200x and its retention period is one week, the new copy's expiration date is November 21, 200x.

11. Specify whether the remaining copies should continue or fail if the specified copy fails.
12. Specify who should own the media onto which NetBackup writes the images.

    Any	NetBackup chooses the media owner, either a media server or server group.
    None	Specifies that the media server that writes to the media owns the media. No media server is specified explicitly, but you want a media server to own the media.
    A server group	All media server groups that are configured in your NetBackup environment appear in the drop-down list. Specifying a media server group allows only those media servers in the group to write to the media on which backup images for this policy are written.

13. If the selection includes multiplexed backups and the backups are to remain multiplexed in the duplicate, select Preserve Multiplexing.
14. Click OK to start duplicating.
15. Click the Results tab, and then select the duplication job just created to view the job results.
