To create concurrent multiple copies using the advanced configuration options

1. On the Duplication tab, select Advanced Configuration.
2. To use a server that is different from the server that wrote the images, select Alternate Read Server. (Alternate read servers apply to NetBackup Enterprise Server only.)

   If robots (or drives) are shared by more than one media server, you can designate a different media server to read the original backups than the media server that wrote the backups.

   If you select Alternate Read Server, an Alternate Read Server column heading appears in the SOURCE area.

3. To add a destination media server and duplication rules for that server, click New.

   If you selected Alternate Read Server on the Duplication tab, the Duplication Rule dialog box has fields for both source Media Server and Alternate Read Server. If you did not select Alternate Read Server, only a source Backup Server field appears.

4. Select the source Backup Server or, if you selected Alternate Read Server on the Duplication tab, select the source Media Server.
5. If you selected Alternate Read Server on the Duplication tab, select an Alternate Read Server. (Alternate read servers apply to NetBackup Enterprise Server only.)

   The source media server and alternate read server may be the same.

6. Select the number of copies to create.

   You can create up to four or the number of copies that are specified in the Maximum Backup Copies field for the NetBackup master server (if less than four). (Configured in NetBackup Management > Host Properties > Master Server > server_name > Global NetBackup Attributes.) By default, the value is two: one original backup and one copy.

7. If you want one of the copies to be the primary copy, select which copy is to be primary.
8. Specify the storage unit to be used for the duplication.

   In addition, all storage units must be connected to the same media server.

9. Specify a volume pool for each copy.
10. Specify the retention level for each copy.

    See Assigning multiple retentions with one profile.

    When the retention period expires, information about the expired backup is deleted from the NetBackup and Media Manager catalog, the volume is recalled from off-site storage, and the backup image is unavailable for a restore.

11. Indicate what action is to be taken if a copy fails.

    In Vault, if you choose Fail All Copies, all copies of that image fails, independent of the success or failure of other image copy operations. The next time the vault profile runs, Vault again tries to duplicate the image if the following conditions are true:

    • The image is selected.

    • The Vault profile did not eject the primary backup.

    By default, the option is configured to Fail All Copies in Vault.

    If you choose Continue for all copies, Vault considers the duplication job successful if any of the copies succeed. However, it is possible that a copy of the image may never get vaulted. It is probable that at least one copy will succeed, but it may not be the copy that is assigned to the off-site volume pool.

12. Specify who should own the media onto which you are duplicating images:

    Any	NetBackup chooses the media owner.
    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. Click OK to return to the Duplication tab.
14. Specify the priority of the Vault duplication jobs, from 0 to 99999. A larger number is higher priority. All duplication jobs for the profile run at the same priority.
15. Indicate whether you want to Preserve Multiplexing.

    See Duplication tab configuration options.

16. Select Duplicate Smaller Images First (applies only to disk backup images) to duplicate images in smallest to largest order.
17. Check Expire Original Disk Backup Images... and then enter the number of hours after this Vault session completes to expire the disk images.

    Use this option to free up space on the disk for subsequent backup images. Be sure that you allow enough time for the duplication operation to complete.

    If the duplication of a disk image fails, the disk image does not expire.

18. Click OK.
