To create concurrent multiple copies using the basic duplication tab

1. Indicate whether the images you want to duplicate reside on disk storage units only or on disk or media storage units.
2. Enter the number of drives to use for reading backup images for duplication.

   When you enter a number of read drives, the same number is entered into the destination Write Drives field. You must have an equivalent number of read and write drives available.

3. To use a media server that is different from the server that wrote the images, check Alternate Read Server and select the media server to use. (Alternate read servers apply to NetBackup Enterprise Server only.)

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

4. Select Multiple Copies, and then click Configure.
5. In the Multiple Copies dialog, select the number of copies to create.

   The number of copies you choose cannot exceed the number of copies that are specified in the Maximum Backup Copies field for the NetBackup master server. (Configured in NetBackup Management > Host Properties > Master Server > server_name > Global NetBackup Attributes.) By default, the value is two, which means one original backup and one copy.

6. If you want one of the copies to be the primary copy, select which copy is to be primary.

7. Specify the storage unit to be used for the duplication. When you specify the storage unit, the following applies:

   • If the Media Manager or Network Data Management Protocol (NDMP) storage unit has more than one drive, the source storage unit and destination storage unit can be the same.

   • NDMP storage units are supported only when one copy is created.

   • All storage units must be connected to the same media server.

8. Specify a volume pool for each copy.
9. 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.

10. 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.

11. 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.

12. Click OK to return to the basic Duplication tab.
13. 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.
14. To preserve multiplexing, select Preserve Multiplexing.

    See Duplication tab configuration options.

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

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

17. After you complete the dialog box, click OK.
