Promoting a copy to a primary copy

Each backup is assigned a primary copy. NetBackup uses the primary copy to satisfy restore requests. The first backup image that is created successfully by a NetBackup policy is the primary backup. If the primary copy is unavailable and a duplicate copy exists, select a copy of the backup and set it to be the primary copy.

NetBackup restores from the primary backup, and Vault duplicates from the primary backup. If your Vault profile performs duplication, you can designate one of the duplicates as the primary. In most circumstances, the copy remaining in the robot is the primary backup. When a primary backup expires, the next backup (if it exists) is promoted to primary automatically.

Use one of the following methods to promote a copy to a primary copy:

Promote a backup copy to a primary copy	See Promote a backup copy to a primary copy.
Promote a copy to a primary copy for many backups using the bpchangeprimary command	See Promoting a copy to a primary copy for many backups.

To promote a copy to a primary copy for many backups

You can also promote a copy to be a primary copy for many backups using the bpchangeprimary command. For example, the following command promotes all copies on the media that belongs to the b_pool volume pool. The copies must have been created after August 8, 2022:
```
bpchangeprimary -pool b_pool -sd 08/01/2022
```
In the next example, the following command promotes copy 2 of all backups of client_a. The copies must have been created after January 1, 2022:
```
bpchangeprimary -copy 2 -cl client_a -sd 01/01/2022
```
