Figure: Copy creation order and hierarchy
example shows a configuration with hierarchical and
non-hierarchical storage destinations.
Let's examine the following aspects of this
example:
The example shows a
storage lifecycle policy that contains six storage destinations.
The numbers indicate the order in which the copies are created.

Hierarchy

| 1 |
Backup |
No indentation. The NetBackup Policy Execution Manager
(nbpem) runs backups to the backup
destinations first. |
| 2 |
Backup |
No indentation. |
| 3 |
Duplication |
No indentation; the copy uses either backup destination 1 or 2
as the source, depending on which is marked as the primary copy.
Duplications to the duplication destinations that run after the
source backup is created. The Duplication Manager (nbstserv) runs every 5 minutes (default) and looks
for backups eligible to duplicate. |
| 4 |
Hierarchical duplication |
Indented under 1; the copy uses backup destination 1 as the
source. |
| 5 |
Hierarchical duplication |
Indented under 2; the copy uses backup destination 2 as the
source. |
| 6 |
Hierarchical duplication |
Indented under 5; the copy uses duplication destination 5 as
the source. |
