because a portion of the required data has already been replicated
to the target storage server.
It is important to remember that, with Automatic Image Replication, the
local and remote LSUs reside in
different
NetBackup domains. This
differs from optimized duplication, which occurs between two LSUs
residing within
the same
NetBackup domain.
Note: For more information about configuring the DXi8500 for
optimized duplication or Automatic Image Replication, see the
DXi-Series NetBackup and Backup Exec OST Configuration
Guide
(6-67079).
Note: For information about configuring NetBackup for optimized
duplication or Automatic Image Replication (also referred to as
duplicating images to a remote master server domain), see the
Symantec NetBackup Administrator's Guide .
Task Overview: Setting Up Automatic Image Replication
Setting up Automatic Image Replication (AIR) requires that you first
configure the target (remote) DXi and then the source DXi (see
Figure 177 ). In addition, you must create storage lifecycle policies (SLPs)
in NetBackup that define when the automatic replication occurs and
which backup images are duplicated.
To automatically replicate (duplicate) all data on an LSU to a remote LSU
that resides on a DXi in a different NetBackup domain:
1
On the target system, add the source system to the list of allowed
replication sources (see Replication Receive on page 312).
2 On the target system, create a local OST user (see Manage Users on
page 333).
Caution: On the target system, make sure to create a local user
on the Configuration > OST > Manage Users page.
3
On the target system, create a storage server and LSU to receive the
replicated OST data (see Adding a Storage Server on page 321).
