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 158 below). 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 ).
2. On the target system, create a local OST user (see Manage Users on page 346).
Caution:On the target system, make sure to create a local user on the Configuration>OST>
ManageUsers 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 251).
Note:Quantum recommends selecting the AvailableCapacity option when creating an LSU for
use with Automatic Image Replication.
4. On the source system, specify the target system that will receive the replicated data (see Adding a
Replication Target on page 270).
5. On the source system, create a remote OST user with the same user name and password that you used
in step 2 above (see Manage Remote Users on page 261).
Caution:On the source system, make sure to create a remote user on the Configuration>OST
>ManageRemoteUsers page.
6. On the source system, create a storage server and LSU, and enable the LSU for Automatic Image
Replication (see Adding a Storage Server on page 251).
For RemoteStorageServer and RemoteLSU, make sure to specify the storage server and LSU
created in step 3 above. Also, for RemoteUser, make sure to select the remote user created in step 5
above.
7. Configure storage lifecycle policies in NetBackup to control when automatic replication of the LSU
occurs (see the Symantec NetBackup Administrator's Guide).
