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
). 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
).
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
).
Note:
Quantum recommends selecting the
Available Capacity
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
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
Manage Remote Users on page 261
).
Caution:
On the source system, make sure to create a
remote
user on the
Configuration > OST
> Manage Remote Users
page.
6. On the source system, create a storage server and LSU, and enable the LSU for Automatic Image
Adding a Storage Server on page 251
).
For
Remote Storage Server
and
Remote LSU
, make sure to specify the storage server and LSU
created in step 3 above. Also, for
Remote User
, 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
).
