10.4 OST Configuration
Replication
Method
Description
Automatic
Image
Replication
(AIR)
If you are using Symantec NetBackup 7.1 or higher, you can configure an LSU
for Automatic Image Replication). If enabled, data on an LSU is automatically
replicated to a remote LSU that resides on a ETERNUS CS800 in a different
NetBackup domain. The timing of the duplication, as well as the backup
images that are duplicated, are determined by the storage lifecycle policies
(SLPs) configured in NetBackup. With AIR, you can specify a single
replication target.
Concurrent
Optimized
Duplication
For both optimized duplication and Automatic Image Replication, you can
optionally enable Concurrent Optimized Duplication. If enabled, as data is
written to the storage server, it is simultaneously replicated to the target
ETERNUS CS800. When optimized duplication or Automatic Image
Replication subsequently occurs, the operation is more efficient 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.
For more information about configuring the ETERNUS CS800 for optimized
duplication or Automatic Image Replication, see the ETERNUS CS800
NetBackup and Backup Exec OST Configuration Guide.
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) ETERNUS CS800 and then the source ETERNUS CS800 (see "Setting Up OST
Automatic Image Replication" on page 244). In addition, you must create storage lifecycle
policies (SLPs) in NetBackup that define when the automatic replication occurs and which
backup images are duplicated.
