10.4 OST Configuration
Replication Method
Description
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
Automatic Image Replication" on page 230
). 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 ETERNUS CS800 in a different NetBackup domain:
1. On the target system, add the source system to the list of allowed replication sources.
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 >
System > 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 232
).
Fujitsu Technology Solutions recommends selecting the
Available Capacity
option when creating an LSU for use with Automatic Image Replication.
