Replicating OST Data
The ETERNUS CS800 can replicate (duplicate) OST data to another ETERNUS CS800
using the following methods:
●
Optimized Duplication
- With optimized duplication, backup images on a storage
server can be replicated to another storage server on a ETERNUS CS800 that resides
in the same NetBackup domain. The duplication occurs when it is initiated in
NetBackup. With optimized duplication can specify up to two replication targets.
●
Automatic Image Replication (AIR)
- If you are using Symantec NetBackup 7.1 or
higher, you can configure an LSU for Automatic Image Replication (see
Overview: Setting Up Automatic Image Replication" on page 243
). 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.
