managed, and controlled by the NetBackup media server while the
actual copy process is off-loaded to get the maximum benefits from the
DXi4500 replication capabilities.
Requirements
For NetBackup to use OST off host optimized replication when image
duplication is attempted, the following items are required:
• The source and destination storage units used for the copy are OST
disk volumes created from OST shares on the DXi4500. Source and
destination storage units could be created from the same DXi4500
or they could be located on different DXi systems.
• The DXi4500 is running in a normal state.
• The source image is deduplicated completely and tags are
generated for this file before optimized duplication is attempted.
• The target system must be configured to enable replication using
NetBackup OST optimized copy (see Chapter 8, DXi4500 Data
Services ).
Initiating Optimized Copy
The source and target storage units could be on the same DXi-Series
system or on a different DXi system. If the copy is to a different DXi,
ensure that there is connectivity from the source DXi to the destination
DXi.
The following steps assume that the storage units are located on
different DXi systems, though the same steps can be applied even for
storage units on the same DXi.
1 Ensure that the source and target DXi systems are running the latest
DXi software and NetBackup 6.5.2 or higher is running on the
media server.
2 At the NetBackup media server (refer to the NetBackup
Documentation):
a Configure NetBackup media server for OST.
b Install OST plug-ins on the media server.
3 At the source and target DXi systems:
a Configure OST storage servers.
