OST
316 Quantum DXi8500 User’s Guide
To authenticate OST devices on a media server, you must create OST user
credentials. After you create the OST user credentials, enter them in the
backup application to authenticate OST devices on the media server.
To access the
OST page, click the Configuration menu, and then click
the OST tab.
The OST page contains the following tabs:
• Storage Servers
• LSU
• Manage Users
• Manage Remote Users
• Target IP Mapping
• DXi Accent
• OST Client Plug-In
Replicating OST Data
The DXi8500 can replicate (duplicate) OST data to another DXi using the
following methods:
• Optimized Duplication - With optimized duplication, backup
images on a storage server can be replicated to another storage
server on a DXi that resides in the same NetBackup domain. The
duplication occurs when it is initiated in NetBackup.
•
Automatic Image Replication (AIR)
- If you are using Symantec
NetBackup 7.1 or higher, you can configure an LSU for Automatic
Image Replication (see Task Overview: Setting Up Automatic Image
Replication on page 317). If enabled, data on an LSU is
automatically replicated to a remote LSU that resides on a DXi 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.
• 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 DXi. When optimized duplication or Automatic Image
Replication subsequently occurs, the operation is more efficient
