Backing up data

Backing up data using Plug‑in for Oracle that has been set up for use in a Virtual Client is relatively simple. On the NetVault Backup Selections page, open the Virtual Client node, open Plug‑in for Oracle, and then select the Oracle Server Instances (or the items contained within) for inclusion in the backup.

Restoring data

Restoring data to a Virtual Client is conducted in the same manner as a restore performed to a traditional NetVault Backup Client. All options available for a restore with Plug‑in for Oracle are also available for Failover Clustering environments, and data selection is performed in the same way as well. The only difference is that restorable backups of a Virtual Client are displayed on the Create Selection Set page under the name of the Virtual Client, not the specific NetVault Backup Client or node that was active during each backup. When a restore job is initiated, NetVault Backup will communicate with all member Clients to determine which machine is currently in control of the failover cluster, and then target this machine for the restore.
 
 
*IMPORTANT: The Restore Backup taken from NetVault Backup Client field on the Configure dialog must contain the network name that resolves to the virtual IP of the failover cluster; otherwise, restores will fail. For more information on using the Configure dialog, see Configuring the plug-in.
Additionally, you can restore a NetVault Backup Virtual Client to a non-clustered (standalone) NetVault Backup Client.
When restoring data to a Virtual Client, Dell recommends that you select the applicable Virtual Client from the Target Client list in the Create Restore Job page.
All the instructions offered in reference to performing a restore can be used in the recovery of a Virtual Client. For more information on restoring a NetVault Backup Virtual Client, see the various sections in Restoring data.

Oracle Data Guard – an overview

Oracle’s Oracle Data Guard “ensures high availability, data protection, and disaster recovery for enterprise data. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions. Data Guard maintains these standby databases as copies of the production database. Then, if the production database becomes unavailable because of a planned or an unplanned outage, Data Guard can switch any standby database to the production role, minimizing the downtime associated with the outage. Data Guard can be used with traditional backup, restoration, and cluster techniques to provide a high level of data protection and data availability.”
With Data Guard, administrators can optionally improve production database performance by offloading resource-intensive backup and reporting operations to Standby Database Servers. In addition, backups can be used to recover either the Primary or Standby Database Server, regardless of whether the backups were taken from the Primary or the Standby Database Server.
Plug‑in for Oracle provides support for a limited number of Oracle versions in a Data Guard environment. The installation, configuration, backup, and restore procedures differ slightly in a Data Guard environment. This section offers specifics on how the plug-in operates in a Data Guard environment.
For a complete list of supported Oracle versions and platforms in a Data Guard environment, refer to the Dell NetVault Backup Plug-in Compatibility Guide.
 
 
*NOTE: The plug-in’s RMAN backup method is the only method supported in Data Guard environments. Unless outlined in the sections that follow, backups and restores performed with Plug‑in for Oracle for Data Guard physical or standby databases are the same as those performed with non-Data Guard databases.
