Oracle RAC with NetBackup best practices
The Real Application Clusters (RAC) option allows multiple concurrent instances to share a single physical database.
Oracle database backup and recovery is more difficult as databases grow in size and greater demands on database availability limit the time to perform backups. Often the backup time window is too short to accommodate a complete backup process by using only one backup node in the cluster. Database administrators need more efficient methods to complete these large backups in the allotted time. For the Oracle RAC database, Oracle can split the backups into pieces and send them in parallel from multiple nodes, which shortens the processing time.
This section describes the methods that can be used to backup the Oracle RAC database. You can use one node to backup the database or balance the backup load across multiple nodes of an Oracle RAC database.
