Performing Incremental or Cumulative Backups for Oracle

You can perform an incremental backup when the Oracle database is online or offline.

For more information on incremental backups, see Incremental Backups.

Before You Begin

  1. Depending on the database state, configure an online or offline subclient.
  2. Protect the Flash Recovery Area for the subclient.


  1. From the CommCell Browser, expand Client Computers > client > Oracle > instance.
  2. Right-click the subclient and click Backup.
  3. On the Backup Options for Subclient dialog box, select the backup type and job initiation:
    1. In the Backup Type section, choose the backup type.
    2. If you selected the Cumulative check box, specify the backup incremental level in the Oracle Incremental Level box.
    3. In the Job Initiation section, specify whether to run the backup now or if it will be scheduled.

      Note: If you selected Schedule, set up the schedule.

      For information on configuring a backup schedule, see Schedule Backups.

  4. Optional: Uniquely identify a backup.
    1. Click Advanced.
    2. On the Advanced Backup Options dialog box, click the Oracle Options tab, in the Oracle Tag box enter a unique tag.

      You can include variables in the tag. For supported tag variables, see Oracle Tag Variables.

      The Oracle tag you that you specify for the backup overrides the tag defined for the subclient.

    3. Click OK to close the Advanced Backup Options dialog box.
  5. Optional: Set the backup load distribution across disks. For more information, see Configuring the Disk Ratio for Oracle RMAN.
  6. Optional: View or customize the RMAN script that is generated from the selected options. For instructions, see Viewing Oracle Backup RMAN Scripts and Customizing Oracle Backup RMAN Scripts.
  7. Click OK to close the Backup Options dialog box.
