Performing a DB2 MultiNode Delta or Differential Backup

A differential backup contains only the data that is new or has changed since the last full backup. Differential backups use less media and resources than full backups.

For more information on differential backups, see Differential Backups.

Before You Begin

For DB2 pureScale backups, share the following directories on all the pureScale nodes:

• sDB2_ARCHIVE_PATH

• sDB2_AUDIT_ERROR_PATH

• sDB2_RETRIEVE_PATH

You can view the directory path from the /etc/CommVaultRegistry/Galaxy/Instance001/Db2Agent/.properties file.

Procedure

1. From the CommCell Browser, expand Client Computers > client> DB2 MultiNode >instance > backup_set.

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, select Differential.

   2. 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. Click OK to close the Backup Options dialog box.
