Creating a DB2 Data Subclient

By default, the default subclient includes both data and the logs for the backup.If you want to backup only the data, then create a separate subclient for data backups.

Before You Begin

Configure a backup set for the DB2 database.

Procedure

1. From the CommCell Browser, expand Client Computers > client > DB2 > Instance.

2. Right-click the backup_set, point to All Tasks, and then click Create Subclient.

   The Create New Subclient dialog box appears.

3. In the General tab, in the Subclient name box, type a name for the subclient.

4. On the Content tab, select the following options:

   1. Select the Data check box.

   2. Select the Online Database option.

   3. Click Yes on the Warning dialog box.

   4. From the Current Database View, select the database objects you want to include.

5. On the Storage Device tab, from the Data Storage Policy list, select the storage policy that you want to use.

6. On the Advanced Options tab, clear the Backup Log Files check box.

7. Optional: Select the subclient options.

   Run scripts before or after the backup

   You can choose to run the post-process script even if the backup job failed.

   To pass the database instance name to the script, see Passing the Instance Name to Pre and Post Scripts for Databases.

   On the Pre/Post Process tab:

   1. In the PreBackup Process box, type the full path name for the script.

   2. In the PostBackup Process box, type the full path name for the script.

   Use compression to optimize backup storage

   On the Advanced Options tab, select the Use Db2 compression check box.
