Configuring a MongoDB Subclient to Back Up Oplog Dumps

You can configure a MongoDB subclient to back up the Oplog dumps by using a schedule policy. For more information about data protection schedule policies, see Creating a Data Protection Schedule Policy.

Schedule the oplog dump backups periodically based on the transactions on the MongoDB server.

Before You Begin

• You must have appropriate permissions to create a schedule policy. For information on permissions, see User Security Permissions and Permitted Actions by Feature: Schedule Policy.

• Set the oplog size to an optimal value so that the transactions are not overwritten before they are backed up by the scheduled oplog dump backups. For more information about setting the oplog size, see MongoDB documentation:

  • Replica Set Oplog

  • Change the Size of the Oplog

Procedure

1. From the CommCell Browser, expand Policies.

2. Right-click Schedule Policies, and then click New Schedule Policy.

   The New Schedule Policy dialog box appears.

3. In the Name box, type a name for the schedule policy.

4. From the Type list, select Data Protection.

5. From the Agent Type list, select Big Data Apps.

   2. In the Job Interval area, do the following:

      • Backup on file activity every: Specify the time interval for oplog backups.

      • Force a backup every: Specify the time interval to backup the dumps to media.

   3. To specify the number of oplog dump files after which you want to take incremental backups, on the Databases tab, select the Number of Archived Logs in Log Destination check box, and then specify the number.

      For more information about configuring threshold parameters for automatic schedules, see Creating an Automatic Schedule for Database Log Backups.

12. Click OK.

What to Do Next

• Perform an IntelliSnap backup on the MongoDB client before you start an oplog backup operation.

• If you want to disable oplog dump backups, you must add an additional setting. For more information, see Disabling Operation Log Dump Backups.
