Protecting MongoDB data using NetBackup
Using the NetBackup Parallel Streaming Framework (PSF), MongoDB data can now be protected using NetBackup.
The following diagram provides an overview of how MongoDB data is protected by NetBackup.
Also, review the definitions of terminologies.See NetBackup for MongoDB terminologies.
As illustrated in the diagram:
The data is backed up in parallel streams wherein the data nodes stream data blocks simultaneously to multiple backup hosts. The job processing is accelerated due to multiple backup hosts and parallel streams.
The communication between the MongoDB cluster and the NetBackup is enabled using the NetBackup plug-in for MongoDB.
The plug-in is available separately and must be installed on all the backup hosts.
For NetBackup communication, you need to configure a BigData policy and add the related backup hosts.
You can configure a NetBackup media server, client, or master server as a backup host. Also, depending on the number of replica sets or sharding, you can add or remove backup hosts. You can scale up your environment easily by adding more backup hosts.
The communication between the configuration server, secondary nodes and the backup hosts happens over SSH.
The NetBackup Parallel Streaming Framework enables a thin client-based, agentless backup wherein the backup and restore operations run on the backup hosts. The NetBackup thin client binary is automatically pushed to the MongoDB cluster nodes during the backup and recovery operations. This thin client is automatically removed after the backup and recovery operations complete. There is no agent management required on the cluster nodes. Also, NetBackup is not affected by the MongoDB cluster upgrades or maintenance.
