Protecting HBase data using NetBackup

Using the NetBackup Parallel Streaming Framework (PSF), HBase data can now be protected using NetBackup.

The following diagram provides an overview of how HBase data is protected by NetBackup.

Also, review the definitions of terminologies.See NetBackup for HBase terminologies.

Figure: Architectural overview

Architectural overview

As illustrated in the diagram:

  • The data is backed up in parallel streams wherein the Region servers 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 HBase cluster and the NetBackup is enabled using the NetBackup plug-in for HBase.

    The plug-in is installed with the NetBackup installation.

  • For NetBackup communication, you need to configure a Big Data 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 Region servers, you can add or remove backup hosts. You can scale up your environment easily by adding more backup hosts.

  • The communication between the Hmaster and the backup hosts happens over SSH.

  • The NetBackup Parallel Streaming Framework enables agentless backup wherein the backup and restore operations run on the backup hosts. There is no agent footprint on the cluster nodes. Also, NetBackup is not affected by the HBase cluster upgrades or maintenance.
