HBase Overview

You can perform a backup operation on the HBase database using the Hadoop Agent.

The Commvault software provides a single interface to back up all databases and tables in HBase.

Install the Commvault software on a Hadoop DataNode or a Hadoop Client Node. These nodes are referred to as data access nodes.

When you configure HBase, you specify one data access node as a master node. The master node must always be available. The master node is a control client that distributes the backup operations and restore operations among the data access nodes.

Key Features

  • Provides full and incremental application-consistent backups.
  • Handles TB to PB scales of data.
  • Maintains a copy of data for disaster recovery.

Terminology

This documentation uses the following terminology:

pseudoclient

A logical entity that represents one or more Hadoop clusters.

instance

An entity that represents one Hadoop cluster.

backup set

An entity that represents one Hadoop App, such as HBase.

subclient

A logical entity that defines the backup data.

namespace

An HBase database.

backup root

A staging directory where you put HBase data before you start a backup operation.

recover and apply

An option for restore operations to copy the data from the storage media directly to the database, without a staging location. After the restore operation completes, the application software recovers the database automatically.

recover and stage

An option for restore operations to copy the data from the storage media and stage it to a location. After the restore operation completes, the user must manually recover the database.
