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.

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. |
