The following article presents the Bacula Enterprise Hadoop Distributed File System (HDFS) Plugin.

Apache Hadoop is a distributed platform designed for large-scale storage and processing, and HDFS is the storage layer used to spread data across the nodes of a cluster. For the official project references, see Apache Hadoop and Apache HDFS.

In real deployments, HDFS often stores critical datasets, application exports, and data lakes that must remain available even when nodes fail or administrative mistakes happen. Protecting that data requires more than a filesystem copy: it needs consistent snapshots, repeatable job control, retention, and restore procedures that fit into the operational model of the cluster.

Bacula Enterprise provides that control in a centralized way. The HDFS plugin lets the Bacula File Daemon act as an HDFS client through the Java SDK, connects to the target system using the configured authentication and connection parameters, and protects the data with snapshot-based full, incremental, and differential backups. Backups can be restored back into HDFS or written to a local filesystem when needed.
