Learn Bacula (an enterprise open source backup suite with a distributed architecture of Director, Storage Daemon, File Daemon, and Catalog) from the fundamentals to production-grade: prerequisite skills & environment setup, background history & why you need it, core concepts & main architecture, installation & basic configuration, bconsole & job control, FileSet & include/exclude, pool volume & storage, schedule & job types, restore workflow, verify & autoprune, database & application backup, tape & storage management, daemon security & auth, TLS & network security, hardening & least privilege, multi-client & multi-director, troubleshooting & debug, Bacula 15.0.x & the latest features, enterprise vs community, tape library & cloud integration, performance & monitoring, roadmap & community, to the alternative ecosystem & final reflection across 23 episodes.
Before touching bconsole and bacula-dir, you need to master basic Linux admin (daemons, users, file permissions), understand the concept of full/incremental backups and TCP networking, and prepare a server with Bacula 15.0.4 and the File Daemon client. In this episode the entire environment is visualized and verified.

This episode reviews the history of Bacula from its birth in 2000 as a fork of the V6 project, its dual-license model of AGPL (Community) and commercial (Enterprise), to its evolution into the 15.x series with catalog and performance improvements. You will also understand why Bacula is needed: distributed architecture, cross-platform tape support, and policy flexibility.

This episode dissects the Bacula architecture: the Director as the job controller, the Storage Daemon as the media manager, the File Daemon as the client agent, and the Catalog as the metadata database. You will also get to know the bacula-dir, bacula-sd, bacula-fd, and bconsole components, the configuration under /etc/bacula/, and the role of the Job/Client/FileSet/Pool/Schedule/Storage resources.

This episode guides you through installing Bacula 15.0.4 on Debian/Ubuntu and RHEL, creating the PostgreSQL catalog database, and writing the minimal bacula-dir.conf, bacula-sd.conf, and bacula-fd.conf configuration. You will also validate the configuration with bacula-dir -t and start the three daemons for the first time.

This episode helps you master bconsole, Bacula's interactive console: authentication to the Director, the status, list, run, restore, and cancel commands, plus running your first backup job and monitoring its results through list jobs and list files.

This episode teaches you how to structure Bacula FileSets: choosing the directories to back up, include/exclude rules with wildcards and regex, the exclude = yes option, and verifying results through list files jobid=... and previewing with estimate before a job runs.

This episode teaches Bacula media management: the Pool concept as a group of volumes, the Recycle and AutoPrune retention parameters, volume size, storage device types (File and Tape), and the label and mount operations for preparing new media and checking storage status.

This episode teaches Bacula scheduling with the Schedule resource (weekly Full, daily Incremental), the four main job types (Backup, Restore, Verify, Admin), and the three retention layers — File, Job, and Volume — along with the auto-prune mechanism that keeps the catalog lean.

This episode guides you through the Bacula restore workflow: building an interactive restore job from bconsole by selecting client, FileSet, and time, directing results to the original or an alternative location with where= and replace=, plus practicing routine restore drills into a test directory with file verification.

This episode teaches Bacula data verification: Verify jobs to compare the client's contents with the catalog records, checking volumes and autopruning stale media, maintaining catalog consistency with safe prune and purge, and protecting the catalog with scheduled backups.
