, and robotic media libraries.

Bacula Enterprise is based on a modern, multi-threaded and modular enterprise backup architecture. **It is especially stable, reliable, secure and massively scalable**.

Not only is Bacula massively scalable technically, but – due to having **no capacity-based licensing** – scaling costs are extremely low.
