Bareos (Backup Archiving Recovery Open Sourced) is a reliable, cross-network open source software for backup, archiving and recovery of data for all well-established operating systems. Emerged from the Bacula Project in 2010, Bareos was and is actively developed as a fork and enriched with lots of new features. After a short introduction about the Bareos architecture and terminology, this session will introduce how to extend Bareos with Plugins written in Python.
