Installation and System Requirements
To install Bacula, you need a system running a supported operating system like Linux, Windows, macOS, or UNIX, with Linux being the most used platform. Hardware requirements depend on the scale of the backup environment, but typically include sufficient CPU power, adequate RAM, and ample storage space to accommodate backup data and the Bacula catalogue database. A stable network connection is essential for seamless communication between Bacula components.
On the software side, a supported database system like MySQL, PostgreSQL, or SQLite is required for catalogue management, along with the necessary dependency libraries such as OpenSSL for encryption and zlib for compression. Backup media options include disks, tapes, or cloud storage, depending on the specific needs of your organisation.
