SD Design Introduction

The Bacula Storage daemon provides storage resources to a Bacula installation. An individual Storage daemon is associated with a physical permanent storage device (for example, a tape drive, CD writer, tape changer or jukebox, etc.), and may employ auxiliary storage resources (such as space on a hard disk file system) to increase performance and/or optimize use of the permanent storage medium.

Any number of storage daemons may be run on a given machine; each associated with an individual storage device connected to it, and BACULA operations may employ storage daemons on any number of hosts connected by a network, local or remote. The ability to employ remote storage daemons (with appropriate security measures) permits automatic off-site backup, possibly to publicly available backup repositories.
