The \fBvchanger(8)\fR utility is used to emulate and control a virtual autochanger within the Bacula network backup system environment\&. Backup volumes stored on multiple disk filesystems are mapped to a single set of virtual slots\&. This allows an unlimited number of virtual drives and an unlimited number of virtual slots spread across an unlimited number of physical disk drives to be assigned to a single autochanger\&. This allows unlimited scaling of the cirtual autochanger simply by adding additional disk drives\&.

Vchanger is primarily deigned for use with removable disk drives\&. Its ability to interact with Bacula and determine removable drive mount points through udev allow for plug\-n\-play operation when attaching and detaching removable disk drives\&.

By default, vcahgner will invoke bconsole and issue commands to Bacula when certain operator actions are needed\&. When anything happens that changes the current set of volume files being used, vchanger will invoke bconsole and issue an \fIupdate slots\fR command\&. For example, when the operator attaches a removable drive defined as one of the changer\(cqs magazines, the volume files on the removable drive must be mapped to virtual slots\&.
