I believe it simplifies the setup. Each drive can be mounted automatically using autofs. vchanger has autofs support so you can put any number of your disks in and issue update slots and it will find the disks mount them and inform bacula which volumes are available. Remember that each physical disk is a virtual autochanger magazine containing a user specified # of bacula volumes. I use fixed sized volumes in this case. I do not believe this works well with people that have max jobs or use volume once settings in their pool since there is a fixed number of volumes in each magazine. Like a tape autochanger it will not get around bacula wanting a volume that is not loaded in the virtual changer so you must handle that. Also for your case there is not a clean way to convert from existing volumes to virtual magizine volumes. I guess you can use copy jobs or something like that but if you have a working setup I would just go with that. BTW, I am using this at home where I only backup a few 100 GB. At work I am using primarily LTO2 tapes (105 of them now) and a 2 drive tape autochanger.
