Well, if bacula properly supported disks as backup media, that may have 
been true. In reality they'll need to run "vchanger initmag" and "label 
barcodes/update slots" every time, so the amount of plug'n'playing you 
can achieve is somewhat limited by that.

The advantage of permanently mounted drives is bacula will run pretty 
much unattended if your storage as a single partition. We have one 
server where I am gradually replacing 4TB drives with 8TB 'archive' 
drives -- ZFS filesystem lets you do that with no downtime. It also lets 
you configure your disks into software raid sets: very handy when using 
commodity SATA drives that tend to randomly die and take away all your 
backups.
