If your backup is growing (they always are), you will eventually hit the 
limits. There are a couple of workarounds: 1. use hot-swappable drives 
and vchanger. That means manual swapping of drives & re-labeling the 
volumes when your storage fills up. Some volumes will be offline. 2. Use 
resizable storage like zfs and hope drive capacity grows faster than 
your backup. Then you can keep replacing your drives w/ bigger ones & 
keep up while keeping everything online. No vchanger means bacula's 
autolabeling will work, too. 3. Back up to "cloud files". This one's 
ugly for many reasons but in theory "the cloud" will accommodate any 
number of file volumes, they'll all be online, autolabeled, etc.
