This makes sens, and it keeps my configuration simple..

As far as configuration then:
1. I should copy my 'default' pool definition and create a new one by adding:

Maximum Volumes = 20
Volume Retention = 365 days
Maximum Volume Bytes = 25 GB
Label Format = 'Volumes'  (should I pick a different name/ format)
(also add label media = yes in a device)

Anything else?

2. Tomorrow if the full backup succeeded how do I get rid of the old
volume so that bacula knows about it and doesn't try to access it
later.

Thanks,
Lucas
