Oh, messing up configurations is always a fun thing... when it happens
to others ;-)

Use different Media Types as MasterBrian suggested. You'll probably also
have to manually update the catalog to reflect the changes if you want
to keep your existing volumes.

I don't see why that wouldn't work.

Two possibilities: Enable automatic labeling - just don't use a label
format that includes the date, job name, or anything that changes
between backup jobs as that only confuses you later because it will not
represent the actual volume contents. My opinion, of course. Limit the
number of volumes per pool. Then, whenever you add more storage devices,
you only have to copy the device definition and the corresponding
volume(s) will be created automatically.
Or pre-create volumes per device as needed, which is more work for you,
but if you don't create storage devices daily that's not really bad.

I don't understand the problem... you mean that the Storage= line in the
job causes errors? Astonishing, since that storage device is declared in
the DIR unless I overlooked a misspelling or something.

No and yes. You have to declare each storage device you want to use in
the DIR, but the SD always reports all storage devices it handles.

It usually does... but you must ensure that Bacula always uses the
correct device for each volume. This is where the Media Type is
important, otherwise Bacula will want to access volumes in another
device than they belong to. That mostly happens when restoring.

Nothing new from me...
