I particularly do not like the idea of having

way. So I decided to do some tests and see what really was
happening. No issues. Instead I prefer the LVM solution.
The point is to make sure severall disks are being write
at the same time (load balance) and more resiliency since a
dead LVM is a terrible situation.
But I kind of agree with you: I don't know why to use
different Media Types for compatible media.
Because, using the previous example config, volumes in directory
/sdb1/bacula/backup cannot be loaded into vDrive1 and volumes in
directory /bacula/backup cannot be loaded into vDrive2. Bacula uses
the MediaType to decide which volumes can be loaded into which
Devices. A backup job will run without error, writing to either one
directory or the other. But unless tvDrive1 and vDrive2 have
different Media Types, a subsequent restore job will assume it can
load any of those volumes into whichever Device it happens to get
assigned to read from.
