I particularly do not like the idea of having separate volumes of the same media type into two different mount points, but I know people that are configuring this 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.

Do you have some specific reason to need to have these two volumes separate?

You might be best off using LVM to create a single logical drive. That
would certainly be a more flexible solution long term.
