Re: [Bacula-users] backup to multiple disks

I am wondering why and how you come up with ideas
that don't correspond to what Bacula actually does.
It is very unfortunate, because it seems
that this is causing you lots of problems you should not
have.

Every Device resource that is referenced by a virtual Autochanger
resource in bacula-sd.conf is equivalent to a tape drive. The
Volumes that have been created are equivalent to the slots,
you get one slot per Volume -- as many as you want. I don't
think it is a good idea to think about Volumes and Virtual Changers
as having slots, because slots are physical locations for storing
cassettes in a autoloader. With files, you can easily have thousands.

Best regards,
Kern

That's exactly the problem: "virtual autochanger" as described by Kern
automatically selects the first Device and stops there. It doesn't
*change* Devices.

A closer look at Kern's example configuration shows that both of his
Devices refer to the same Archive Device, so what it actually does is
create multiple "Device" definitions for the same physical drive. That's
like a tape robot with several drives and only one tape slot. I'm sure
someone out there might wanna do that, I just fail to imagine why.
