Hello Dan,

Heitor is right :)

Thank you.

Ana: what are you using to quickly test these configurations?  I suspect a VM or similar.

I run tests with exactly your configuration and had the same issue. The drive index 0 must exist and belongs to the autochanger resource. You have an Index 0 drive in your configuration: vRestore. But it is not in the Autochanger definition. If you put it there, it will work:

Autochanger {
	Name = VirtualDisk
	Changer Device = /dev/null
	Changer Command = /dev/null
	Device = vRestore, vDrive-1, vDrive-2, vDrive-3, vDrive-4, vDrive-5
	}

I tried defining the vRestore drive with "autoselect = no" (this work for physical autochangers). But it seems to make no sense when dealing with virtual disk autochangers.

Do we need vRestore in there?  Instead, I renumbered my Drive Index fields from zero.

Autochanger {

  Name = VirtualDisk

  Changer Device  = /dev/null

  Changer Command = /dev/null

  Device          = vDrive-1, vDrive-2, vDrive-3, vDrive-4, vDrive-5

}

Device {

  Name           = vDrive-1

  Media Type     = File

  Archive Device = /usr/local/bacula/volumes

  LabelMedia     = yes

  Random Access  = yes

  AutomaticMount = yes

  RemovableMedia = no

  AlwaysOpen     = no

  Autochanger    = yes

  Drive Index    = 0

  Maximum Concurrent Jobs = 1

  Volume Poll Interval    = 15

}

Device {

  Name           = vDrive-2

...same as above

  Autochanger    = yes

  Drive Index    = 1

  Maximum Concurrent Jobs = 1

  Volume Poll Interval    = 15

}

Device {

  Name           = vDrive-3

...same as above

  Autochanger    = yes

  Drive Index    = 2

  Maximum Concurrent Jobs = 1

  Volume Poll Interval    = 15

}

Device {

  Name           = vDrive-4

...same as above

  Autochanger    = yes

  Drive Index    = 3

  Maximum Concurrent Jobs = 1

  Volume Poll Interval    = 15

}

Device {

  Name           = vDrive-5

...same as above

  Autochanger    = yes

  Drive Index    = 4

  Maximum Concurrent Jobs = 25

  Volume Poll Interval    = 15

}

Having a single drive for restores worked for me. I was able to restore files from jobs/volumes that used the autochanger for backup.

 

​​ Device {
	Name = Restore ​-Drive​
	Media Type = File
	Archive Device = /usr/local/bacula/volumes
	LabelMedia = yes
	Random Access = yes
	AutomaticMount = yes
	RemovableMedia = yes
	AlwaysOpen = yes ​​

}

I have this in my bacula-sd.conf:

Device {

  Name           = Restore-Drive

  Media Type     = File

  Archive Device = /usr/local/bacula/volumes

  LabelMedia     = yes

  Random Access  = yes

  AutomaticMount = yes

  RemovableMedia = no

  AlwaysOpen     = no

  Maximum Concurrent Jobs = 1

  Volume Poll Interval    = 15

}

When I run a restore job, it selects vDrive-1 automatically.

How did you get the restore to use Restore-Drive?

Best regards,

Ana

Do not undervalue that.  :)

I'll have a look soon.  Thanks.
