>> Assunto: [Bacula-users] Virtual Autochanger
> 
>> Dear all,
>> 
>> We recently bought two identical HP Ultrium 448i tape drives.  We want
>> to use them with Bacula and found the white paper "Best Practices for
>> Disk Backup" [1] that describes how to configure a virtual autochanger.
>> We applied the necessary changes in order to model our two drives
>> combined in one virtual autochanger and tried it with a backup job that
>> needs more than one tape.
>> 
>> Bacula used the first tape as expected but when in came to use the
>> second tape it requested the second tape to be mounted in the first
>> drive although the tape was correctly mounted in the second drive.
>> 
>> Now I would like to ask the experts if it is possible to make a setup
>> like I described work and if so, what we did wrong so far.  We are
>> currently using bacula 5.2.6 from Debian stable (8.0 aka jessie).  So
>> far we have been using bacula with one drive for the past 10 years or so
>> and did not have any problems.
>> 
>> Here are the relevant portions of our configs:
>> 
>> <bacula-dir.conf>

>>  Device = Virtual
>>  Media Type = Ultrium2
>>  Autochanger = yes
>> }
>> 
>> JobDefs {
>>  Name = "DefaultJob"
>>  Type = Backup
>>  Client = hamster-file
