Hello,
Maybe you could use the "virtual autochanger" resource:
This will not work as expected. If the ArchiveDevice in the two
Device resources specifies different directories (mountpoints),
then the two Device resources cannot have the same MediaType. This
is because Bacula expects to be able to load any volume that has
MediaType=File into any Device having that same MediaType, and a
volume in
/sdb1/bacula/backup cannot be loaded into
Device
vDrive-1, not can a volume in
/bacula/backup be loaded into
vDrive-2.
No, volumes in
/sdb1/bacula/backup will not be loaded into
vDrive-1 and volumes in
/bacula/backup will not be loaded into
vDrive-2. I read about this in the white papers from blog.bacula.org
<http://blog.bacula.org>. I decided to do some tests with this. Lots
of people are working with virtual autochangers this way. When you
submit concurrent jobs, the volumes are mounted into their respective
devices. If a requested volume is in
/sdb1/bacula/backup , it will be loaded into
vDrive-1 and if a requested volume is in
/bacula/backup, it will be loaded into
vDrive-2. This works this way and gives no error. But I agree with you
that the option using LVM is a lot better.
Yes. For a backup job using automatic labeling, it will indeed work. But
that is misleading. Say on 1 June a full job ran using vDrive1 and wrote
to volume full_1 in directory /bacula/backup. On 2 June an incremental
job is run, only this time it was assigned vDrive2 and wrote to volume
inc_1 in directory /sdb1/bacula/backup. Both of these jobs will run
without error. However, now a restore is impossible, as is a subsequent
Virtual Full job.
Best regards,
Ana
To use multiple HDDs as a single autochanger, you must:
Define each Device resource to have a unique MediaType, if using
the native virtual autochanger
or
Use vchanger, which is designed for using multiple removable HDDs
(See http://sourceforge.net/projects/vchanger/)
or
Combine the HDD partitions using LVM2 or md so that there is only
a single mountpoint
.
bacula-sd.conf:
Autochanger {
Name = VChanger
Changer Device = /dev/null
Changer Command = "" # versão 5.2.6. For 7.0.5 version, use /dev/null
Device = vDrive-1, vDrive-2
}
Device {
Name = vDrive-1
Drive Index = 0
Device Type = File
Media Type = File
Archive Device = /bacula/backup
...
}
Device {
Name = vDrive-2
Drive Index = 1
Device Type = File
Media Type = File
Archive Device = /sdb1/bacula/backup # is this your mount point?
...
}
In your bacula-dir.conf (or wherever you have your storage
definiton for director):
Storage {
Name = MyVirtualAutochanger
Address = X.X.X.X
SDPort = 9103
Password = "xxxxxxxxxx"
Device = VChanger
Media Type = File
Maximum Concurrent Jobs = XX
Autochanger=yes
}
Best regards,
Ana

I would like to set up bacula - well, my first steps have
been successful.
All my backups are written to /bacula/backup. But / has only
900GB. So I want bacula to write to /sdb1/bacula/backup, too.
/sdb1 has another 950GB of space. The sum of available
backup-space should be 1850GB HDD:
Well, I got the following config of /etc/bacula/bacula-sd.conf:

Okay - now I would like to add another device. I guess I
could just add a second entry like this:

?
Do I have to change something else so that bacula is able to
write more than 900GB - if the first 900GB are "full" it
should switch to the second hdd.
Thank you very much :-)
