Re: [Bacula-users] Use multiple HDDs to backup files to

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.

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 :-)
