I use bacula 2.4.2 (from debian backports) together with a Iomega
removable hard disk system. After some experimenting I use the following
SD configuration:
Storage {
Name = lexington-sd
WorkingDirectory = "/var/lib/bacula"
Pid Directory = "/var/run/bacula"
Maximum Concurrent Jobs = 10
SDAddresses = {
ip = { addr = 127.0.0.1 }
ip = { addr = lexington }
}
}
Director {
Name = lexington-dir
Password = "guess"
}
Device {
Name = IOMEGA-REV-DISK
Archive Device = /media/iomega-rev-disk
Device Type = File
Media Type = REV-120GB
Volume Poll Interval = 2 minutes
Removable Media = yes
Random Access = yes
Requires Mount = yes
Mount Point = /media/iomega-rev-disk
Mount Command = "/bin/mount /media/iomega-rev-disk"
Unmount Command = "/bin/umount /media/iomega-rev-disk"
}
Messages {
Name = Standard
director = lexington-dir = all
}
In /etc/fstab I do have the following entry:
/dev/scd0 /media/iomega-rev-disk ext3 defaults,noauto,acl 0 2
First of all: way do I have to set 'Archive Device' to the mount point
instead of the device? If I use the device the SD (in debug mode)
complains about not being able to create a file on '/dev/scd0' which is
ok. The file should be created by the SD on /media/iomega-rev-disk'
instead. If 'Archive Device' is set correctly like this, what is the
'Mount Point' option for?
In fact the configuration above does not really work. It sometimes does
when I run the SD with '-d100'. My Idea of what the configuration above
should do is: automatically try to mount a removable hard disk found in
device '/dev/scd0' to '/media/iomega-rev-disk' when required. However
this does not happen. Bacula complains that I should mount the device;
entering the command 'mount' in the bacula console returns without error
but nothing more happens. From the Linux console I can see that
'/dev/scd0' is not mounted. Mounting it manually, returning to the
bacula console and again issuing the 'mount' command does not change
anything; bacula will still ask me to mount a media.
What kind of problem do I have here with device, media, mount point and
the mount command itself? Is it perhaps wrong to use 'File' as 'Device
Type' with my hardware?
If things would work I would also like to use 'Always Open = No' to tell
bacula to unmount (not eject!) the disk after backup. Sadly the
documentation says 'For File storage, this directive is ignored'.
I know about the possibility to run commands before and after jobs but I
think this would definitely be the wrong place for SD management.
