Maybe I'd better have omitted that last sentence (in parenthesis), it now
mislead the point into not-so-essential area. So I'll try to start over:
My primary interest was if I can drop the "virtual autochanger" and one of
the "devices" away from the example (derived from 7.0.5 example confs)
below, without a significant functionality loss in a small environment:
==========================================
# Define a Virtual autochanger
#
Autochanger {
Name = FileChgr1
Device = FileChgr1-Dev1, FileChgr1-Dev2
Changer Command = ""
Changer Device = /dev/null
}
Device {
Name = FileChgr1-Dev1
Media Type = File1
Archive Device = /bdisk1
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 5
}
Device {
Name = FileChgr1-Dev2
Media Type = File1
Archive Device = /bdisk1
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 5
}
==========================================
Which would essentially result in something like this:
(example copied from a very old sd.conf example of Bacula 2.4.0)
#Device {
# Name = FileStorage
# Media Type = File
# Archive Device = /tmp
# LabelMedia = yes; # lets Bacula label unlabeled media
# Random Access = Yes;
# AutomaticMount = yes; # when device opened, read it
# RemovableMedia = no;
# AlwaysOpen = no;
#}
In other words: if the old short (without virtual autochanger) way to
describe the file storage still works as I believe, what is the significant
benefit gained if I define the autochanger?
So I've used a tape autochanger for years and I have a kind of understanding
how to configure it, but what is the idea why to add an autochanger resource
to file storage, without no obvious functionality?
Regards,
Timo
