Hi,
We're experimenting with bacula as possible replacement for our netvault
setup. On the netvault server, we have multiple partitions that we can
use for file-based tapes. (This allows us to easily add arrays / space
in case we need more; something a striped setup would not allow for
instance.)
I can't seem to find out how we can use multiple storage devices with
bacula. The examples in the manual seem to assume that we want to have a
different storage device or pool for different clients, but basically I
just want to use the same pool for all clients, and use whatever storage
is available in a certain pool. (Using a next disk if the previous if
filled.)
I defined multiple devices in my bacula-sd.conf, like so:
Device {
Name = dev1
Media Type = File1
Archive Device = /data/dev1
LabelMedia = yes
Random Access = Yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
}
Device {
Name = dev2
Media Type = File2
Archive Device = /data/dev2
LabelMedia = yes
Random Access = Yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
}
And configured them in bacula-dir.conf:
Storage {
Name = dev1
Address = bacula.wind.surfnet.nl
SDPort = 9103
Password = ...
Device = dev1
Media Type = File1
Maximum Concurrent Jobs = 5
}
Storage {
Name = dev2
Address = bacula.wind.surfnet.nl
SDPort = 9103
Password = ...
Device = dev2
Media Type = File2
Maximum Concurrent Jobs = 5
}
I tried to put these together in a pool, something that apparently
doesn't work ;-)
Pool {
Name = Default
Pool Type = Backup
Label Format = Vol
AutoPrune = yes
Volume Retention = 30d
#Recycle Oldest Volume = yes
#Purge Oldest Volume = yes
Storage = dev1,dev2
Maximum Volume Bytes = 10GB
#Maximum Volumes = 4
}
Still experimenting with toggles there. (Recycle/Purge Oldest Volume
seems interesting in combination with a limited volume size, just to
allow whatever space there is for backups: just the more there is to
backup, the less history we get. I might want to have a different Pool
for Full vs. Incrementals though.)
But it doesn't use dev2 as soon as dev1 is filled for instance (or has 4
volumes, but I guess that might just count for all of the devices.)
Any suggestions on how to use multiple disk-devices for the same pool?
The same pool is no problem at all. What is the problem is bacula
does not normally move a job from one device to a second and it will
never continue a job from one media type to a different. The first
problem can possibly be overcome with what is called as a virtual
autochanger. There is a thread about this here:
