The volumes are tied to a pool. You would have Volume001 in the first
storage location and Volume002 in the second storage location. E.g.
disk
+--- client1
| +--- Volume001
+--- client2
+--- Volume002
All depending on your schedule, naturally.
When you want to backup every client to his own storage location (or set
of media), you have to have a pool and a storage device for each client.
I recommend to work with include files in this case. I use a separate
file for each client and include them in bacula-dir.conf.
At the end of bacula-dir.conf i have
@/path/to/conf/clients/Catalog
@/path/to/conf/clients/client1
@/path/to/conf/clients/client2
@/path/to/conf/clients/client3
..
And each client file looks basically like
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
# http://localhost/opkg/doc/bacula/bacula/Configuring_Director.html
Client {
Name = @[EMAIL PROTECTED]
Address = @[EMAIL PROTECTED]
FDPort = 9102
Catalog = DefaultCatalog
Password = "@[EMAIL PROTECTED]" # pwd FileDaemon
File Retention = 60 days
Job Retention = 6 months
AutoPrune = yes # Remove expired File-/Jobinfos from Database
}
#
# ---------------------------------- STORAGE ----------------------------------
#
#
# Access devices from the Storage Daemon.
# Name and MediaType here and in the Storage Daemon's "Device"
# entry must be identical.
#
Storage {

Media Type = [EMAIL PROTECTED]@
}
#
# ----------------------------------- POOLS -----------------------------------

Accept Any Volume = yes # use next available volume
Maximum Volume Jobs = 6 # whole week in one volume/file

#
# ------------------------------- FILESETS ------------------------------------

}
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
The file for the Catalog looks like this:
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
#
# Generic catalog service
#
Catalog {
Name = DefaultCatalog
dbname = bacula; user = bacula; password = ""
}
#
# ---------------------------------- STORAGE ----------------------------------
#
#
# Access devices from the Storage Daemon.
# Name and MediaType here and in the Storage Daemon's "Device"
# entry must be identical.
#
Storage {
Name = FIXDISK-Catalog
Address = @[EMAIL PROTECTED]
SDPort = 9103
Password = "@[EMAIL PROTECTED]"
Device = FIXDISK-Catalog
Media Type = File-Catalog
}
#
# ----------------------------------- POOLS -----------------------------------
#
#
# Default pool definition (FIXEDDISK)
#
Pool {
Name = full-Catalog # used daily
Pool Type = Backup
Label Format = "0.full.${Job}.${NumVols:p/2/0/r}"
Accept Any Volume = yes # use next available volume
Maximum Volume Jobs = 1
Maximum Volumes = 10
Volume Retention = 9 days # catalog entries
AutoPrune = yes # Prune expired volumes
Recycle = yes # automatically recycle Volumes
}
#
# ------------------------------- FILESETS ------------------------------------
#
# This is the backup of the catalog
FileSet {
Name = Catalog
Include {
Options {
signature = MD5
compression = GZIP9
}
File = /opkg/var/bacula/bacula.sql
}
}
#
# -------------------------------- BACKUP JOBS --------------------------------
#
#
# Backup the catalog database (after the nightly save)
#
Job {
Name = Catalog-disk
Client = @[EMAIL PROTECTED] # where the director runs/the db resides
JobDefs = DefaultJob
Storage = FIXDISK-Catalog
FileSet = Catalog
Level = Full
Schedule = WeeklyCycleAfterBackup
Pool = full-Catalog
# This creates an ASCII copy of the catalog
RunBeforeJob = "/opkg/libexec/bacula/make_catalog_backup bacula bacula"
# This deletes the copy of the catalog
RunAfterJob = "/opkg/libexec/bacula/delete_catalog_backup"
Write Bootstrap = "/opkg/var/bacula/Catalog-disk.bsr"
Priority = 11 # run after main backup
}
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
And for the Catalog and each client there is a storage device. At the end
of bacula-sd.conf i have:
@/path/to/conf/clients/Catalog-sd
@/path/to/conf/clients/client1-sd
@/path/to/conf/clients/client2-sd
@/path/to/conf/clients/client3-sd
..
And each file looks like:
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
Device {
Name = [EMAIL PROTECTED]@
Media Type = [EMAIL PROTECTED]@
Archive Device = /backup/bacula/fixdisk/@client@
AlwaysOpen = no
RemovableMedia = no
Random Access = yes
RequiresMount = no
LabelMedia = yes # lets Bacula label unlabeled media
AutomaticMount = yes # when device opened, read it
}
---------8<---------8<---------8<---------8<---------8<---------8<---------8<
Where "@client@" can be "Catalog".
Well, i'm running this for less than a month - maybe i have to play a bit
with the retention timings.
