Hello.
I'm using bacula 5.0.3 since november 2010. Now i'm facing
problem with my backup jobs. We have a mail server that
also runs bacula-fd and i have to backup it, but this
computer has very large file system partitions. Bacula have to backup
about 310 gigabytes of data on full backup. Right now i'm facing problem
that full backup does not fit my Max Run Time which is 42
hours (17280000 seconds). On full backup mail server goes
first and when doing full backup bacula started to terminate
mail server full backup jobs and all other server do not
have their full jobs started. Of course i can lower its priority
and crank Max Run Time to something like 5 days,
but i think it is not right solution for my problem.
And here is my question: how I can parallelize backup jobs execution?
I have following setup: 3 pools for full, differential and
incremental jobs. Maximum concurrent jobs are set to 20 in
bacula-{dir,sd}.conf, but when scheduled jobs are executed
they run consequentially, one starts, then it finishes and
another one is launched for exection. All pool backup
data is stored on NFS share which is the signle device that
is connected to bacula-sd. Why my jobs are not concurrent?
According documentation (26.2 Concurrent Disk Jobs) jobs
could run simultaneously, but in fact it is not. I want bacula
to write simultaneously into one volume, not in separate
volumes. Soon I will add from 5 ti 10 heavy loaded servers with
big filesystems to my current 9 client and I would like to
backup them concurrently.
bacula-dir.conf:
...
director {
name = bacula-dir
dirport = 9101
queryfile = "/usr/lib/bacula/query.sql"
working directory = "/var/lib/bacula"
pid directory = "/var/run"
maximum concurrent jobs = 20
password = "XXXXXX"
messages = Daemon
}
jobdefs {
name = "job defaults"
type = backup
level = incremental
fileset = "Full Set"
schedule = "monthly cycle"
storage = disk-storage
pool = "full pool"
full backup pool = "full pool"
differential backup pool = "diff pool"
incremental backup pool = "incr pool"
priority = 10
write bootstrap = "/var/lib/bacula/%c.bsr"
messages = Standard
# 48 hours
max run time = 1728000
}
schedule {
name = "monthly cycle"
# Full backup on each even month
run = full February,April,June,August,October,December 1st sun at 22:05
run = differential 2nd-5th sun at 22:05
run = incremental mon-sat at 22:05
}
storage {
name = disk-storage
address = 172.20.20.29
sd port = 9103
password = "ХХХ"
device = backup-disk-device
media type = File
}
bacula-sd.conf:
...
storage {
name = bacula-sd
sdport = 9103
working directory = "/var/lib/bacula"
pid directory = "/var/run"
maximum concurrent jobs = 20
heartbeat interval = 30 sec
}
device {
name = backup-disk-device
media type = File
archive device = /var/backup
label media = yes # lets Bacula label unlabeled media
always open = yes
automatic mount = yes # when device opened, read it
random access = yes
removable media = no
}
