Ben,
CPU is:
model name : Intel(R) Xeon(R) CPU E5540 @ 2.53GHz
We run 4 backup threads and get 4 cores doing 100% each, still we're
only getting the 80 Megabits.
Here's the part of the bacula-fd.conf that is relevant:
FileDaemon {
Name = backup-fd
FDport = 9102
WorkingDirectory = /var/lib/bacula
Pid Directory = /var/run
Maximum Concurrent Jobs = 20
FDAddress = 127.0.0.1
PKI Signatures = Yes
PKI Encryption = Yes
PKI Keypair = "/etc/bacula/keys/bacula-fd.pem"
PKI Master Key = "/etc/bacula/keys/master.cert"
}
Here's an example job spec:
Job {
Name = "ias"
JobDefs = "Standard"
Schedule = "With-Basejobs"
FileSet = "ias"
Accurate = yes
Base = "ias-base"
}
Job {
Name = "ias-base"
Level = Base
JobDefs = "Standard"
FileSet = "ias"
Schedule = "Update-Basejobs"
Accurate = yes
}
FileSet {
Name = "ias"
Include {
Options {
BaseJob = pmugcs5
Accurate = mcs5
Verify = pin5
signature = MD5
compression=GZIP
}
File = /nas/ias
}
Exclude {
File = /nas/exclude
}
}
Storage def from bacula-dir.conf:
Storage {
Name = Tandberg
Address = 127.0.0.1
SDPort = 9103
Password = "e3Ci8AxSF2ewxzX2VgaU"
Device = Tandberg
Autochanger = yes
Media Type = LTO3
Maximum Concurrent Jobs = 20
AllowCompression = yes
}
Devices in bacula-sd.conf:
Autochanger {
Name = Tandberg
Device = IBM0, IBM1
Changer Device = /dev/sg6
Changer Command = "/usr/lib64/bacula/mtx-changer %c %o %S %a %d"
}
Device {
Name = IBM0
Drive Index = 0
Media Type = LTO3
Archive Device = /dev/st0
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
Autochanger = yes;
Maximum Concurrent Jobs = 2
Spool Directory = "/opt/spool/ibm0"
}
Device {
Name = IBM1
Drive Index = 1
Media Type = LTO3
Archive Device = /dev/st1
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
Autochanger = yes;
Maximum Concurrent Jobs = 2
Spool Directory = "/opt/spool/ibm1"
}
Could it be the "compression=GZIP" in the job defs that is slowing
things down?
I really should get my colleague to join this as he's the one that set
this up.
Cheers
Alex
