Re: [Bacula-users] Disk setup for best performance on backups

[Jason Voorhees]

Sorry for the late reply guys, I've been busy these last days.

I really appreciate all the responses you made to this thread. I'll
read carefully all of them and take into consideration for my
deployment.

Hope you all have a nice weekend!

[Bacula-users] Disk setup for best performance on backups

[Jason Voorhees]

Hello guys:

I'm planning a Bacula deployment on AWS in the following weeks. I have
some doubts about disk performance for Disk based backups.

Based on the idea that Bacula writes data on big files (i.e. 100 GB
each volume), what technical considerations should I have for the
underlying storage device? These are some of my questions I have
around it:

- Does it matter a lot choosing XFS instead of ext4 as filesystem?
- How can I know the amount of IOPS needed for my local disk?
- What does Bacula need most: high IOPS or throughput (MB/s)?
- Based on the previous question, should I choose SSD over HDD disks?
- Is it worth using RAID1 or RAID10 for improving performance?

I was planning to use HDD disks which offers high throughput (500
MB/s) and up to 500 IOPS per disk (these are "st1" EBS volumes).

By the way, I pretend to use an external DB (Amazon RDS) for my
Catalog, so my Storage daemon wouldn't share the same underlying
storage.

I hope someone can share some ideas about disk performance.

I didn't find enough info about this topic on Internet. Thanks in advance

Re: [Bacula-users] Backups to S3

[Jason Voorhees]

You're right, I completely forgot about costs. Definitely, using S3
plugin will be much more cheaper than using Amazon Storage Gateway
VTL.

On my scenario, Cloud (S3) is the only place where I could save my
backups, but I fully understand the comparison you made about your on
premises environment.

Thank you all guys

That's exactly what I wanted to know... if this Cloud/S3 plugin is not
just good, but it's also reliable enough for using it on production
servers

I'll start playing around with it. I'll let you know if anything does
not work as expected.

[Bacula-users] Backups to S3

[Jason Voorhees]

Hello guys, I hope you're doing well

I have a question: So far, which is the best combination for storing
backups on S3 using Bacula? Is it through the new Cloud plugin? or is
it best to use the Amazon VTL integration with Bacula? Which of these
is the more reliable for production environments? Which one would you
use?

My scenario seems to be simple enough: I need to backup data from
several EC2 instances using Bacula and Amazon S3, both (EC2 and S3) in
the same region. So bandwidth and data transfer pricing wouldn't be an
issue for me.

I hope someone can share his experiences and/or recommendations.

Thanks in advance for your help, bats!

[Bacula-users] Bacula largest installations ever

[Jason Voorhees]

Hello bats:

I was wondering if you can share any of your biggest Bacula
deployments you ever made. I mean anything like "I use Bacula to
backup thousands of desktops/servers", or "I have a backup
infrastructure with Bacula for more than 30TB of data being backed
up".

It's just that I want to know how robust and scalable Bacula might be
compared to other competitors such as TSM, HP Dataprotector, Backup
Exec, among others.

This is because one of my customer want to backup more than 2,000
desktops and a backup software is under evaluation.

Thanks in advance for your comments, if any.

Re: [Bacula-users] Bacula in the cloud

[Jason Voorhees]

Thank you all for your responses.

I'll take a look at Bacula systems' whitepaper to see what they're
talking about. Meanwhile I'll explore some of the alternatives
discussed on this thread like copying files with scripts and making a
replica on SpiderOak or anything similar.

I hope we can have an interesting solution for this "problem" in the
near future.

Thanks again for your time :)

[Bacula-users] Bacula in the cloud

[Jason Voorhees]

Hello guys:

Based on your experience, what alternative do we have for backing up
information to the cloud preferably using Bacula?

I've been reading some posts about similar topics. Bandwidth always
seem to be a problem because it isn't to big (Gigs per second) or
there's to much information (several terabytes) and Bacula can't run
jobs for so long without modifying source code and recompiling.

I've been thinking something alternatives like these:

1. Backup to local disk and configure Copy jobs to make a copy to
Amazon S3. Local backups can run always fast but Copy jobs might be
delayed ... without issues?

2. Configure Amazon Storage Gateway as VTL so Bacula can backup
directly to Amazon using virtual tape devices through iSCSI. What do
you think about this?

3. For a single fileserver to be backed up (let's say a Samba server),
I could create a replica in the cloud (i.e. Amazon EC2) which can be
constantly synchronized (via rsync) and run Bacula locally in such EC2
instance.

What other ideas have you thought? Maybe a combination of other open
source tools that can be combined with Bacula? or maybe a different
open source solution that replaces Bacula to save backups in the
cloud?

I'd appreciate some ideas, pros and/or cons to be discussed.

Thanks in advance for your time bats!

[Bacula-users] Best backup strategy on short disk capacity

[Jason Voorhees]

Hello guys:

I'm running Bacula 7.4.0 to save backup of my Windows fileserver which
has 4 drives (D:, F:, G:, H:) with 7.1 TB of total capacity.

I've ran a full backup during 7 days which occupied 5.8 TB (~20%
compression rate) in a local filesystem with local SATA disks. This
local filesystem is at 80% usage so I don't have enough free space to
run a 2nd full backup. I was planning to run Full + Incremental +
Differential backups like this:

- Full -> 1st sunday
- Differential -> 2nd-5th sunday
- Incremental -> monday-saturday

If my full backup takes 7 days to complete, how should I schedule my
jobs? I created 3 Storage resources which each point to 3 different
directories so I can run a Full+Incremental or Full+Differential jobs
concurrently.

Also, how long should my retention periods should be so I can run a
new full backup without filling my disk up to 100%? I thought my
retention period could be something like 30 days or less (maybe 21
days)... but  if my last full backup is overwritten by the new
full backup I guess I won't be able to have a valid copy during the
time my new full backup is running (7 days approximately). Am I right?

I hope you can understand how confused I am here.

P.D. I only use bacula to make backups to this Windows fileserver and
the Bacula server, no more clients are backed up.

Thanks in advance for your help.

oh that makes a big difference. I thought "operatorcommand" was used
exclusively only to notify operators on "mount" events but I wasn't
aware when those messages were sent.

Thanks Kern. What seems strange to me is that the same Messages
resource configuration is working well in a couple of different Bacula
servers (different customers) and I get such kind of messages
inmediately (never delayed).

I've modified the default Messages resource to disable the bsmtp
command in favor of my native mail command which it's currently
routing mail through my postfix service without any issues. Also, the
"all" rule already includes the "mount" operation so messages should
have arrived without delays. I can't understand what went wrong just
that day.

[Bacula-users] Mail notifications delayed

[Jason Voorhees]

Hello guys:

I'm running Bacula  7.4.0 with a Messages resource like this:

Messages {
  Name = Standard
  mail = myem...@gmail.com = all, !info, !skipped, !restored, !saved
  console = all, !skipped, !saved
  append = "/var/log/bacula/bacula.log" = all, !skipped
  catalog = all
}

I've just got today a message with repeated lines like these:

10-Jun 07:06 storage-sd JobId 188: Job
storage_job-dataconf.2016-06-05_00.00.00_30 is waiting. Cannot find
any appendable volumes.
Please use the "label" command to create a new Volume for:
Storage:  "DevFile1" (/var/bacula/file1)
Pool: Full
Media type:   DiskFile1


This was caused because I didn't plan correctly the retention time and
max number of volumes on my "Full" pool. That's pretty fine.

But what concerns  me is that a Full backup was run on 1st Sunday this
month (June 5), but the message mentions "10-Jun" in the date colum.

So what I see is that this email should have arrived inmediately on
June 5 when the Full backup was out of volumes but the message arrived
just today. In my Bacula logs I can see that the same error appears
from June 5, so I have no idea why Bacula didn't send the message on
the right time (10 days ago!!!).

I've checked my postfix logs and there's no trace of emails sent to
myem...@gmail.com on June 5 or June 10. There are just logs of emails
sent to myem...@gmail.com today at 2:00 pm.

Does anybody have any idea why Bacula has delayed the notification for so long?

I'd appreciate some help. Thanks in advance guys.

Hola Enrique:

La lista es de idioma inglés, dudo que consultando en español te respondan.

Sobre tu consulta, si no tienes Internet, ¿cómo obtendrás el RPM? No
recuerdo si Bacula viene en los DVDs de CentOS 6 pero al menos hoy lo
pude instalar usando YUM desde Internet sin usar ningún repositorio
adicional como EPEL (por ejemplo), así que podría suponer que sí viene
en los DVDs.

Sin embargo, la versión es muy antigua (la 5.0.0). ¿No te hace mejor
obtener el tarball de bacula 7.4.0 y compilarlo instalando las
dependencias RPM desde DVD?


Please try to translate your email from Spanish to English so you can
get some help from other english speakers guys.

[Bacula-users] Are my Bacula backups fast enough?

[Jason Voorhees]

Hello guys:

I'd like you to share some thoughs about my scenario and performance.
Here's what I have:

Server (Director & Storage)

System: KVM guest running on Proxmox 4.1 host
Network: virtio
Storage: 5x200 GB Virtual disks (qcow2 format), used as physical volumes
Filesystem: ext4 'by default' on LVM
Memory: 4 GB
CPU: 1 core on guest, 8 cores on host (Intel Core i7 3.4 GHz)
Bacula: 7.4.0 built from source
OS: CentOS 7 x86_64
Roles: Bacula with MySQL (used only for backups, nothing else)



- iperf tests between my bacula server and one of my clients (which is
also a KVM guest sharing the same physical host with virtio network)
gave me near 9.78 Gbps rate which seems awesome.
- I'm using disk backups without Attribute Spooling enabled, yet.
- GZIP compression and SHA1 signatures are also enabled for all my jobs.
- MySQL hasn't been tuned at all, it came by default.


Yesterday, I ran a Full backup for a Samba fileserver with 280 GB of
data. Such backup took about 6 hours, having near 15% compression rate
and near 240 GB written by SD and FD daemons. This Samba server have
Bacula Client 2.4.4.

Today I'm running a Full backup for a Zimbra server with near 450 GB
of data to be backed up. I'm running iptraf-ng right now and I can see
variable rate transfer through my network interface from 10 Mbps up to
80 Mbps with an average of 50 Mbps.

I'd like to hear some thoughts from you because I have some questions:

- Is it normal to have a rate of 50 Mbps rate while running a backup?
- How can I know if MySQL is a bottleneck?
- Should I disable compression and signatures to improve speed of
backups? Is it worth it?
- What if I enable attribute spooling? I've read posts in which some
people noticed an improvement on data transfer but the despooling
process of attributes it took too long.
- Is my backup speed good enough? Should I worry about it? Can they be
even faster?

Thanks in advance for reading and helping :)

Have a nice day

Thank you Kern.

Yes, I have tried that but there's no Makefile in tray-monitor
directory so I can't run make under this path :( I'd like to build it
manually using gcc + arguments but I have no idea how to do it.

[Bacula-users] How to build tray-monitor

[Jason Voorhees]

Hello guys:

I've built Bacula 7.4.0 but I have no idea how to build the
tray-monitor application. I can't find any arguments in ./configure
--help to achieve it even when I found a tray-monitor directory in the
contents of the tarball.

Hope someone can give me some ideas.

Thanks in advance.

Re: [Bacula-users] Difference between Full and Used status

[Jason Voorhees]

Cool, thanks again Kern!

I believe Bacula documentation needs to be reviewed and updated 'cause
there are some typos, outdated and wrong info. I would be happy to help
with this once I finish clarifying some basic concepts about Bacula that I
didn't understand well in the past and caused me some headaches
(filesystems getting full, failed backups, many failed jobs, volumes in
Error status, jobs being upgraded to Full, data not being able to be
restored, paing and suffering, etc...)

Re: [Bacula-users] Difference between Full and Used status

[Jason Voorhees]

Thank you Kern, Phil.

It's pretty clear to me what a Used status means: when a volume reaches its
maximum duration time (i.e. Use Volume Once, Volume Use Duration). But it
wasn't clear the difference with Full status.

If using tapes I could guess that a volume may have a Full status when the
physical media is actually full (i.e. 1.5 TB for a LTO-5 tape), but what
about File volumes? If I use "Maximum Volume Bytes = 10G", will my volumes
get the Full status when they reach 10 GB of data?

Nevermind, I've already solved this. It was due to permissions issue
on /etc/bacula/bconsole.conf not being readable by "tape" group.

Thanks anyway guys :)

[Bacula-users] vchanger not doing "label barcodes" correctly

[Jason Voorhees]

Hello Guys:

This is my first time trying to configure vchanger with Bacula 5.2.13.

I've configured Bacula and vchanger according to the official vchanger
1.0.1 documentation included in source code (vchangerHowto.html).

As per vchanger howto I'm supposed to initialize my magazine by
creating a few volumes by running:

# vchanger /etc/vchanger/vchanger-1.conf createvols 0 3

While it's true that empty volumes are created under the mount point
of my USB disk, they don't get labeled on Bacula. However if I run
"label barcodes" manually from bconsole I'm able to label them without
issues.

The only thing I can "see" is this strange message in vchanger's log file:

mar 13 21:58:01: bconsole: exited with rc=1
mar 13 21:58:01: WARNING! 'update slots' needed in bconsole
mar 13 21:58:01: bconsole: exited with rc=1
mar 13 21:58:01: WARNING! 'label barcodes' needed in bconsole

It seems that after vchanger commands creates the volumes it is unable
to label them through bconsole due to an unknown error. I tried to use
"bconsole = /usr/sbin/bconsole -d 200" in vchanger-1.conf but I can't
get any extra info or verbose messages about the error.

Here's some of my most important configuration:

# /etc/vchanger/vchanger-1.conf
mar 13 21:58:01: bconsole: exited with rc=1
mar 13 21:58:01: WARNING! 'update slots' needed in bconsole
mar 13 21:58:01: bconsole: exited with rc=1
mar 13 21:58:01: WARNING! 'label barcodes' needed in bconsole


# /etc/bacula/bacula-sd.conf
Autochanger {
Name = usb-vchanger-1
Device = usb-vchanger-1-drive-0, usb-vchanger-1-drive-1
Changer Command = "/usr/local/bin/vchanger %c %o %S %a %d"
Changer Device = "/etc/vchanger/vchanger-1.conf"
}

Device {
Name = usb-vchanger-1-drive-0
Drive Index = 0
Autochanger = yes
Device Type = File
Media Type = File
Removable Media = no
Random Access = yes
Maximum Concurrent Jobs = 1
Archive Device = /var/spool/vchanger/vchanger-1/0
}

Device {
Name = usb-vchanger-1-drive-1
Drive Index = 1
Autochanger = yes
Device Type = File
Media Type = File
Removable Media = no
Random Access = yes
Maximum Concurrent Jobs = 1
Archive Device = /var/spool/vchanger/vchanger-1/1
}

# /etc/bacula/bacula-dir.conf
Storage {
  Name = vchanger-1
  Address = 192.168.1.220
  SDPort = 9103
  Password = 96ba74caf2a7379fd81db4b6e7b82985bafc0aaa
  Device = usb-vchanger-1
  Media Type = File
  Autochanger = yes
  Maximum Concurrent Jobs = 20
}

Hope someone can help me or point me to some place where I can find a
possible solution.

Thanks in advance.

[Bacula-users] systemd file for bacula-dir

[Jason Voorhees]

Hello guys, hope you're doing good:

I'd recently installed bacula 7.4.0 on CentOS 7 x86_64. I don't have
much experience with systemd files but I'm learning through this
process.

I didn't find any bacula*.service files under /usr/lib/systemd/system
directory so I created these ones:

-
bacula-fd.service (it works fine)
-
[Unit]
Description=Bacula File Daemon service

I first tried it with "User" and "Group" directives enabled using
"bacula" user, then I modified to run it as root but using "-u" and
"-g" options as shown above.

The problem I have is that bacula-dir seems to start fine for some
seconds by running:

# systemctl start bacula-dir

... which keeps my prompt waiting for a response, but after some time
the command fails and this appear on my logs:

Feb 21 22:08:13 storage systemd: bacula-dir.service start operation
timed out. Terminating.

Am I missing anything?

Thank you

Is there a way to know which volumes (tapes) will be required by

Hi:

2011/5/16 Kleber Leal kleber.l...@gmail.com:
 The volumes will be showed when you execute restore command.

 Kleber


Yes, you're right. I don't use bconsole to restore jobs but Bat
(GUI). I didn't note that in the Console section I can see which
volumes will be used before clicking OK to begin the restore job.

Thanks, bye.

 My Bacula installation is working perfectly, but when I run bat

 seems to work fine, it loads correctly. I can use without problems the
 Console, Clients, FileSets, Jobs, Pools, Media and

 to hung (similar to suspend a task from shell with ^Z).

 I experienced this on a similar  system with RHEL 6 and I solved just
 installing the hole X Window System and GNOME environment running then
 to runlevel 5. But now I don't want to install the hole GUI of my
 CentOS to solve this.

 Does anybody know why is this hapenning to bat? I hope someone can help me.

 Thanks, bye.

My Bacula installation is working perfectly, but when I run bat
through a ssh x11 forwarding session from my Ubuntu desktop then Bat
seems to work fine, it loads correctly. I can use without problems the
Console, Clients, FileSets, Jobs, Pools, Media and
Storage sections, but Jobs Run, Version Browser and Director
Status don't seem to work. When I click on them the window just seem
to hung (similar to suspend a task from shell with ^Z).

I experienced this on a similar  system with RHEL 6 and I solved just
installing the hole X Window System and GNOME environment running then
to runlevel 5. But now I don't want to install the hole GUI of my
CentOS to solve this.

Does anybody know why is this hapenning to bat? I hope someone can help me.

Thanks, bye.

[Bacula-users] Speed of backups

[Jason Voorhees]

Hi:

I'm running Bacula 5.0.3 in RHEL 6.0 x86_64 with a Library tape IBM
TS3100 with hardware compression enabled and software (Bacula)
compression disabled, using LTO-5 tapes. I have a Gigabit Ethernet
network and iperf tests report me a bandwidth of 112 MB/s.

I'm not using any spooling configuration and I'm running concurrent
jobs, just only one. This is the configuration of my fileset:

FileSet {
   Name = fset-qsrpsfs1
   Include {
   File = /etc
   File = /root
   File = /var/spool/cron
   File = /var/run/utmp
   File = /var/log
   File = /data
   Options {
   signature=SHA1
   #compression=GZIP
   }
   }
}

My backups were running with a minimum of 54 MB/s and a maximum of 79
MB/s. Are these speeds normal for my scenario? What could be the best
speed I could achieve with an optimal Bacula configuration considering
that the network isn't loaded at the time that backups always run? I'm
concerned the difference of speeds between the maximal supported by my
network (112 MB/s) versus the speed of my backups (54 ~ 79 MB/s).

I hope someone can give me some advices to enhance the performance of
my backups.

Thanks

 Is the source a raid? Do you have many small files?

No, there are just a normal number of files from a shared folder of
my fileserver with spreadsheets, documents, images, PDFs, just
information of final users.

 The performance problem is probably filesystem performance. A single
 hard drive will only hit 100 MB/s if you are baking up files that are
 a few hundred MB.

How could I run some tests to verify this? I'm running MySQL server in
the same host where Bacula is installed. My server is a IBM Blade HS
with a local RAID 1.

Hi:

How can I know where's the bottleneck? I'm using an ext4 filesystem.
Are these tests useful?

[root@qsrpsbk1 ~]# hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:  370 MB in  3.01 seconds = 122.89 MB/sec
[root@qsrpsbk1 ~]# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3770 MB in  2.00 seconds = 1885.16 MB/sec
 Timing buffered disk reads:  370 MB in  3.00 seconds = 123.20 MB/sec

First I disabled 'signature=SHA1' at my Jobs and I gained little speed
of my backup (between 79 and 83 MB/s). Then I enabled Data Spooling
(so attribute spooling also is enabled) and my backups became slower
(between 36 and 45 MB/s).

All my tests were done running Full backups. The first large backups
were done without spooling and 4 TB of data, but my recent backups
were done with spooling enabled and 8 GB of data.

Would I need to modify settings of Buffer size in my Storage Daemon?
Is there any other reason for my slow backups? Are my backups really
slow or this speed is normal/good?

 Your benchmark does not measure random or small file performance
 (smaller than a few MB). Any mechanical hard drive will not have  100
 MB/s for this. SSDs or raid will but not a regular hard drive.

 John


So do you believe these speeds of my backups are normal? I though my
Library tape with LTO-5 tapes could write at 140 MB/s approx. It isn't
possible to achieve higher speeds?

I recently made an additional test modify the buffer size setting of
my storage daemon like this:

 Maximum Network Buffer Size = 262144 #65536
 Maximum block size = 262144

With these settings, signature=SHA1 disabled, data  attribute
spooling enabled and bacula software compression disabled I'm still
geting slow speeds.
I don't understand why the speed is so variable in each test I run. My
speed keeps being different each time with 32, 36, 45, 54, 67, ..., 80
MB/s when the backup Job is always the same (8 GB of data).

I'm looking at the speed of backups from the final report of the logs like:

 You need to speed up your source filesystem to achieve better
 performance. Use raid10 or get a SSD. It has nothing at all to do with
 your tape or bacula speed if you hard drive can not read what it needs
 to backup at the maximum network speed. Or do not worry so much how
 much time a single backup is taking and enable concurrency and
 spooling. These will better utilize  the speed of your tape drive.


 John


strange!, I ran a hdparm test at the fileserver (the source of backup)
and I get a better performance:

[root@qsrpsfs1 ~]# hdparm -t /dev/mapper/mpath0

/dev/mapper/mpath0:
 Timing buffered disk reads:  622 MB in  3.00 seconds = 207.20 MB/sec

 That is a raid. But you still may not be able to sustain over 100MB/s
 of somewhat random reads. Remember that hdparm is only measuring
 sequential performance of large reads.


 If it is a raid I cold be wrong about the filesystem performance being
 the only problem. You can test if this is the case by creating a
 backup of a single file that is 1GB or so to media that is already
 loaded and see if the performance is closer to the network maximum.
 Maybe test an already compressed file of this size versus a file
 containing all zeros.

 John


I tried to copy a 10 GB file between both servers (Bacula and
Fileserver) with scp and I got a 48 MB/s speed transfer. Is this why
my backups are always near to that speed?

Re: [Bacula-users] Speed of backups

[Jason Voorhees]

 to get the maximum speed with your LTO-5 drive you should enable data
 spooling and change the Maximum File Size parameter. The spool disk
 must be a fast one, especially if you want to run concurrent jobs.
 Forget hdparm as benchmark, use bonnie++, tiobench, iozone.

 Then after after you have enabled spooling, restarted the SD, start
 the backup. Look at the log file for Despooling elapsed time. This
 will show you how fast the spool file can be written to tape.

 The backup time will increase overall because the data will first be
 written to disk and then to tape, but at least you eliminate the
 network and the data source (server) as bottleneck.

 With spooling enabled and LTO-4 drives I get up 100 - 140 MB/s.

 Ralf


Hi, thanks for your help.

I think I was confusing some terms. The speed I reported was the total
elapsed time that my backup took. But now according to your comments I
got this from my logs:

With spooling enabled:

- Job write elapsed time: 102 MB/s average
- Despooling elapsed time: 84 MB/s average


Without spooling enabled:

- Job write elapsed time: 68 MB/s average

These are averages obtained from a group of 5 or more jobs of each
case (with and without spooling). So I can see that with spooling
enabled the process of writing to tape get higher speeds than
copy-from-fd/write-to-tape without spooling enabled.

Now the question is, why am I getting so low despooling speeds if I
use LTO-5 tapes? Shouldn't I have higher speeds than you with LTO-4
tapes?

I think the write speed of my tape it isn't the best. Some of my tests
(all with spooling enabled) were done with Buffer  Block size
settings at my storage daemon, but other tests were done without those
settings, so I didn't see any appreciable enhancement of performance
changing the value of block sizes.

What can I do?

Re: [Bacula-users] Speed of backups

[Jason Voorhees]

 I got the biggest gain by changing Maximum File Size to 5 GB. How
 fast is the disk where you spool file is locatet?


Ok, I don't have that setting enabled but I could try it. Question:
how do you decide 5 GB is an optimal value for your LTO-4 tapes? what
value could I put for my LTO-5 tapes? I don't really understand what
should be the appropiate value for this directive.
I don't know how to tell you how speed is my local disk (spool
directory), but is this useful?


[root@qsrpsbk1 ~]# hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:  370 MB in  3.01 seconds = 123.00 MB/sec


 A different test would be to create a 10 GB file with data from
 /dev/urandom in the spool directory and the write this file to tape
 (eg. nst0). Note: this will overwrite your existing data on tape and
 you might have to release the drive in bacula.

 dd if=/spoolfile-directory/testfile of=/dev/nst0 bs=xxxk (your bacula block 
 size)

It will take some time to run this test because of the low speed of
/dev/unrandom but I'll show you the results on my next message.

By the way, do I really need to change the buffer/block size at the
Storage configuration? What buffer/block size should I use?

Ok, I made this:

[root@qsrpsbk1 spool]# dd if=random.tst of=/dev/st0 bs=2048k count=5000
5000+0 records in
5000+0 records out
1048576 bytes (10 GB) copied, 160.232 s, 65.4 MB/s

The block size of 2048k is the same I'm using at Bacula Storage Daemon
configuration (Maximum Block Size = 2097152). Why the speed of dd was
65 MB/s when my Despooling speed is about ~80-90 MB/s?

Well, these are my results of a bonnie++ test:

[Bacula-users] About tapes capacity

[Jason Voorhees]

Hi people:

I'm running Bacula 5.0.3 with an tape library IBM TS3100 using LTO5
tapes of 1.5 TB capacity each one. I have a simple question: If I run
a job backup of a server that holds more than 1.5 TB (example: 2 TB of
data), what happen when Bacula reaches the limit of the tape capacity?
Does Bacula automatically change the tape?

I'm not pretty sure about this because I recently ran a job backup of
2 TB and Bacula apparently just used one tape: have a look at my
volume listing:

* list volume
...
...
|   5 | L5BA0005   | Append|   1 | 2,058,019,117,056 |
2,059 |2,160,000 |   1 |5 | 1 | LTO-5 |
2011-04-19 20:58:51 |
+-++---+-+---+--+--+-+--+---+---+-+

When the job started Bacula took the tape L5BA0005 and never required
another one. As you can see Bacula apparently wrote 2,058,019,117,056
bytes (approx. 2 TB) but my tape is just 1.5 TB capacity. Does anybody
know why? My job isn't using compression so I really don't understand
this.
Just for additional information there are a lot of new tapes on my
magazines. Have a look at this:

So I don't know why Bacula didn't take a free tape of Scratch pool. I
hope someone can help me to understand this Bacula behavior.

Thanks, bye.

 Hi people:

 I'm running Bacula 5.0.3 with an tape library IBM TS3100 using LTO5
 tapes of 1.5 TB capacity each one. I have a simple question: If I run
 a job backup of a server that holds more than 1.5 TB (example: 2 TB of
 data), what happen when Bacula reaches the limit of the tape capacity?
 Does Bacula automatically change the tape?

 I'm not pretty sure about this because I recently ran a job backup of
 2 TB and Bacula apparently just used one tape: have a look at my
 volume listing:

 * list volume
 ...
 ...
 |       5 | L5BA0005   | Append    |       1 | 2,058,019,117,056 |
 2,059 |    2,160,000 |       1 |    5 |         1 | LTO-5     |
 2011-04-19 20:58:51 |
 +-++---+-+---+--+--+-+--+---+---+-+

 When the job started Bacula took the tape L5BA0005 and never required
 another one. As you can see Bacula apparently wrote 2,058,019,117,056
 bytes (approx. 2 TB) but my tape is just 1.5 TB capacity. Does anybody
 know why? My job isn't using compression so I really don't understand
 this.


 The job may not be using compression but the tape drive itself may have 
 compression enabled, which could account for being able to write 2 TB to the 
 LTO-5 tape.

 (The 1.5 TB capacity is the native capacity of an LTO-5 tape without hardware 
 compression enabled.)

 Cheers,

 Paul.



Hi, excuse me if I'm a newbie on this but, how and where can I verify
if hardware compression is enabled? It would be on the web
administration of my tape library?

Thanks

 Hi,

 I'm using the TS3100 with a CentOS 5.5 and Bacula 5.0.3 and it's working 
 great.
 I don't think there are any mainstream Linux dist who won't work with this 
 auto changer unless they're too old.
 It works great with the mtx command also.

 /Patric

Thanks a lot for your comments, this gives me trust on buying that
autochanger soon.

I hope someone who had experiences with this hardware using bacula 
linux can share some words to this thread.

Thanks again, bye.

[Bacula-users] Experiences with Autochanger IBM TS3100

[Jason Voorhees]

Hi:

We're planning to buy a autochanger IBM T3100 but I would like you to
give me some suggestion about this model? Do you know if it's fully
supported with modern Linux distributions? Is it necessary some recent
kernel version? Is it difficult to configure? Would you recommend a
better linux distribution that support this device by default?

I hope someone can share with me some opinions before buy it. Thanks
