[Bacula-users] Performance problems in migration from disk to tape
Hi, My configuration is roughly like this: I back up about 10 hosts to disk volume using bacula and migrate the backups to tape once a week. Backups work ok, the resulting volume file on disk is currently about 25 Gb. I have also some backups going directly to tape, performance there is also ok. But the weekly migration job, which moves backups from disk volume to tape is really slow. For example: Elapsed time: 7 mins 14 secs SD Files Written: 2 SD Bytes Written: 3,913,732 (3.913 MB) A relatively small backup job, only a couple of megabytes took more than 7 minutes. When I looked at the machine, it was doing heavy disk io, tape is mostly idle. This sounds a little bit similar as issue discussed here earlier: http://www.mail-archive.com/bacula-users@lists.sourceforge.net/msg31142.html I wonder if there was any solution, configuring things differently maybe ?

[Bacula-users] Bacula dir work very slow with huge number of restore file
Hello All Bacula Users, I found that Bacula is very slow when restore action is used for large number of files to restore. This affect only director but is/can be a problem. I've to restore a backup with over 5'000'000 files inside. After mark and done actions I've been waiting over 10 hours to follow next steps. But I couldn't wait more. At least I've split this action for pieces to complete this. I've take a conclusion that file set about 1'000'00 takes about 3h to completion. Did you experienced this issue? How to solve/work around of this? Is it a bug (Denial of service for 10 hours waiting to dir will recalculate needed items)?

Hello,
I've been trying out bacula-2.5.16-beta, and I've tried to use bpipe to
backup
my mysql database. I think that I have done everything right, having
followed
the instructions on this page...
http://www.bacula.org/manuals/en/concepts/concepts/New_Features.html
...but it doesn't want to work. Perhaps somebody can give me a hint?
(Incidentally, that web page mentions a 'bpipe-dir.so', as well as a
'bpipe-fd.so', but I think that there is no 'bpipe-dir.so' - at least, I
can't find one)
I set this in my fileset (in the director config), and test that the
mysqldump
command works when I run it from the command line:
FileSet {
Name = $NAME
Include {
Options {
signature = MD5
compression = GZIP9
}
File=/chroot/write/html
(and some others...)
Plugin = bpipe:/var/spool/backup-out/MYSQLPIPE:mysqldump -f
--all-databases:mysql
}
I set this in the file daemon config:
FileDaemon {
Name = tserv.example.com-fd
FDport = 9102
WorkingDirectory = /var/lib/bacula
Pid Directory = /var/run
Maximum Concurrent Jobs = 20
PKI Signatures = Yes
PKI Encryption = Yes
PKI Keypair = /etc/bacula/bacula-client-keys-base
Plugin Directory = /etc/bacula/plugins
}
I make sure that 'bpipe-fd.so' is in /etc/bacula/plugins.
The permissions all look fine (the file daemon runs as root, so it should be
ok).
-rwxr-xr-x 1 root root 23485 Dec 4 15:05 bpipe-fd.so
I restart all the daemons and run my job from bconsole, which backs up all
my
files OK, but at the end, I get this message come out on bconsole...
*bpipe-fd: plugin=bpipe fname=/MYSQL/regress.sql reader=mysqldump -f --opt
--databases bacula writer=mysql
...my log says this, and the Job finishes with status 'Error':
Dec 4 15:25:09 bacula-dir: tserv.example.com-fd JobId 12: Fatal error:
Pipe read error: ERR=Success
So. Any ideas?
Has anybody else managed to use bpipe successfully?
I've now tried bpipe with bacula-2.5.28-b1, and I don't even get the error
anymore, though the backup reports 'Backup OK'. I've tried changing my
Plugin = bpipe:... line so that it has a nonsense command, and there is
still no error.
The run with the nonsense command backed up as much stuff as the proper
command When I revert to my old RunScripts, I can see that a lot more stuff
gets backed up than with my bpipe attempts. So it seems as if bpipe isn't
working at all.
I would like to know whether anybody else has managed to use bpipe
successfully.
(Later...) I see that one of the SVN regress tests makes a mention of bpipe,
so I will give that a go.

Re: [Bacula-users] products based on bacula
I've got to defend management here. IME, they DO ask for evaluations, reports, executive summaries, the works. But they only ask it for the short list of products after an initial culling, often only between the two or three finalists. How many commercial enterprise backup systems are there on the market? More than that, I'm sure. That's where marketing matters. Marketing isn't about selling. It's about getting on the short list. THEN you can let the product sell itself on the merits. Bacula has strengths and weaknesses in that area. Strength: viral marketing. Those in the know - us - appreciate the quality, and can work to get it onto the short list. Strength: reasonable visibility within the Open Source community. I discovered it because it had administration modules in webmin. Weakness: the name and tag line. It doesn't matter when selling on the merits, but it's a huge issue with getting on the short list. Weakness: little known outside Open Source. That's a double-whammy since many managers still tend to be skeptical of Open Source to begin with. Weakness: no slick brochures, white papers, etc. When a manager asks his employee give me a short list of backup solutions, the employee will start with google and download whitepapers and executive summaries. And, no, the What is Bacula page does not count. And let's also not forget: (most) managers aren't in the business of promoting Open Source. They are in the business of solving their business problems. Sometimes, Open Source is the answer, sometimes it isn't. As a consultant, I advise many customers to buy Microsoft servers. I personally prefer Linux servers, but for many situations, Windows really is the better solution. I'm running a mix of both in my own office. And I warn my customers of using OpenOffice. But I point them to the Gimp for image manipulation. I host their Web sites on LAMP. etc. etc. Ultimately, solving the problem matters - and licensing cost is only one factor in the equation. Very often a minor one.

Re: [Bacula-users] Bacula dir work very slow with huge number of restore file
Just a thought: for the future, maybe splitting up the file set and using several smaller backup jobs might help with this type of situation? It's probably something that you can't always do, plus it may wreak havoc with such things as snapshots.

If you want the new drive to be able to share media with the old drive, you should use the same media type. If not, you should have them be different. It would be best if you could make a supported media type list, to allow for backward compatible drives, but that's not possible at present. This is something I raised at least 2-3 years ago. There's been no apparent interest in solving the issue and likely won't be until one of the developers encounters the problem. Supported media lists would have to cover r/w and ro support: LTO drives are r/w compatible with the previous generation, but read only with the one before that. ie: LTO4 can R/W LTO3 tapes, but only read LTO2 and can't read LTO1 at all. (As far as I can tell these are _minimum_ specs for LTO. It's perfectly possible to exceed them and produce a LTO4 drive which can write LTO2 and read LTO1, but as far as I know no manufacturer has done that yet. Sure about that?, the marketing material I've seen shows only read-only capabillity one-generation back and write capabillity one generation, if the tape was un-used before (never written before). -- Jesper -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
[Bacula-users] NAS unit for bacula backups
Hi, Has anyone tried to use a network storage unit for doing bacula backups? I have a new Linksys NAS200. My idea is to mount two large sata drives and direct bacula to use them somehow. When those two become full store them and then mount 3 and 4 Etc. I wonder if that can work? And are there risks associated with storing SATA drives in a box say?

Re: [Bacula-users] products based on bacula
Nice post Kevin. On Fri, Jan 23, 2009 at 5:20 AM, Kevin Keane subscript...@kkeane.com wrote: I've got to defend management here. IME, they DO ask for evaluations, reports, executive summaries, the works. But they only ask it for the short list of products after an initial culling, often only between the two or three finalists. How many commercial enterprise backup systems are there on the market? More than that, I'm sure. That's where marketing matters. Marketing isn't about selling. It's about getting on the short list. THEN you can let the product sell itself on the merits. Bacula has strengths and weaknesses in that area. Strength: viral marketing. Those in the know - us - appreciate the quality, and can work to get it onto the short list. Strength: reasonable visibility within the Open Source community. I discovered it because it had administration modules in webmin. Weakness: the name and tag line. It doesn't matter when selling on the merits, but it's a huge issue with getting on the short list. Weakness: little known outside Open Source. That's a double-whammy since many managers still tend to be skeptical of Open Source to begin with. Weakness: no slick brochures, white papers, etc. When a manager asks his employee give me a short list of backup solutions, the employee will start with google and download whitepapers and executive summaries. And, no, the What is Bacula page does not count. And let's also not forget: (most) managers aren't in the business of promoting Open Source. They are in the business of solving their business problems. Sometimes, Open Source is the answer, sometimes it isn't. As a consultant, I advise many customers to buy Microsoft servers. I personally prefer Linux servers, but for many situations, Windows really is the better solution. I'm running a mix of both in my own office. And I warn my customers of using OpenOffice. But I point them to the Gimp for image manipulation. I host their Web sites on LAMP. etc. etc. Ultimately, solving the problem matters - and licensing cost is only one factor in the equation. Very often a minor one.

Re: [Bacula-users] Mixed Drives
Anyway, personally, I'd like to see Alans suggestions implemented, but neither I nor any of my customers has a setup where that would be needed... the original poster might think about how they could support development here :-) Believe me, I'd love to support the development of Bacula especially in this area. Unfortunately, we have a serious shortage of man power in my area to dedicate to coding. I would be willing to help with testing to a point as we only have the one library and it is used for production, it would have to be sandboxed to certain tapes for testing purposes. An overall idea that I've had is when a job is run, it finds the pool to put/get the data and knows the SD, the DIR queries the SD to find the supported media for the devices then selects a drive that matches the media from the volume. This would remove the Media directive from the SD directive in the Director config. To extend this to support backwards compatibility, the media directive could be split into media-write, media-read directives which could either support multiple directives or a delimited list of media the drive supports. This list would be fed back to the director when the DIR queries the SD for devices to choose an appropriate device. When we have time and resources we will look into coding it, but don't hold your breath on that being anytime soon.

If you can mount the NAS unit onto the Bacula box's filesystem, then yes, you can do backups to disk.
