[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 ?

Hello, This is know problem in bacula versions up to 2.4.4 It is fixed in recent beta 2.5.28-b1 We are running the same Setup (just Copy instead of Migrate) 30 Clients CopyDiskToTape weekly full backups (~600GB) takes 3 hours CopyDiskToTape daily incr backups (~30GB) takes 10 minutes Regards Ulrich Regards, Ari Suutari -- 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 -- Ulrich Leodolter ulrich.leodol...@obvsg.at OBVSG -- 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

What version of Bacula are you running? Which OS? What kind of hardware do you have? :) -- Pasi -- 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

Hi, What version of Bacula are you running? Which OS? What kind of hardware do you have? :) Sorry, I forgot those: Bacula 2.4.4, FreeBSD 7.1, disks are SATA disks and tape is HP DAT160.

Re: [Bacula-users] Performance problems in migration from disk to tape
Hi, This is know problem in bacula versions up to 2.4.4 It is fixed in recent beta 2.5.28-b1 This sounds great ! Are there any possibilities that the fix might be seen in future 2.4 versions, or should I just upgrade to beta versions ? Using beta versions is tempting, because I would like to use Copy jobs also.
