Re: [Bacula-users] multiple spool files per job
Hi, this feature would be really great. We have three Backup serves which all have single Jobs to backup (each job app. 13TB). The Time to despool is absolutely waste of time and could be used more efficient. This feature request is more than 4 Years old and still not implemented. Maybe I am wrong and I am sorry to say this, but as the data volume is growing all the time and this feature is still missing, I've got a notion that Bacula is not anymore "up to date" or state of the art.

I believe this is in the todo list, but it will happen faster if someone submits already-written code. -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

h, thanks for the hint :-) At the moment both jobs are using one pool (differential pool). I allready searched in the archive but haven't found the solution.

If the jobs go to different pools then bacula should automatically choose the empty drive. If two jobs that you want to run at the same time go to the same pool the problem is getting bacula to load more than 1 volume from a pool at the same time. There are ways to do this.

Re: [Bacula-users] The number of files mismatch!
Hi Julien, this tapes were empty when I added the EOT. To explain: I made a full backup to tape mba022, added the EOT and wrote an inc in a different pool (for example tape mba056). This was working.

[Bacula-users] schedule writing and spooling on different drives and spool directorys
Hi all, I have a Tapeloader with 2 drives and a backupserver with a huge spool directory. Now I thought it would be nice to schedule the different drives and the time when it spools to have allways a maximum on network load and keep the time which is needed for the backup as short as possible. For example: 1. Backup job1 starts spooling data from server1 to \serv\spool1 2. drive1 starts writing after job1 stops spooling. At the same time Backup job2 starts spooling data from server2 to \serv\spool2 3. When drive1 has finished writing, it starts with despooling. 4. When Job2 has finished spooling, it starts writing to tape2. At the same time job1 or another job starts spooling again At the moment the jobs can start parallel and they need to share the 1GB Network. After spooling, there is no more traffic on the network.. This seems to be inefficient to me. Would this be a good solution and is this possible in bacula? What do you think?

Hi all, I have a strange behavior when I run btape. The test abborts at different positions. Sometimes it runs completely. Sometimes it stops after the rewind or after the "Got EOF on tape". I have no idea where I can search what's wrong. The strange thing is, that I was able to write (bconsole / run a job) on two tapes. After writing I tried to restore the job, but the restore failed. So I started from beginning with testing my Autoloader. And guess what. It failed. If I write an EOF manually (mt -f /dev/nst0 weof), the the test will work one time. The second time it fails again. Is this normal? I start btape with the following syntax: btape -c /dev/bacula/bacula-sd.conf -v -d 6 /dev/nst0 Here ist the btape output: btape: btape.c:831 Wrote 1000 blocks of 64412 bytes. btape: btape.c:505 Wrote 1 EOF to "Drive-1" (/dev/nst0) btape: btape.c:847 Wrote 1000 blocks of 64412 bytes. btape: btape.c:505 Wrote 1 EOF to "Drive-1" (/dev/nst0) btape: btape.c:856 Rewind OK. 1000 blocks re-read correctly.

Hi all, I found the following text inside of the manual: snipet If you would like to know what options you have set before making any of the changes noted above, you can now view them on Linux systems, thanks to a tip provided by Willem Riede. Do the following: become super user mt -f /dev/nst0 stsetoptions 0 grep st0 /var/log/messages and you will get output that looks something like the following: kernel: st0: Mode 0 options: buffer writes: 1, async writes: 1, read ahead: 1 kernel: st0: can bsr: 0, two FMs: 0, fast mteom: 0, auto lock: 0, kernel: st0: defs for wr: 0, no block limits: 0, partitions: 0, s2 log: 0 kernel: st0: sysv: 0 nowait: 0 end Isn't it easyer to use: mt -f /dev/nst0 stshowopt What do you think?

[Bacula-users] Backup Speed
Hi all, I have set up a new Backups System and I don't know whether the performance is good or not. So I hope you can tell me a little bit more :-) I am using a LTO4 Autoloader with 2 drives. It is connected to a Debian Backup Server trough an PCI-X SCSI Card (U320). This Server has another internal PCI-X SCSI Card (U320) which is connected to an external Raid (EasyRaid, 3*SATA HD's, Raid5, 1,9 TB). I am using this Raid for Spooling. The System Harddisk is an internal SAS RAID0 500GB. The Backup Server is connected to the Fileserver trough Gigabit LAN. Is this settup OK? Would you change something? Is the performane OK? If not, what do you think is the problem? Is it possible to write to 2 drives at the same time, to increase write performance? I know.This are a lot of questions, but I have no experience in Backup Systems :-) Thanks for your help, Stefan Logfiles: 08-Oct 15:40 BACKUP3-dir JobId 10: Start Backup JobId 10, Job=STORAGE4.2008-10-08_15.40.04 08-Oct 15:40 BACKUP3-dir JobId 10: Using Device "Drive-1" 08-Oct 15:40 BACKUP3-sd JobId 10: Spooling data ...
