Re: [Bacula-users] Continue to spool to disk when tape is full?
If I understand the documentation correctly, raising dir.conf Maximum Concurrent Jobs will interleave multiple backups to tape, which I want to avoid. Not if you use data spooling. Bacula is capable of only one spool file, it seems? Each job is spooled to a separate file, which is deleted as soon as the job is completely despooled. I suppose a more specific question would be can I have Bacula close a spool file if it cannot despool, and write to tape when it is available? AFAIK Bacula will not start a job unless it can mount a suitable volume, even if the job is configured to use data spooling. However, if you have multiple jobs and enable concurrency, you can start a batch of spooled jobs at the same time (ie when the tape is empty); completed jobs will then be despooled one at a time. In this scenario a blocked drive will only halt despooling: incomplete jobs will keep spooling until they are all finished or the configured spool size limit is reached. andrea -- Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
