No, this has been on the feature requests list for a while now. Spooling nearly doubles my time for large backups. http://thread.gmane.org/gmane.comp.sysutils.backup.bacula.devel/15351 Item 10: Concurrent spooling and despooling within a single job. http://www.bacula.org/git/cgit.cgi/bacula/plain/bacula/projects?h=Branch-5.1 Ralf ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2dcopy2 _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
