Yes, using separate pools would prevent media sharing. You could also try setting Maximum Concurrent Jobs = 1 in the Device directive in the Storage Daemon. See:
http://www.bacula.org/7.0.x-manuals/en/main/Storage_Daemon_Configuratio.html#SECTION001730000000000000000 http://www.bacula.org/7.0.x-manuals/en/main/New_Features_in_5_2_13.html#SECTION00451000000000000000 Maximum Volume Jobs is documented as broken when using multiple simultaneous jobs (http://www.bacula.org/7.0.x-manuals/en/main/Configuring_Director.html#SECTION0015150000000000000000). __Martin >>>>> On Fri, 25 Jul 2014 10:14:54 +0200, tballin said: > > Hi, > thanks for the reply.
