I have tried to use this feature without success. I am using Bacula 7.0.5 and 
the following is the directives I use. Hopefully someone can pinpoint what I am 
doing wrong:

JobDefs {
   Name = "DefaultJob"
   Type = Backup
   Level = Incremental
   Accurate = yes
   Client = epohost-fd
   FileSet = "Full Set"
   Storage = FileStorage
   Messages = Standard
   Pool = Files
   Priority = 10
}

#
# Define the main linux system back-up job
#
Job {
   Name = "BackupEpohost"
   JobDefs = "DefaultJob"
   Schedule = "epohost-WeeklyCycle"
   Write Bootstrap = "/var/spool/bacula/epohost.bsr"
# Set up truncation of purged volumes
   RunScript {
     RunsWhen=After
     RunsOnClient=No
     Console = "purge volume action=truncate storage=FileStorage pool=Files"
   }
}

#
# Pool definition for Virtual Machines Backups
#
Pool {
   Name = Files
   Action on Purge = Truncate
   Maximum Volume Jobs = 0
   Maximum Volume Files = 0
   Pool Type = Backup
   LabelFormat = "Files"
   Recycle = yes                       # Bacula can automatically recycle 
Volumes
   AutoPrune = yes                     # Prune expired volumes
   Maximum Volumes = 50
   Maximum Volume Bytes = 20g
   Recycle Oldest Volume = yes
   Volume Retention = 3 months         # Three months
}
