I was sure I had put it in ;-)

I have limited the number of allowed volumes, volume size, volume
jobs. Volume retention is set to an useful value (14d). Automatic
pruning is on.

  AutoPrune = yes
  Volume Retention = 20 days
  Maximum Volumes = 14
  Maximum Volume Jobs = 6
  Maximum Volume Bytes = 4.3g

That is an argument. I have changed volume labelling to use simple
counts. Might be less confusing.

  Label Format = "${Client}_Inc_${Count}"

This is the case: not a single volume is created automatically. I
have to create the volume manually. But I do not see any error I've
made with my configuration.

Since there are no volumes at first start with this configuration,
the limit isn't reached jet. The volume shall be created.

I have tried this too, but it did not change anything. Volumes are
just not created. I can create them manually, but this is not really
an option :-(

Maybe it could help if one has a running configuration with
autocreating volumes as needed? Maybe it is more easy to compare my
configuration against a working one?!
