hi,

i've an incremental-job which looks like doing a differential instead.
i did a full manually to a different pool (retention one year), becouse 
i need only incremental each day. you could see the config for that
incremental daly job here:

[...]

JobDefs {
  Name = "SubsJob"
  Type = Backup
  Level = Incremental
  Schedule = "Subs"
  Storage = storage01
  Messages = Standard
  Pool = SUBSINC
  Priority = 10
  SpoolData = yes
  Maximum Concurrent Jobs = 10
}

Pool {
  Name = SUBSINC
  Pool Type = Backup
  Recycle = yes            
  RecyclePool = SUBSINC
  RecycleOldestVolume = yes            
  AutoPrune = yes           
  Volume Retention = 60 days
  Maximum Volume Bytes = 128849018880  
  LabelFormat = SUBSINC  
  Maximum Volumes = 5   
}

Schedule {
  Name = "Subs"
  Run = Incremental mon-fri at 19:00
}


Client {
        Name = client01-fd
        Address = client01.intern.domain.de
        FDPort = 9102
        Catalog = MyCatalog
        Password = "nnn"
        File Retention = 60 days
        Job Retention = 6 month
        AutoPrune = yes
}

Job {
        Name = client01
        JobDefs = "SubsJob"
        Write Bootstrap = "/var/lib/bacula/client01.bsr"
        Client = client01-fd
        Priority = 10
        SpoolData = yes
        Maximum Concurrent Jobs = 10
        FileSet = "client01"
}

FileSet {
        Name = "client01"
        Include {
                Options {
                  signature = MD5
                  compression = GZIP
                }
        File = /root/bin
                File = /home
                File = /etc
                File = /var/spool/cron/crontabs
                File = /storage/ADMIN
        }
        Exclude {
                File = /.journal
                File = /.fsck
        }
}

[...]

but since the manual full each incremental has the same files of 
the incremental before, and some new files...

start:          2008-08-14 18:09:36     
duration:               14:13:01

start:          2008-08-20 19:00:01     
duration:               10:31:47

level:          Incremental

so it looks like a differential, becouse it's realy hughe and
the number of files in each incremental are growing just for
some files...

there always about 13 hours between the jobs, so that they dont
overhaul each other...

i've the same problem on two different jobs/clients - with similar 
config and pool..

 
client-log of the last job -  the backup level seems to be ok...

any ideas, what's my fault?
