Some facts about the DLE:
The DLE is a subdirectory of a mounted LV (LVM2) part of a PV configured as
RAID1:
fstab: /dev/Store01-Data/Bilder /storage/bilder ext3
suid,exec,nodev,user_xattr 0 0
Try running
stat --format="%D" /storage/bilder/
over the course of a couple days, and see if the Device number
changes between the level 0 run and the as-big-a-level-0 level 1 run.
(LVM assigns the device numbers dynamically, so it's quite possible for
the numbers to change over the course of a reboot, etc.)
If the numbers are changing, then this page should hopefully tell you
what you need to know:
http://wiki.zmanda.com/index.php/Tar_dumps_every_file_in_a_level-1_backup_after_a_hardware_change
(Or, if you want to investigate more quickly, you could try using the
tar-snapshot-edit script mentioned on that page to examine the snapshot
files from your various runs and see if the device number has indeed
changed. [On Ubuntu, you'll find those snapshot files under
/var/lib/amanda/gnutar-lists on the client machine.])
I created a cronjob to record the ID every day at midnight (the same
time, when the backup starts. I'll keep you updated about that in a few
days.
A quick investigation is a bit confusing as the output is not as expected:

I wonder that the old snap files for level 5 and 6 from a former
dumpcycle were not deleted, but maybe that this is a normal behaviour.
