Hello again,

i?ve found the problem.
"./rsync -v --copy-devices --progress 
--write-batch=/mnt/sdc1/snapshotvergleich/diff1 
/mnt/sdc1/snapshotvergleich/xp8main3-mnt-backup-base.img 
/dev/vg0/xp8main3-mnt-backup-1"
creates a diff1-file which has nearly the size of 
/mnt/sdc1/snapshotvergleich/xp8main3-mnt-backup-base.img because rsync 
with --copy-devices-param does not work as expected when a device is the 
target.

So my filesystem was overfilled and "rsync error: error in file IO (code 
11) at io.c(1565) [sender=3.1.0dev]" occured.

My next question:

Is it possible to tell rsync to treat a device-target lika a file?
