the --whole-file option didn't help. The second full backup since
changing to rsync has finished now, and it took 600 min. less than the
last couple of full backups before. On the other hand the incremental
backups now need 3-4h in contrast to 60-80 min. before.

I'll stay with rsync for now, maybe with a longer interval between the
full backups. rsync should catch moved/deletet files.
