Some hours ago I did a level 0 dump with the following command: dump -a -0 -f /mnt/da0/backup-compaq.0.dump / This results in a quite big dump file. After changing a couple of files, I tried to do another dump. This time as level 1. My expectation was that the resulting dump would only contain the files which changed since the level 0 dump. dump -a -1 -f /mnt/da0/backup-compaq.1.dump / To my surprise this seems to generate another full dump instead of incremental. What did I miss or what mistake do I make? The filesystem is mounted with the following options: ufs, local, journaled soft-updates Regards, Matthias
