However, I run into an issue that made me question if I understood dump right. On Feb 1 I had a level 0 backup of root file system. On Feb 2 and Feb 3 I had level 2 backups of the same file system. In all cases I used newfs prior to restore. I then tried to restore (Case A): Feb 1 Level 0, ok Feb 3 Level 2, reported errors (don't error message; got prompt y/n, then message with option to abort and report core dump) I tried again (Case B): Feb 1 Level 0, ok Feb 2 Level 2, ok Feb 3 Level 2, error: Incremental dump too high So, I got my system restored, but I am confused why Feb 3 backup did not restore in Case A. It has nothing to do with corrupted files, because I had the same issue on other file system and it worked the same way.
