man ufsdump

The following options are supported:

      0-9  The "dump level." All files specified by files_to_dump
           that  have  been  modified since the last ufsdump at a
           lower dump level are copied to the dump_file  destina-
           tion  (normally a magnetic tape device). For instance,
           if a  "level  2" dump was done on Monday, followed  by
           a  "level  4" dump on Tuesday, a subsequent "level  3"
           dump on Wednesday would contain all files modified  or
           added  since  the "level  2" (Monday) backup. A "level
           0"  dump  copies  the  entire  file  system   to   the
           dump_file.
