+.It Fl F Ar script
+Run script at the end of each tape. The device name and the
+current volume number are passed on the command line.
+The script must return 0 if
+.Nm
+should continue without asking the user to change the tape, 1 if
+.Nm
+should continue but ask the user to change the tape.
+Any other exit code will cause
+.Nm
+to abort.
+For security reasons,
+.Nm
+reverts back to the real user ID and the real group ID before
+running the script.
+.It Fl h Ar level
+Honor the user
+.Dq nodump
+flag
+.Dp Dv UF_NODUMP
+only for dumps at or above the given
+.Ar level .
+The default honor level is 1,
+so that incremental backups omit such files
+but full backups retain them.
+.It Fl I Ar nr errors
+By default,
+.Nm
+will ignore the first 32 read errors on the file
+system before asking for operator intervention. You can change this
+using this flag to any value. This is useful when running
+.Nm
+on an active filesystem where read errors simply indicate an
+inconsistency between the mapping and dumping passes.
+.It Fl j Ar compression level
+Compress every block to be written on the tape using bzlib library. This
+option will work only when dumping to a file or pipe or, when dumping
+to a tape drive, if the tape drive is capable of writing variable
+length blocks. You will need at least the 0.4b24 version of restore in
+order to extract compressed tapes. Tapes written using compression will
+not be compatible with the BSD tape format. The (optional) parameter
+specifies the compression level bzlib will use. The default compression
+level is 2. If the optional parameter is specified, there should be no
+white space between the option letter and the parameter.
