The following list describes the rules for entering the dump command:
option can be a list. You must list all options together; do not separate the options
by commas or spaces.
argument can be a list of arguments, each of which is associated with an option.
The arguments are separated by spaces.
If an option takes a list of arguments, the arguments in the list are separated by
commas.
List the arguments in the same order as you list the options.
The dump level must be the first option. You can type other options in any order.
path is the complete path name of the file or directory to be backed up by the
dump command.
Always precede the volume name by /vol/ even though the volume is a root
volume. This is because between different levels of backups, you might have
changed the root volume.
NOTE: Some options do not have any arguments.
