vim: how to stop vim from generating ANY additional files?

the question is in the subject, I've been with VIM daily for quite a
while and I normally is OK with it.
but I just reallized it's not good if I generate a lot of additional
files when I change some config file in my linux FS.
typically they are sth like:

asciidoctips.txt~
.asciidoctips.txt.un~

.pers-notes.txt.swh
.pers-notes.txt.swi
.pers-notes.txt.swj
.pers-notes.txt.swk
.pers-notes.txt.swl
.pers-notes.txt.swm
.pers-notes.txt.swn
.pers-notes.txt.swo
.tech-tips2.txt.swp

just want to confirm, to make sure there is not a single additonal file
generated by vim under all circumstances, are following settings sufficient?

set nobackup
set noudf

thanks!
