Backup files are only written when writing a file, so wherever you set that option is fine as long as you do it before writing the file.

Swap files are written as soon as you open a file. You'll need to either use the new :noswapfile command modifier, or turn off swap files globally in your .vimrc. Your .vimrc gets executed prior to loading any files so that will be early enough.

Undo files are like backup files, they only write when you save the file or explicitly tell Vim to write one.
