Evaluate this below to get into Info file:

(info "(emacs) Auto Save Files")

   The variable ‘auto-save-file-name-transforms’ allows a degree of
control over the auto-save file name.  It lets you specify a series of
regular expressions and replacements to transform the auto save file
name.  The default value puts the auto-save files for remote files
(*note Remote Files::) into the temporary file directory on the local
machine.

On my side the variable ‘auto-save-file-name-transforms’ looks as
this:

[INS] [DEL] List:
            Regexp: \`/[^/]*:\([^/]*/\)*\([^/]*\)\'
            Replacement: /home/data1/protected/tmp/\2
            Uniquify: [Toggle]  on (non-nil)


or as this:

auto-save-file-name-transforms ⇒ (("\\`/[^/]*:\\([^/]*/\\)*\\([^/]*\\)\\'" 
"/home/data1/protected/tmp/\\2" t))
