No. Both variables are independent from each other. I just have seen
that you did configure `tramp-auto-save-directory' for a local
directory; and I did recommend to do the same for
`tramp-bkup-backup-directory-info'.

Then you need to reduce the password requests from Tramp. Which access
method do you use? An external method like "scp"? Change it to "ssh".

Or set `password-cache-expiry' to nil.
