Indeed. ange-ftp supports (poorly) file-attributes, but file-modes:
(file-exists-p "/ftp:localhost:.emacs")
t
(file-modes "/ftp:localhost:.emacs")
nil
(file-attributes "/ftp:localhost:.emacs")
(nil -1 -1 -1 (0 0) (0 0) (0 0) -1 "-?????????" nil 2 -1)

The invocation of ange-ftp seems to be correct AFAICS.
I don't see the point why Tramp shall support find-backup-file-name
this case. This function is forwarded to ange-ftp always (because the
FTP method is active). ange-ftp hasn't implemented this method, but
forwards it to the default handler. And this one doesn't know what to
do:
(find-backup-file-name "/ftp:localhost:.emacs")
nil
According to the documentation this is a valid answer ("If the value
is nil, don't make a backup.") Usually there doesn't seem to be a
problem if ange-ftp is used without Tramp. Hmm.
Best regards, Michael.
