Not so simple. It would require a local setting of
`backup-directory-alist' in case of Tramp files, maybe in the
`find-file-hook'.

Hmm. I've tried this one:

(add-to-list 'backup-directory-alist
             (cons "." "~/.backup"))

That gave me exactly what you wanted. I've tested it with the CVS
version of Tramp; I vaguely remember there has been some problems in
the past fixed meanwhile, but I cannot identify the corresponding
Changelog entry.

Emacs disables backups checking `make-backup-files'. Your desired
behaviour would require to set this variable locally, again, for Tramp
files.
