Maybe just `file-backup-files' or even just `backup-files'.

I think generally for a list of file names we just
say "files", not "file-names".  E.g. `directory-files*',
`tags-table-files'.  (Or we say `file-list'.) 

(There are of course other functions with "files" in the
name, which _act_ on files, and don't involve a list of
file names.)
