Asynchronously overwrites the file, replacing the contents, possibly creating a backup copy of the file first.

For more details, see Gio.File.prototype.replace which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call Gio.File.prototype.replace_finish to get the result of the operation.
