string 'copy' as verb versus noun

$string['copy'] = 'copy';

This is used in several places as a verb and that is how the language packs translate it (correctly).

However, the backup module uses it as a noun in the restore to new file function to produce the name of file. This works fine in English but not in other languages. This is, however, really a cosmetic problem since restored courses are usually immediately renamed. But, it looks a bit strange to see

xxxx_kopiuj_1 (in Polish)

xxxx_kopiere_1 (in German)

which in English would be equivalent to

xxxx_copying_1 or xxxx_to_copy_1 or xxxx_do_copy_1
