It all depends on what you're trying to do with it. If it's just for personal use, just encrypt it with a password and send it to Google drive or wherever. If you're trying to up for others, use this and you'll probably find what you're looking for
I like RapidShare and Mega, but as someone else said here, if you are trying to archive or share with a small audience, encrypt it and give it a generic filename and upload to your favorite normie service.
