At least, your data won't be visible to Mega or the Feds. And if they get raided, the Feds won't have shit against Mega or you. About the backup part, they have servers in different countries, so it's safer. Personally, I wouldn't rely on any service alone, I always have an extra copy somewhere else. I do the same with my emails for example. If tomorrow my email provider shuts me down, I will lose at most ~12 hours of emails. All my other emails are in my PC and in Dropbox (encrypted, obviously). Next, I sign up to a different email provider, change my domain DNS, and keep receiving emails normally like if nothing happened.
