Just to clarify, technically Hive for Mac only needs to be backed up once to allow you to restore access to the funds later, because it only has one address (which makes things simpler at the cost of privacy). Although of course we recommend backing up more regularly for various reasons (e.g. because there's some metadata saved with transactions which you lose if you rebuild the wallet from the blockchain).
(That said, I agree an Electrum cold storage with offline transaction signing is a better way to secure a larger amount of coins, I even have one myself.)
