Just add a layer of compression periodically to reclaim the wasted space and it will all work out.

If you have a compression that works on encrypted data, you can avoid wasting your time on the "encryption".

Base64 isn't encryption. The overhead added follows an extremely predictable pattern. That said I've no idea what the performance of common compression algorithms might be in such a use case. The comment was entirely tongue in cheek.
