To be fair, using redis or elasticsearch as a main datastore is doable. Although I'm not sure they're much better choices in terms of understanding how they work.

You could summon Antirez I guess

Doesn't redis by default have recovery via the filesystem enabled?

It does - BUT depending on how often you have it syncing changes to disk you can lose data.
