Last I checked RDS uploads transaction logs for DB instances to Amazon S3 every five minutes. Litestream by default does it every second (you can go sub second with litestream if you want).

Yes but there is still a (small) window where confirmed writes can be lost

Right and that window is bigger for RDS by the looks of it.

Interesting - I had not looked deep into this before.

Is suppose the difference is RDS has high 9s, whereas in the Litestream case the frequency of crashes is tied to your application code and deployment process. In practice this will take more work to reach the same uptime?
