But we are talking about database here. Backuping uploads to S3 every few minutes is just stupid.
But still I would like to hear why this is so big question.
There is no in-build solution by Autommatic at all. But there is a plenty options why there is no need to build such functionality. The whole ecosystem is different and Discourse as an environment is lacking such variety totally. Everything here is strongly build on B2B, I know it, and there is no need nor want to develop similar customer level solution than WordPress and its plugins are.
All I want to know what is the real reason why this is so hard question.
