+Note that the data is automatically encrypted on the server. The key will be generated and added to your config file. Every backend will have a separate key. **You should keep a copy of the keys or config file somewhere in case your server dies**. Otherwise DATA IS LOST!
+
+Also, currently comments in the config file will be deleted, due how the yaml parsing library works. I will fix this soon :)

+## ❓ QA

+### My config file was moved?
+
+This happens when autorestic needs to write to the config file. This happend e.g. when we are generating a key for you.
+Unforunately during this process formatting and comments are lost. That is why autorestic will place a copy of your old config next to the one we are writing to.
