+## Backup
+
+Our backup strategy executes daily full backups and differential backups on much higher frequency.
+In a disaster recovery scenario, our goal is to guarantee a recovery point objective (RPO) of 1h, and a higher but similar recovery time objective (RTO).
+Under normal operations, RPO and RTO goals are below 1 minute.
+
+If you you have different requirements we provide you with a flexible approach to backup, restore, and transfer data (f.e. to a self-hosted setup) through our APIs.
+Please consult the [migration guides](../guides/migrate/introduction.md) for more information.
