That’s what I was trying to explain in the other thread. The actual servers and services are on Azure, but the InfluxDB Cloud infrastructure infrastructure belongs to and is managed by InfluxData. InfluxDB Cloud does not launch Kubernetes clusters on your personal Azure services.
Currently, InfluxDB Cloud doesn’t provide a way to export and store data as a backup, but as a service, it does ensure your data is secure (see InfluxDB Cloud data durability). It is possible to query data out in time-based batches and store each batch elsewhere, but this is a very manual process. There may be some other backup options that I’m not aware of, but you would have to talk to the InfluxData sales team.
