There are three types of maintenance for ARO: upgrades, backup and restoration of etcd data, and cloud provider-initiated maintenance.

Upgrades include software upgrades and CVEs. CVE remediation occurs on startup by running yum update and provides for immediate mitigation. In parallel a new image build will be created for future cluster creates.

Backup and management of etcd data is an automated process that may require cluster downtime depending on the action. If the etcd database is being restored from a backup there will be downtime. We back up etcd hourly and retain the last 6 hours of backups.

Cloud provider-initiated maintenance includes network, storage, and regional outages. The maintenance is dependent on the cloud provider and relies on provider-supplied updates.

A short question to your answer, I can't find the section in your source, where the etcd backup is documented in the Azure Docs for ARO.
Is this an official statement that Azure will backup etcd automatically and I have to do nothing manually?
