- The etcd node mostly stores metadata like storage manifest and table catalog.
- The meta service backed by etcd is used for coordination.
- Persistent states are stored in S3 and the meta store (etcd).
- Backing up data in S3 can be done using tools like rclone or the provided meta backup tool from RisingWave.
- Currently, only reading backup information via SQL is exposed, but there are plans to allow backup commands via SQL in the future.
