Given the etcd version of the cluster, you can download backup via HTTP endpoint
-`http://${CLUSTER_NAME}-backup-sidecar:19999/backup?etcdVersion=${ETCD_VERSION}` . For example:
+`http://${CLUSTER_NAME}-backup-sidecar:19999/v1/backup?etcdVersion=${ETCD_VERSION}` . For example:
```
-$ curl "http://etcd-cluster-backup-sidecar:19999/backup?etcdVersion=v3.1.0" -o v3.1.0_etcd.backup
+$ curl "http://etcd-cluster-backup-sidecar:19999/v1/backup?etcdVersion=v3.1.0" -o v3.1.0_etcd.backup
```
"etcdVersion" parameter is the version of the potential etcd cluster to restore and run.
On success, the backup's etcd version should be compatible with given version.
