+# Restore from backup example
+
+This example provides an end-to-end executable flow of how a Elasticsearch DB instance can be created from a backup instance. This example uses the IBM Cloud terraform provider to:
+
+- Create a new resource group if one is not passed in.
+- Create a restored ICD Elasticsearch database instance pointing to the lastest backup of the existing Elasticsearch database instance crn passed.
