+The {oadp-first} product safeguards customer applications on {product-title}. It offers comprehensive disaster recovery protection, covering {product-title} applications, application-related cluster resources, persistent volumes, and internal images. OADP is also capable of backing up both containerized applications and virtual machines (VMs). 
+
+However, OADP does not serve as a disaster recovery solution for xref:../../backup_and_restore/control_plane_backup_and_restore/backing-up-etcd.adoc#backup-etcd[etcd] or OpenShift Operators.

+= {oadp-full} APIs

+{oadp-first} provides APIs that enable multiple approaches to customizing backups and preventing the inclusion of unnecessary or inappropriate resources.
