 Back Up with Atlas
 ------------------
 
-MongoDB Atlas, the official MongoDB cloud service, provides 2 fully-managed
-methods for backups:
-
-1. :atlas:`Continuous Backups </backup/continuous-backups>`, which take
-   incremental backups of data in your cluster, ensuring your backups are
-   typically just a few seconds behind the operational system. Atlas continuous
-   backups allow you to restore from stored snapshots or from a selected point
-   in time within the last 24 hours.  You can also query a continuous backup
-   snapshot.
-
-#. :atlas:`Cloud Provider Snapshots </backup/cloud-provider-snapshots>`, which
-   provide localized backup storage using the native snapshot functionality of
-   the cluster's cloud service provider.
+MongoDB Atlas, the hosted MongoDB service option in the cloud, offers
+two fully-managed methods for backups:
+
+1. :atlas:`Cloud Backups </backup/cloud-backup/overview>`, which
+   utilize the native snapshot functionality of the
+   deployment's cloud service provider to offer robust backup options.
+   Cloud Backups provide:
+
+   - :atlas:`On-demand snapshots
+     </backup/cloud-backup/overview/#on-demand-snapshots>`, which allow
+     you to trigger an immediate snapshot of your deployment at a given
+     point in time.
+
+   - :atlas:`Continuous Cloud Backups
+     </backup/cloud-backup/overview/#continuous-cloud-backups>`, which
+     allow you to schedule recurring backups for your deployment.
+
+#. :atlas:`Legacy Backups </backup/legacy-backup/overview/>`
+   *(Deprecated)*, which take incremental backups of data in your
+   deployment.
