  • Limitations of Cloud Backup


Feature Unavailable in Free-Tier Clusters

This feature is not available for M0 free clusters. To learn more about which features are unavailable, see Atlas M0 (Free Cluster), M2, and M5 Limitations.

Atlas Cloud Backups provide localized backup storage using the native snapshot functionality of the cluster's cloud service provider.


You must have the Project Owner role for an Atlas project to manage backup for the clusters in that project.

Atlas supports cloud backup for clusters served on:

You can enable cloud backup during the cluster creation or during the modification of an existing cluster. From the cluster configuration modal, toggle Turn on Cloud Backup to Yes.

If you have strict data protection requirements, you can enable a Backup Compliance Policy to protect your backup data.

If you need to retain any legacy backup snapshots for archival purposes, download them before you switch to Cloud Backup from legacy backups. To learn how to download a snapshot, see Restore a Cluster from a Legacy Backup Snapshot.

When you change from Legacy Backups to Cloud Backups, Atlas retains your Legacy Backup snapshots in accordance with your legacy backup retention policy.

Cloud Backups can support sharded clusters running MongoDB version 4.0 or later.

You cannot restore an existing snapshot to a cluster after you add or remove a shard from it. You may restore an existing snapshot to another cluster with a matching topology.

With databases running FCV 4.0 or earlier, Cloud Backup automatically disables the balancer if it is running in order to take a snapshot. When the snapshot completes, Cloud Backup returns the balancer to its previous state.
