Shared Cluster Backups

Atlas takes daily snapshots of M2 and M5 Shared clusters. Atlas takes these snapshots automatically starting 24 hours after you create your cluster.

Atlas always takes M2 and M5 snapshots from a secondary node to minimize performance impact.

Atlas retains the last 8 daily snapshots, which you can download or restore to an Atlas cluster.

Required Access

To manage backups for a cluster, you must have Project Owner access to the project. Users with Organization Owner access must add themselves as a Project Owner to the project before they can manage backups.

Limitations

  • Custom policies are not supported for M2 and M5 cluster snapshots. Atlas always takes a single daily snapshot at the same time, starting 24 hours after the cluster was created.

    If you require finer-grained backups, consider upgrading to an M10 or larger cluster tier.

  • On-demand snapshots are not supported for M2 and M5 clusters.

  • You can't restore M2 and M5 snapshots to a sharded cluster. You can only restore M2 and M5 snapshots to replica sets.

  • You can't restore Serverless instance snapshots to M2 and M5 clusters.

  • Starting with MongoDB 5.0, you can restore snapshots of clusters that run only the two most recent major versions of MongoDB to M2 and M5 clusters.

    For example:

    • You can restore snapshots taken from clusters that run MongoDB 4.4 to an M2 or M5 cluster that runs MongoDB 5.0.

    • You can't restore snapshots taken from clusters that run MongoDB versions earlier than 4.4 to an M2 or M5 cluster that runs MongoDB 5.0.

View M2/M5 Backup Snapshots

The Atlas CLI does not support M2/M5 backup snapshots.

Atlas displays existing snapshots for a given cluster on the Snapshots page. To view snapshots that Atlas has already taken:

1

In Atlas, go to the Clusters page for your project.

  1. If it's not already displayed, select the organization that contains your desired project from the Organizations menu in the navigation bar.

  2. If it's not already displayed, select your desired project from the Projects menu in the navigation bar.

  3. If it's not already displayed, click Clusters in the sidebar.

    The Clusters page displays.

2

Go to the Backup page for your cluster.

  1. Click your cluster's name.

  2. Click the Backup tab.

    If the cluster has no Backup tab, then Atlas backups are disabled for that cluster and no snapshots are available. You can enable backups when you scale the cluster.

    The Backup page displays.

3

Click Snapshots.

Alternatively, to view a list of all M10+ clusters with cloud backup enabled:

1

In Atlas, go to the Backup details for your project.

  1. If it's not already displayed, select the organization that contains your project from the Organizations menu in the navigation bar.

  2. If it's not already displayed, select your project from the Projects menu in the navigation bar.

  3. In the sidebar, click Backup under the Security heading.

    The Backup details display.

View the list of clusters.

If you choose to retain backups from a cluster you terminate, they remain accessible here under their source cluster name until they expire or you delete them.

The Atlas Administration API provides endpoints for retrieving one or all snapshots from a given M2 or M5 cluster:

Additionally, Atlas displays existing M2 or M5 snapshots in the All Daily Snapshots table. From this table, you can restore or download your existing snapshots.
