Backup and Restore Cluster Data

Backups are copies of your data that encapsulate the state of your cluster at a given time. Backups provide a safety measure in the event of data loss.

Considerations

Be aware that:

  • Atlas backups are not available for M0 (Free Tier) clusters. You may use mongodump to back up your M0 cluster data and mongorestore to restore that data. To learn how to manually back up your data, see Command Line Tools.

  • You must restore the backup to a cluster running either the same major release version, or the next higher one. Atlas does not support restoring to older versions.

    You can still use backups made before an upgrade. For example, you can restore a 3.6 cluster to 4.0 with the following procedure:

    1. Restore the old 3.6 backup to another 3.6 cluster.
    2. Upgrade the restored cluster to 4.0.

Cloud Provider Snapshots

Available in M10+ Clusters.

Atlas uses the native snapshot capabilities of your cloud provider to support full-copy snapshots and localized snapshot storage.

Atlas supports cloud provider snapshots on:

Continuous Backups

Available in M10+ Clusters.

Continuous Backup Deprecated

MongoDB deprecated the Continuous Backup feature. Clusters that use Continuous Backup can continue to use it. MongoDB recommends using Cloud Provider Snapshots. Effective 23 March 2020, all net new clusters can only use Cloud Provider Snapshots.

Atlas uses incremental snapshots to continuously back up your data. Continuous backup snapshots are typically just a few seconds behind the operational system.

Atlas ensures point-in-time backup of replica sets and consistent, cluster-wide snapshots of sharded clusters.

For each Atlas project with continuous snapshots enabled, Atlas stores the continuous backup snapshots in the backup data center location where continuous backups were first enabled for a cluster in the project.

Continuous snapshots support restoring from the full snapshot or from a point-in-time between snapshots. You can also query a continuous snapshot.

With Atlas continuous backup, the total number of collections across all databases in a Atlas cluster cannot equal or exceed 100,000.

To learn more about Continuous Backups, see Continuous Backups.

To learn how to restore cluster from a Continuous Backup, see Restore a Cluster from a Continuous Backup Snapshot.

M2 / M5 Snapshots

Backups are automatically enabled for M2 and M5 shared-tier clusters and cannot be disabled. Atlas takes daily snapshots of your M2 and M5 clusters which you can restore to clusters tiers M2 or greater.

To learn more about M2 / M5 daily snapshots, see M2/M5 Snapshots.
