Shared Cluster Backups¶
Atlas takes daily snapshots of M2 and M5 shared clusters.
Atlas takes these snapshots automatically starting 24
hours after the time you create your cluster.
You must have the Project Owner role for an Atlas
project to manage backup for the clusters in that project.
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.
Snapshot Storage Location¶
Atlas stores M2 and M5 cluster snapshots as per the
following table:
Cluster Location | Snapshot Storage Location |
|---|---|
Australia | Australia |
Germany | Germany |
Hong Kong | Australia |
India, Singapore, Taiwan | Asia |
USA | USA |
All other cluster locations | Ireland |
Access M2/M5 Snapshots¶
Atlas displays existing snapshots on the Snapshots page. To view your snapshots:
- Click Databases in the top-left corner of Atlas.
- From the Database Deployments view, click the cluster name.
- Click the Backup tab.
Atlas displays existing snapshots in the All Daily Snapshots table. From this table, you can restore or download your existing snapshots.
Limitations¶
Custom policies are not supported for
M2andM5cluster 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
M10or larger cluster tier.- On-demand snapshots are not supported for
M2andM5clusters. - You can't restore
M2andM5snapshots to a sharded cluster. You can only restoreM2andM5snapshots to replica sets. - You can't restore serverless instance snapshots to
M2andM5clusters.
