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.
Note
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.
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.Starting with MongoDB 5.0, you can restore snapshots of clusters that run only the two most recent major versions of MongoDB to
M2andM5clusters.Example
You can restore snapshots taken from clusters that run MongoDB 4.4 to an
M2orM5cluster that runs MongoDB 5.0.You can't restore snapshots taken from clusters that run MongoDB version earlier than 4.4 to an
M2orM5cluster that runs MongoDB 5.0.
