Backup and Restore Sharded Clusters

The following tutorials describe backup and restoration for sharded clusters:

Tip

To maintain the atomicity guarantees of transactions across shards, use the coordinated backup and restore services provided by MongoDB Atlas or MongoDB Ops Manager. Manual backups and restores do not maintain the atomicity guarantees of transactions across shards.

Back Up a Sharded Cluster with File System Snapshots
Use file system snapshots back up each component in the sharded cluster individually. The procedure involves stopping the cluster balancer. If your system configuration allows file system backups, this might be more efficient than using MongoDB tools.
Back Up a Sharded Cluster with Database Dumps
Create backups using mongodump to back up each component in the cluster individually.
Schedule Backup Window for Sharded Clusters
Limit the operation of the cluster balancer to provide a window for regular backup operations.
Restore a Sharded Cluster
An outline of the procedure and consideration for restoring an entire sharded cluster from backup.
