The following tutorials describe backup and restoration for sharded clusters:
Tip
To use mongodump and mongorestore as a backup
strategy for sharded clusters, see Back Up a Self-Managed Sharded Cluster with a Database Dump.
Sharded clusters can also use one of the following coordinated backup and restore processes, which 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 Self-Managed Sharded Cluster with a Database Dump
- Create backups using
mongodumpto back up each component in the cluster individually. - Schedule Backup Window for a Self-Managed Sharded Cluster
- Limit the operation of the cluster balancer to provide a window for regular backup operations.
- Restore a Self-Managed Sharded Cluster from Snapshots
- An outline of the procedure and consideration for restoring an entire sharded cluster from backup.
- Restore a Self-Managed Sharded Cluster from Database Dumps
- Restore a sharded cluster from a backup created with
mongodump.
