Backup and Restore Sharded Clusters
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 Sharded Clusters with Database Dumps.
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 Sharded Clusters 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.
