If applications modify data while mongodump is creating a backup, mongodump will compete for resources with those applications. 

See Back Up and Restore with MongoDB Tools (page 249), Backup a Small Sharded Cluster with mongodump (page 255), and Backup a Sharded Cluster with Database Dumps (page 258) for more information. 

## MongoDB Cloud Manager Backup 

The MongoDB Cloud Manager 2 supports the backing up and restoring of MongoDB deployments. 

MongoDB Cloud Manager continually backs up MongoDB replica sets and sharded clusters by reading the oplog data from your MongoDB deployment. 

MongoDB Cloud Manager Backup offers point in time recovery of MongoDB replica sets and a consistent snapshot of sharded clusters. 

MongoDB Cloud Manager achieves point in time recovery by storing oplog data so that it can create a restore for any moment in time in the last 24 hours for a particular replica set or sharded cluster. Sharded cluster snapshots are difficult to achieve with other MongoDB backup methods. 

To restore a MongoDB deployment from an MongoDB Cloud Manager Backup snapshot, you download a compressed archive of your MongoDB data files and distribute those files before restarting the mongod processes. 

To get started with MongoDB Cloud Manager Backup, sign up for MongoDB Cloud Manager$^{3}$. For documentation on MongoDB Cloud Manager, see the MongoDB Cloud Manager documentation$^{4}$. 

## Ops Manager Backup Software 

MongoDB Subscribers can install and run the same core software that powers MongoDB Cloud Manager Backup (page 186) on their own infrastructure. Ops Manager, an on-premise solution, has similar functionality to the cloud version and is available with Enterprise Advanced subscriptions. 

For more information about Ops Manager, see the MongoDB Enterprise Advanced 5 page and the Ops Manager Man- ual$^{6}$.
