# MongoDB Features

MongoDB is a source-available cross-platform document-oriented database program for high-volume storage. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

- **Daily point-in-time backups**. Full cluster backups are taken daily and write-ahead-logs are maintained to allow you to restore to any point-in-time within the previous seven days.
- **High availability with automated failover**. In the event of a failure, managed databases with a standby node automatically switch data handling to the standby node to prevent unplanned downtime. [Learn more about high availability for managed databases](https://docs.digitalocean.com/products/databases/index.html.md#high-availability).
- **Cluster metrics and alerting**. Cluster metrics visualizations help you monitor the performance of the nodes in a database cluster, like resource usage, to guide capacity planning and optimization. Alert policies notify you when a metric rises above or falls below a threshold you set, like high CPU or low memory.
