Amazon DocumentDB is a fully managed proprietary NoSQL database service that supports document data structures and MongoDB workloads. DocumentDB, like any other service, is not immune to operational usage issues and accidental deletions. Therefore, customers need to have a backup solution for business continuity and compliance needs.
You can use Metallic software to protect Amazon DocumentDB clusters across multiple accounts and regions. Metallic integrates with AWS native snapshots to protect Amazon DocumentDB clusters.
Note: Metallic takes native AWS snapshots of Amazon DocumentDB. You cannot create a backup copy.
