The document discusses modern data backup and recovery strategies for MongoDB deployments moving from on-premises to public cloud environments. It describes the evolution of backup architectures from complex on-premises solutions utilizing multiple agents and load balancers to take backups, to more simplified future architectures that leverage features like WiredTiger checkpoints to backup directly to object storage. It also outlines the different backup options available with MongoDB Atlas in the cloud, including continuous backups with point-in-time recovery, queryable backups for granular restores, and utilizing native cloud provider snapshots.
