mongodump is a tool bundled with MongoDB that performs a backup of the data in MongoDB, producing consistent snapshots of the data by dumping the oplog, but it can exert too much load to be a truly scalable solution and may not be suitable for larger systems. `Copying the underlying files using standard file system copy tools or creating a snapshot of the entire file system can provide more efficient backups, but it requires ongoing maintenance and devops expertise to ensure consistency across multiple replica sets. `MongoDB Management Service (MMS) provides continuous online backup for MongoDB as a fully managed service, offering flexibility in configuration, minimal performance impact, and availability on both cloud-based and on-prem software platforms.
