MONGODB COMPASS EXPORT DATABASE DRIVER

mongoimport and mongoexport do not reliably preserve all rich BSON data types because JSON can only represent a subset of the types supported by BSON. These backups may capture a small crucial set of data or a frequently modified section of data for extra insurance, or for ease of access. In contrast, use import and export tools to backup a small subset of your data or to move data to or from a third party system. The tools and operations discussed provide functionality that is useful in the context of providing some kinds of backups. When MongoDB reads infrequently used data, it can supplant more frequently accessed data, causing a deterioration in performance for the database’s regular workload.ĭata Import, Export, and Backup Operations – For resilient and non-disruptive backups, use a file system or block-level disk snapshot function, such as the methods described in the MongoDB Backup Methods document. Not only do these processes create traffic for a running database instance, they also force the database to read all data through memory.

Because these tools primarily operate by interacting with a running mongod instance, they can impact the performance of your running database. For disaster recovery protection and routine database backup operation, use full database instance backups.

For more complex data migration tasks, you may want to write your own import and export scripts using a client driver to interact with the database itself. The export and import tools are useful when you want to backup or export a portion of your data without capturing the state of the entire database, or for simple data ingestion cases.
