MongoDB is an open source NoSQL document-oriented database. We provide these databases with daily backups and monitoring for both shared and dedicated plans.
The version currently installed by the add-on is :
- on shared plans (DEV) : MongoDB 4.0.3
- on newly created dedicated databases (plans XS Small Space and above) : MongoDB 4.0.3
About Free Databases
Free plans are recommended for test and development usage only. Using these databases in production is not recommended, because performance may vary depending on the global usage of the cluster. Therefore, before switching to production, consider upgrading to a dedicated database for better performance.
Important Note About Fair Use on Free Databases
Heavy usage of free databases may impact the shared cluster they rely upon. It will degrade performance of the other databases. To that extent, we set a soft limit of 15 operations/second. Going above the limit will expose your database to disconnection, would you not answer our notices.
Database Daily Backup and Retention
By default, Clever Cloud performs a free backup every day, with a retention of seven days. Retention and frequency can be customized for Premium customers.
Each backup can be found in the add-on dashboard in the web console, along with the credentials.
Database Migration Process
The migration process is pretty much the same for each of these cases:
- migrating from a Clever Cloud shared database to a dedicated one
- migrating from an external database to a Clever Cloud one
- migrating between Clever Cloud Databases
The process consists in three steps:
- First, perform a backup and download it, either with the Clever Cloud add-on dashboard or the
mongodumpcommand from your workstation.
mongorestore(a tool packaged with MongoDB)
- On your workstation, use the taylor-made
mongorestorecommand line located in your mongodb dashboard page (open the “Backup” panel and click on the “Restore” link to find the complete command line to perform the database import). If needed, change the
nsToflags, depending on what you actually want to do (importing this database in another, importing another to this one, …).
Encryption at rest
Encryption at rest is available on MongoDB. You can have more information on the dedicated page
