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.
Migrating from an old database
Some applications require a populated database to run properly. If you want to import your SQL dump, you can use several methods:
- Our WebGUI (PHP My Admin).
- Command line tool for MySQL administration.
- Any MySQL client such as MySQL Workbench.
If you need to import a very large dump, please send an email to support@clever-cloud.com.
Direct access
All our dedicated MySQL databases are served via a proxy. To reduce the latency you can bypass this proxy by generating direct hostname and port for the addon. You can do it by clicking the “Generate direct hostname and port” on the addon dashboard.
This action will add new environment variables to reach the addon without any proxy.
Encryption at rest
Encryption at rest is available on MySQL. You can have more information on the dedicated page
ProxySQL
ProxySQL is a tool that acts like a proxy between your application and your MySQL add-on. Instead of connecting to your MySQL add-on, you can connect to the local ProxySQL and it will forward all your requests to your MySQL add-on.
This allows you to let ProxySQL take care of some interesting features like connection pooling or leader / follower setup.
You can learn more about ProxySQL on the dedicated documentation page
Plans
🔑 Rights and permissions
Add-ons are managed services, meaning that users have standard access to the database (ALL privileges). Some operations like databases and users creation, as well as some settings modifications aren’t available by default. This ensures optimal performances and security for managed services as configured by Clever Cloud.
Authorized actions:
- Manage tables (create, delete…).
- Manage indexes.
If you think your system might require more advanced administrative access, contact Clever Cloud support to explain your use case, and we will work with you to find a solution.
Here is the list of actions that you won’t be able to perform:
- Database administration (for example you won’t be able to create new databases).
- Users administration (you won’t be able to create other users than the one handled with our control plane, i.e. the base owner and read-only users).
- Server configuration update.
- Plugins installation.
- Replica creation.
- Backup frequency or retention control.
Ask Clever Cloud support if you want to perform one of these actions.
