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.
Keep in mind that usage of direct access is a trade-off: when you migrate your addon, you will need to to generate hostname and port again so your application must update these environment while proxy usage changes nothing.
Encryption at rest
Encryption at rest is available on MySQL. You can have more information on the dedicated page
