      Automatic Updates and Maintenance Windows


      Fully managed cloud database clusters built on top of Linode’s trusted and reliable platform.

      As part of the Managed Database service, the database cluster is updated regularly. This includes security updates and patches for the underlying operating system. These updates occur on a user-configurable maintenance window. By default, the maintenance window is set to start every week on Sunday at 20:00 UTC and lasts for 3 hours.

      Caution

      If your database cluster is configured with a single node, you will experience downtime during this maintenance window when any updates occur. It’s recommended that you adjust this window to match a time that will be the least disruptive for your application and users. You may also want to consider upgrading to a high availability plan to avoid any downtime due to maintenance.

      Note

      The database software is not updated automatically. To upgrade to a new version (such as from MySQL 5.7.30 or 8.0.25 to 8.0.26), consider deploying a new Managed Database with the version you wish to use. You can then
      migrate your databases
      from the original Managed Database cluster to the new one.

      View and Modify the Maintenance Window

      1. Log in to the
        Cloud Manager
        and select Databases from the left navigation menu.

      2. Select your Managed Database from the list. This opens the detail page for that database cluster.

      3. Navigate to the Settings tab.

      4. In the Maintenance Window section, you can view the day of the week the maintenance occurs, the time of day it starts, and if maintenance is performed on a weekly or monthly basis.

        • Day of Week: The day of the week that the maintenance will occur. The default is Sunday.
        • Time of Day (UTC): The time of day (in UTC) the maintenance window will start. The default is 20:00 UTC (8 PM). The maintenance window lasts for 3 hours.
        • Weekly or Monthly: Defines if the maintenance occurs once per week or once per month. The default is Weekly. If Monthly is selected, you can select if the maintenance should occur during the first, second, third, or fourth week of each month.
      5. To modify the maintenance window, make any changes you wish and click the Save Changes button.
