Upgrade and Maintenance

IONOS Cloud updates and patches your In-Memory DB instance to achieve high standards of functionality and security. This includes minor patches for In-Memory DB and patches for the underlying operating system. Generally, these updates are unnoticeable and do not interrupt your operation. However, occasionally, IONOS restarts your In-Memory DB instance to allow the changes to take effect.

Prerequisites

• Prepare for a downtime during the version upgrade.

• Ensure the instance has enough available storage. While the upgrade is space-efficient (because it does not copy the data directory), some temporary data is written to the disk.

Note:

• Updates to a new minor version are always backward compatible. Such updates are done during the maintenance window with no additional actions from your end.

• Failure to configure persistence for a single instance might result in data loss.

Currently, IONOS DBaaS supports only minor version upgrades for In-Memory DB instances. Any changes that could cause service interruptions, such as version upgrades, are performed during a one-hour weekly maintenance window, which may result in brief connection interruptions. We recommend reconnecting to resume and complete any transactions that may have been affected during the maintenance window.

Note: Maintenance operations are initiated during the scheduled one-hour weekly maintenance window, but the duration may extend depending on the task. For example, tasks such as data replication may require additional time.

You can configure a maintenance window during the In-Memory DB instance creation using the same API request. For more information, see Create an In-Memory DB Instance. You can also configure one when you modify the existing In-Memory DB instance. For more information, see Modify an In-Memory DB Instance.

The following code schedules automatic maintenance every Monday at 16:30:59:

"maintenanceWindow":{
         "time":"16:30:59",
         "dayOfTheWeek":"Monday"
      },
