Setting Instance Termination Protection
Last updated: 2025-12-01 19:04:19
Scenarios
In most cases, when you no longer need an instance, you can terminate the instance through the console or an API. To prevent accidental termination of the instance, you can enable the instance termination protection feature. If the feature is enabled, you cannot terminate the instance through the console or an API. If you confirm that the instance needs to be terminated, you can disable the feature first and then proceed with the termination.
You can enable instance termination protection to prevent accidental termination of the instances that contain your business data. This document introduces how to enable or disable instance termination protection through the console.
Feature Description
Instance termination protection is disabled by default for newly purchased and existing instances. You can enable it as needed.
After instance termination protection is enabled for the primary instance, the feature will be automatically enabled for all its associated read-only instances, disaster recovery instances, and read-only analysis engines, including both existing and newly purchased ones. You can disable instance termination protection individually for specific associated instances. For example, you can disable instance termination protection for a read-only instance.
After instance termination protection is disabled for the primary instance, the feature will be automatically disabled for all its associated read-only instances, disaster recovery instances, and read-only analysis engines.
When instance termination protection is disabled for the primary instance, you can independently enable the feature for the associated read-only instances, disaster recovery instances, or read-only analysis engines. When the feature is independently enabled for these instances, it is not automatically enabled for the primary instance.
Must-Knows
Instance termination protection does not apply to system-level termination, such as the termination of pay-as-you-go instances that are shut down due to overdue payments and the termination of yearly/monthly subscription instances that have expired and remained in the recycle bin for more than 7 days.
Fee Description
Currently, the feature is free of charge.
Supported Architectures
The feature is supported for TencentDB for MySQL instances with single-node, two-node, three-node, and Cluster Edition architectures, as well as the read-only analysis engine.
Feature Status Description
After instance termination protection is enabled, the status of related instances in the instance list and instance details page will become Termination Protection Enabled. You can quickly determine whether this feature is enabled by this status.
After instance termination protection is enabled, all feature buttons associated with instance termination for the instance will be grayed out and unavailable for clicking.
