The "Take Offline or Restore Recycle Bin Instances" feature is used to manage database instances that have been returned or destroyed and are within the retention period in the recycle bin. This operation provides you with an important data security buffer to rectify accidental operations or perform data restoration.
If you accidentally return a yearly/monthly subscription instance or terminate a pay-as-you-go instance, you can fully restore it using the restoration feature within the recycle bin retention period. After the instance is restored, its configuration, data, and connection address will remain unchanged, and business access can resume immediately.
Actively and thoroughly destroy data (Decommission Instance)
If you confirm that an instance in the recycle bin and its data are no longer needed at all, you can actively perform the "decommission" operation. This operation will immediately and permanently delete the instance and all its data, release the resources it occupies, and it cannot be restored. It applies to scenarios that require strict implementation of data cleanup policies or immediate release of resources.
Recycle Bin Retention Period Description
After an instance is returned, terminated, or suspended due to overdue payments, it will go through the following lifecycle stages in sequence. During the recycle bin and backup retention periods, you can choose to restore data. Data not restored after the retention period expires will be permanently deleted. The recycle bin retention periods for various scenarios are as follows:
Yearly/monthly subscription instances: After the renewal grace period (7 days) is exceeded or the instance is actively returned, it is placed in the recycle bin and retained for 7 days.
Pay-as-you-go instances (overdue payments): After being automatically suspended for overdue payments exceeding 24 hours, they are placed in the recycle bin and retained for 7 days.
Pay-as-you-go instances (actively terminated): After being actively terminated, they are placed in the recycle bin and retained for only 2 hours.
Duration
Handling Mechanism
Within the Recycle Bin Retention Period
Cloud database resources become unavailable after shutdown. The instances are isolated in the recycle bin.
Restorable: The instance can be fully restored using the restoration feature.
Decommissionable: Directly decommission the instance immediately to permanently destroy data.
At the end of the retention period, cloud database resources in the recycle bin are automatically cleared, and instances can no longer be manually restored.
Note:
After a cloud database is shut down, you will be notified of the service release time via voice call (the actual notification method is subject to your subscription configuration in the Message Center).
After the Recycle Bin Retention Period
Cloud database instances are cleared from the recycle bin, and instance backups are stored in the backend for 8 days. To restore instances, contact Tencent Cloud engineers.
After being stored in the backend for 8 days, cloud database resources are permanently terminated, all data is deleted, and cannot be recovered.
Prerequisites
The instance has been released and isolated in the recycle bin.
2. On the left sidebar, select Tencent Cloud Distributed Cache > Recycle Bin.
3. Above the Instance List page on the right, select the target region.
4. On the Recycle Bin page on the right, you can see the list of instances in the recycle bin, all of which are in the Isolated status.
5. In the instance list in the recycle bin, find the target instance and click Start Up in the Operation column.
6. Confirm the instance information and restore it.
If the instance is a yearly/monthly subscription instance, in the Renew Selected Instances dialog box, you need to perform the following operations and click OK to restore it.
Click View Details to confirm the instance information.
In Renewal Period, select the duration of the instance renewal by full month or full year.
Next to Total Fees, confirm the total amount for the instance renewal.
If the instance is pay-as-you-go, confirm the instance information and click OK in the Start Instance window to restore it.
Note:
As Tencent Cloud Distributed Cache is an in-memory database, to use the batch instance restoration feature, submit a ticket for application.
1. In the instance list in the recycle bin, select all instances that require restoration.
2. Click Renew above the list. In the Renew Selected Instances dialog box, perform the following operations.
Click View Details to confirm the instance information.
In Renewal Period, select the duration of the instance renewal by full month or full year.
Next to Total Fees, confirm the total amount for the instance renewal.
3. Click OK, on the Confirm the Following Product Information page, confirm the product list and verify the renewal amount. Click Submit Order, select a payment method, and click Next. After successful payment, the renewal is completed. The instance will be automatically unisolated and removed from the recycle bin. In the left sidebar, select Instance List to view the unisolated and restored instance in the instance list.
2. In the left sidebar, choose Distributed Cache (Redis-compatible) > Recycle Bin.
3. Above the Instance List page on the right, select the target region.
4. You can view the list of instances in the recycle bin, all of which are in the Isolated state. Locate the instance to be shut down and click Eliminate Now in its Operation column.
