After confirming the information, click on the "Submit" button and wait for the completion to be completed in the disaster recovery management platform.
After configuring the disaster recovery platform on Huawei Cloud, you can proceed to [1. Configure the production platform] or proceed to [4. Perform disaster recovery operations]
4. Perform Disaster Recovery Operations
When the hosts to be protected against disasters have already been added, select the hosts and click on the "Next" button to go to the disaster recovery configuration page: 
4.1. Disaster Recovery Configuration
On the Hops DR page, select the hosts to be protected against disasters, click on the "Setup DR" button, select "Object Storage Recovery" and follow the configuration steps: 
Disaster recovery configuration step 1: Specify DR Platform; Select the configuration information of the disaster recovery platform where the disaster recovery host is located, and click the "Next" button.
If the disaster recovery platform information is empty, it means that no disaster recovery platform has been added yet. You need to configure the disaster recovery recovery operation before proceeding with the subsequent operations.
Choose "Object Storage" for the select storage type and select the configured object storage and recovery platform. 
Disaster recovery configuration step 2: Computing Resource Configuration; Select the flavor and OS type for the disaster recovery host on the target disaster recovery platform. Once configured, click on the "Next" button. 
Disaster recovery configuration step 3: Specify Volume Type; Choose the volume type used by the disaster recovery host on the target disaster recovery platform. If there are multiple volumes, you can configure them separately for system and data volumes. Once configured, click the "Next" button. 
Select the disk for booting. If the first disk in your original system is not designated for booting, you must specify the boot disk here, or it may result in startup failure.
Note: In block storage mode, due to limitations in the cloud platform API interface, once data synchronization is completed, the option for the boot disk cannot be changed. Before initiating synchronization, please reconfirm the selected disk for booting. If chosen incorrectly, you will need to clear data and initiate synchronization again. Exercise caution to ensure the accurate selection of the boot disk and avoid unnecessary re-synchronization steps.
Disaster recovery configuration step 4: Network Congfiguration; Select the VPC network, Subnet, and whether to specify an IP address at startup, configure a public IP, and security group for the disaster recovery host on the target disaster recovery platform. Once configured, click the "Next" button.
VPC networks and Subnets need to be created in advance under your Huawei Cloud account.
Disaster recovery configuration step 5: Associat Policy; Associate the corresponding disaster recovery policy with the standby host (association can be skipped for now). If there is no policy, you can create a new one. After completion, click the "Submit" button.
Before starting the policy configuration, the hosts that have already been configured will automatically enter the "Start DR" phase.
After completing the disaster recovery configuration, you can still choose to modify the disaster recovery configuration for the host in the "Action" section.
4.2. Data Synchronization (Full / Incremental)
In the "Start DR" step, you can select one or more hosts to be protected against disasters, and click on the "Sync" button to synchronize data:
Confirm the disaster recovery hosts that need to be synchronized and click on the "Submit" button:
For the first synchronization, full data will be synchronized. For subsequent synchronizations, incremental data will be synchronized. You can also select run full synchronization, which means that all data will be synchronized during this synchronization.
Wait for the data synchronization of the disaster recovery hosts to complete.
4.3. DR Drill / DR Takeover
After the data synchronization (snapshot synchronization) is completed, select the host and click on the "Drill" / "Takeover" button accordingly:
The "Drill" / "Takeover" functions are consistent, these functions indicate starting the disaster recovery host on the disaster recovery platform, and relevant verification and takeover work can be performed after the start.
Select the snapshot time point when starting the disaster recovery hosts and click on the "Submit" button to start the host instance.
Note: This action will start an instance on the Huawei platform according to the disaster recovery parameters set for this disaster recovery host. This instance is a host recovered to the cloud. The snapshot time point is generated each time data is synchronized and is used for selection during startup. (The number of reserved snapshot time points can be configured as needed.)
4.4. View Disaster Recovery Result
After the disaster recovery host is started, if the host startup status displays the relevant configuration information of the host on the disaster recovery platform, it means that the disaster recovery drill/disaster recovery takeover was successful. You can log in to Huawei Cloud to view the running status of the disaster recovery host:
4.5. Clean Up Verification Host
Select the host that needs to be "Clean Up Verification Host", and in the "Action" section, click on the "Clean Up Verification Host" option. Wait for the cleaning process to complete.
5. Host Group Disaster Recovery
Host group disaster recovery is mainly applicable to groups of disaster recovery host resources with similar attributes and requirements. These groups can be based on business units or other dimensions of resource sets. All operational configurations are done at the host group level. This includes setting up host group synchronization strategies, where all disaster recovery host data synchronization commands within the group are issued simultaneously to ensure that all host data in the host group remains consistent at the underlying level.
When adding a disaster recovery host to host group disaster recovery, it is necessary to ensure that the single host disaster recovery configuration is completed before it can be added to the disaster recovery host group. Otherwise, it cannot be directly added to the host group disaster recovery.
5.1 Create Host Group
Go to the "Group DR" on the left menu bar and then click the "+Add" button:
Step1: Basic Info
Configure basic information for the Host Group, including "Name" and "Description." You can add information in these two sections according to your needs. Then, click the "Next" button.
Step2: Select Hosts
Select the disaster recovery host resources that have completed the disaster recovery configuration on the left side. Click the "Add Resource" button to include the corresponding disaster recovery hosts in the resource group. Then, click the "Next" button.
Step3: Associate Policy
Choose the policy used by the resource group. If a synchronization policy has been created in advance, you can select it directly. If not, click the "Create Policy" button to create a new disaster recovery policy.
Step4: Boot Sequence
Adjust the startup sequence of the host resources in the associated resources on the left, and click "Finish" after confirmation. 
5.2. Modify Host Group
Click the "Action" button after selecting the resource group to modify the Basic Info, Select Hosts, Associate Policy, and Boot Sequence of the resource group.
5.3. Delete Host Group
Go to [Group DR] and click the on “Delete Host group” button : Check the resource group, and click the "Delete Resource Group" button to perform the operation of deleting the resource group.
According to the prompt for host group deletion, select the relevant configuration options, enter the character "Yes" to confirm deletion, then click the [Submit] button to complete deletion.
Tips
Notes:
1: This operation only deletes the host group, and the resources in the host group will be retained. The disaster recovery hosts in the host group will still be displayed separately in the host disaster recovery, and the disaster recovery operation can still be performed on a single disaster recovery host, and the data that has been synchronized will not be cleared from the disaster recovery platform.
2: This operation not only deletes the host group, but also the resources in the host group. The disaster recovery hosts in the host group will be directly cleared from the disaster recovery platform, and all synchronized data will be cleared.
3: (Not recommended) I confirm that I want to force clean up resources, which may cause residual resources (only used when cleaning fails). [Use in special scenarios only such as disaster recovery hosts in the host group lose contact or cleaning fails. This option will directly clear the records without initiating a call request.]
5.4. Host Group – Data Synchronization
Select the configured host group, click the “Sync” button, and then the “Submit” button to perform data synchronization. You can also automatically perform data synchronization according to the configured Host Group Policy Management.
For the disaster recovery hosts that are first added to the host group, it is necessary to perform data synchronization even if the data synchronization operation has been performed in the Host Disaster Recovery during the disaster recovery process.
The synchronization policy of the host group will automatically execute data synchronization tasks according to policy settings.
5.5. Host Group - DR Drill / Takeover
Wait for data synchronization to complete (synchronization snapshot completed), check the host group that needs to be disaster recovery drilled/taken over, then click on the "Drill" / "Takeover" button.
Tips
Note: For disaster recovery hosts that are first added to the host group, it is necessary to perform data synchronization operation, otherwise it will not be possible to perform disaster recovery drill/takeover even if the disaster recovery hosts in the host group have already performed data synchronization operation during Host Disaster Recovery.
In the pop-up box, select the synchronization time point snapshot copy, after confirming that the information is correct, click the "Submit" button.
The synchronization time point records the recoverable data time point for each snapshot copy generated after each data synchronization is completed.
When the host group status showing disaster recovery drill / takeover is completed, you can log in to the disaster recovery platform for drill and takeover operations.
5.6. Host Group - Clean Up Validation Resources
Check the resource group that needs to clean up and verify resources, click the "Action" button, and select the "Clean Up Validation Resources" button.
This operation means that the disaster recovery hosts in the host group that have already performed disaster recovery drill / takeover and the disaster recovery host instances generated on the disaster recovery platform will be deleted. This action prevents the risk of manual operation of deleting instances on the disaster recovery platform.
Warning
Note: If the disaster recovery host restored on the disaster recovery platform has taken over the business, do not perform this operation, as this operation will directly delete the instances generated on the disaster recovery platform.
After confirming that the resources to be cleaned on the disaster recovery platform are accurate, enter the character "Yes" in the input box to confirm and click the “Submit” button.
