Industry: data security and reliability are very important in the industry. Data disaster preparedness solutions can help organizations back up and restore important data and ensure business continuity and customer asset security.

Data disaster recovery solutions can also be applied to a variety of industries and scenarios to help enterprises and institutions back up and restore important data and ensure business continuity and data security.

Third, Huawei Cloud data disaster recovery solution

Cloud backup (CBR): cloud backup provides easy-to-use backup services for cloud servers, cloud disks, SFS Turbo, file directories, cloud desktops, etc. It can restore data to any backup point in case of virus invasion, human error deletion, software failure and other scenarios.

When an event such as artificial deletion or virus invasion occurs, you can quickly restore the data to the backup point in time, and you can also create an image through the backup of the whole machine and quickly copy one or more CVMs with the same configuration as the existing CVM. The time for issuing servers can be reduced to the level of minutes, thus achieving rapid batch deployment and migration of the business.

Cloud disaster recovery: Huawei's cloud disaster recovery solution covers three disaster recovery scenarios: cross-AZ disaster recovery, cross-Region disaster recovery, and two places and three centers on the cloud, and take the lead in launching the storage disaster recovery service SDRS of storage synchronous replication technology, so that the cross-AZ disaster recovery RPO is equal to 0. Cross-Region disaster recovery and two-place and three-center disaster recovery services can meet the demands of enterprises for cross-regional disaster recovery scenarios, and effectively prevent accidents caused by earthquakes, typhoons, tsunamis and other natural disasters. It is suitable for all kinds of enterprises to deploy both the new IT system and the disaster recovery system on the cloud while paying attention to the deployment cost of the IT system, or when the existing IT system is deployed on the cloud, and to ensure reliability, the disaster recovery system needs to be deployed on the same public cloud.

Backup on cloud: backup on cloud refers to the process of backing up data to cloud storage. It supports a variety of backup methods, including file backup, database backup, virtual machine backup, etc., and provides flexible backup planning and recovery options. Through Huawei Cloud backup on Cloud solution, users can easily back up data to the cloud and quickly recover data when needed, improving the security and availability of data.

Hybrid cloud disaster recovery: customers'IT systems (that is, applications and databases) are deployed in local data centers, while disaster recovery systems are deployed in Huawei public cloud. It is suitable for all kinds of enterprises to ensure normal business through switching when a failure occurs in order to improve the reliability of databases and applications.

Its advantage is that it combines the advantages of local environment and cloud environment to provide higher availability, flexibility and scalability. It can dynamically adjust resources and capacity according to business needs and disaster situations to achieve disaster recovery and business continuity. In addition, hybrid cloud disaster recovery can reduce cost and complexity, and improve the security and reliability of data.

Consistent backup is more assured: based on the consistent snapshot technology of multiple cloud disks, the crash consistent backup of CVM is realized.

Reliability up to 11 9s: backup data persistence up to 11 9s, close to permanent storage

Backup strategy is more flexible: support manual / automatic backup, can set automatic backup strategy, periodic automatic backup, and can turn on periodic full backup for higher reliability.

Fifth, Huawei cloud backup experience

5.1 backup to the cloud

Activate the service

Hybrid cloud backup repository:

Backup object: backup data of offline VMware virtual machines

Recommended scenario: you need to manage the backup data of the cloud server on the cloud, and use the cloud data to restore the server on the cloud, etc.

Product experience

Backup on the cloud is a way to store data backups in the cloud, and it provides many useful features. First of all, VM backup on the cloud is a way to back up virtual machines. For more information, please refer to the instruction manual. By uploading virtual machine backups to the cloud, users can easily restore the state of the virtual machine in response to unexpected failures or data loss. Secondly, backup Shangyun also provides debugging capabilities by invoking services through API and SDK. This means that developers can use the API and SDK of cloud backup services to customize and integrate backup functions. They can call the corresponding interface according to their own needs to realize automatic backup, monitoring and management.

The above is to call the Api API of Cloud add Resources (AddVaultResource) on backup, in which you need to enter the AK / SK value generated by the platform, and you need to specify the user Token information. Call the IAM service to obtain the value of X-Subject-Token in the response message header. The service interface needs to enter the project ID and the repository ID for call processing. Its main function is to manage the backup of Huawei cloud backup service, including creation, query, deletion and other operations.

Product advantage

Affordable: backup on the cloud is economical and affordable, while eliminating the maintenance cost of storage equipment such as traditional physical belt library

Reliable security: backup data persistence up to 11 9; support client encryption, transmission encryption, storage encryption to ensure data security

5.2 backup on the cloud

Activate the service

Backup object: all cloud disks (system disk and data disk) in the server

Recommended scenario: the entire CVM needs to be protected

Product experience

The CVM repository provides rich development interfaces, such as API and SDK, so that users can call services programmatically for debugging and management. Through API and SDK, users can automate the creation, monitoring and recovery of backup tasks, and improve the efficiency and flexibility of backup management. At the same time, API and SDK can also be integrated with other cloud services to achieve cross-platform and cross-regional transmission and storage of backup data, further enhancing data availability and reliability.

The figure above calls the copy backup (CopyBackup) Api API for cloud backup. This API needs to specify the Token information of the user, as well as the region where the current API is open and two necessary parameters: the replicated backup ID and the project ID. If it does not meet the requirements, you will be prompted to call the relevant API in accordance with the parameters. After the API call is completed, the response volume data is returned to the user:

The figure above shows that before creating a backup on the cloud, you need to find the corresponding repository of the CVM, select the server that needs to be backed up, enter the repository, bind the target server, and perform the backup operation to back up the target server.

Product advantage
