As a huawei cloud information giant, Reading Knowledge Cloud is good at presenting complex information in a diversified way. There is always a picture (cloud map), profound and simple blog (cloud class) or short video (cloud vision hall) that can make you quickly start huawei cloud. Click here for more highlights.
Abstract: With cloud backup, you can implement same-availability migration, cross-availability migration, cross-region migration, cross-account migration and even cross-cloud migration. Can’t believe it? Here’s a look with xiaobian
Lesson 64 The original cloud backup service can do more than just back up data? , author: Yun Xiaomeng.
Many people prefer to use command line copy for data migration of servers, disks, or file systems. This approach may seem convenient, but in fact there is a hidden risk of data loss.
Can’t think of a quick, easy and safe way? Have you ever thought that cloud backup might help you?
Cloud Backup – Doesn’t that sound like backing up your data? Data can be recovered in the event of data loss. But I don’t need a backup function
No nono! The function of cloud backup is very powerful, although the main occupation is backup and recovery, but in fact, there is a good performance in data migration.
With cloud backup, you can migrate with availability, across availability, across regions, across accounts, and even across clouds.
Can’t believe it? Here’s a look with xiaobian
Migrate with availability zones
If you want to quickly have two identical disks, servers, or filesystems in one available area, or just switch disks and servers, you can quickly have fun in two steps
1. Back up the target resource. Buy a repository to bind resources, and then backup it
2. Use the backup to create a disk, an image, a server, and a file system. Ensure that the available zone is the same as the current available zone. The data in the new resource is the same as at the backup point in time.
In this way, you can have two resources in the same usable area
Migration across availability zones
Suddenly, I find that the disk and file system I bought are not in the same available area as the server. As a result, the latency is greatly increased and the usage experience is affected. What should I do?
Of course, you can use cloud backup to quickly create a resource of the same type across the available area, directly and smoothly switch
The procedure is the same as that for migrating availability zones. When creating resources, you only need to select other availability zones ~
Transregional migration
Want to move resources between regions? Server area B of area A also want to own?
How to use cloud server backup to migrate cloud server data across regions?
However, only the data of the server and file system can be migrated
Cross-account Migration
Xiao Ming’s happiness xiao Mei also want to have? Try the shared backup feature of cloud backup.
Cloud backup supports backup sharing between different accounts in the same area, which makes it possible to migrate resources between different accounts in the same area.
Currently, only server backup and disk backup can be shared.
1. Back up the target resource. Buy a repository to bind resources, and then backup it
2. Share the backup file with other accounts. As long as the other party accepts the backup, you can use the backup to create a server or disk
Across the cloud migration
Cloud backup Synchronizes offline backup data of OceanStor Dorado storage arrays and VMware VMS.
When an event such as a data center disaster or an optical fiber network fault occurs, you can quickly create a cloud server using backup data on the public cloud to shorten service interruption time. In addition, backup data can be copied to other regions as required to implement rapid service deployment on the cloud.
This operation is relatively difficult and will not be described here. If you are interested, you can search for “hybrid cloud backup” on the official website of Huawei Cloud.
conclusion
Data migration can be implemented in a number of ways, and this article is only introduced from the perspective of cloud backup. Those who are interested in other methods can check out other cloud lessons
After reading this article is not feel to have a cloud backup has a variety of happiness ~ do not hurry to buy try?
