Data Migration

Image Migration

You can use the image synchronization function of SWR to migrate images across regions.

For existing images in the image repository, you need to manually synchronize the images to the destination region. Images and image updates can be automatically synchronized between regions.

For details, see Configuring Automatic Image Synchronization Between Regions.

Cloud Storage Migration

If your cluster uses EVS disks or SFS file systems, you can use Cloud Backup and Recovery (CBR) for cross-region migration. CBR lets you back up ECSs, BMSs, disks, and on-premises VMware VMs. In case of a virus intrusion, accidental deletion, or software/hardware fault, data can be restored to any backup point.

For details, see Creating a Cloud Disk Backup or Creating an SFS Turbo Backup.

Cloud Database Migration

Data Replication Service (DRS) can be used to migrate cloud databases across regions. DRS provides multiple functions, including real-time migration, backup migration, real-time synchronization, data subscription, and real-time DR.
