Can I Back Up and Restore My EVS Disk to a Different Region? How Do I Check the Backup Data of My Disk?
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Shared EVS disks do not have cluster management capabilities. You need to build a clustered system for data sharing, such as Windows MSCS, Veritas VCS, and Veritas CFS clusters. Parent topic: Sharing
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
EVS disks can process I/O requests concurrently, so 100% disk I/O usage does not mean that the disk encounters the performance bottleneck. For example, an EVS disk takes 0.1 second to process an I/O request and can process 10 I/O requests concurrently.
Delete or unsubscribe from the disk according to Unsubscribing from or Deleting an EVS Disk. Then, buy a new disk in the AZ where the server belongs. Data on the disk is required. Create a backup for the disk using the CBR service.
Does EVS Support Automatic Snapshot Creation? Can I Create Snapshots for Multiple Disks at a Time? How Is a Snapshot Created for My Disk? Why Can't I Roll Back My Disk Data from a Snapshot? Can I Roll Back Data from a Snapshot After Reinstalling the OS or Formatting a Disk?
Snapshot data can only be rolled back to source EVS disks. Rollback to a different disk is not possible. If the snapshot is being created, it cannot be used to roll back disk data.
For details about how to grant the KMS access rights, see EVS Disk Encryption in the Elastic Volume Service User Guide. 400 EVS.2059 invalid enterpriseProjectID Invalid enterprise project ID.
Yearly/Monthly data disks purchased on the EVS console have different expiration times as the server. They can be unsubscribed from separately. Parent topic: Deletion
For details, see Changing the EVS Disk Type. Method 2: Create a new disk from a disk backup to retain the disk data. The procedure is as follows: Create a backup for the disk. Figure 1 Create Backup Create a new disk from this backup.
Because an EVS data disk currently supports up to 32 TiB, use GPT if your disk size is greater than 2 TiB. If you change the partition style after the disk has been used, the data on the disk will be cleared.
The initial disk partitions are as follows: Procedure Access the EVS console and expand the system disk capacity to 140 GiB.
The value can be as follows: CURRENT: EVS custom APIs provide multiple versions. For APIs offering the same functions, you are recommended to use the v2 APIs. SUPPORTED: indicates an earlier version which is still supported.
EVS is a project-level service.
They have limited functions and cannot have EVS disks attached. The Attach button is grayed out. Go to Maximum Number of Disks That Can Be Attached to the Server Has Been Reached. Go to Check Whether the Disk Has Been Added to a Replication Pair.
For how to delete a disk, see Unsubscribing from or Deleting an EVS Disk. The following table lists the common usage scenarios and suggestions on pay-per-use disks.
