Volume Backup Service (VBS) provides snapshot-based data protection for Elastic Volume Service (EVS) disks. VBS secures your data, even if an EVS disk is faulty or encounters a logical error (for example, mis-deletion, hacker attacks, and virus infection).
Volume Backup Service (VBS) provides snapshot-based data protection for Elastic Volume Service (EVS) disks. VBS secures your data, even if an EVS disk is faulty or encounters a logical error (for example, mis-deletion, hacker attacks, and virus infection).
For details, see Unsubscribing from or Deleting an EVS Disk. Yearly/monthly disk: A yearly/monthly disk cannot be deleted, but you can unsubscribe from it if needed. For details, see Unsubscribing from or Deleting an EVS Disk. Parent topic: Billing
CSS uses EVS and local disks to store your indices. During cluster creation, you can specify the EVS disk type and specifications (the EVS disk size). EVS disk types include common I/O, high I/O, and ultra-high I/O.
In the list, select Elastic Volume Service (EVS) for Service Type. In the Resource Tag column, find the _sys_recycle_bin_volume:true tag, which identifies the EVS recycle bin bill.
If this still fails to meet your needs, it is recommended that you create RAID arrays with EVS disks or manage EVS disks using LVM. Parent topic: Capacity
Common Application Scenarios and Usage Instructions of SCSI EVS Disks BMSs support only SCSI EVS disks. Shared SCSI EVS disks: Shared SCSI EVS disks must be used together with a distributed file system or cluster software.
To check the supported regions, see the region information shown under "EVS Snapshots" in Function Overview. Calling Method For details, see Calling APIs.
Procedure Sign in to the EVS console. Choose Storage > Elastic Volume Service. The Elastic Volume Service page is displayed.
An EVS disk can be expanded either in the Available or In-use state. Expanding the disk capacity on the console enlarges the disk capacity, but you still need to log in to the server and extend the disk partitions and file systems to make that additional space usable.
For example, if an IAM user wants to query EVS disks using an API, the user must have been granted permissions that allow the evs:volumes:list action. Supported Actions EVS provides system-defined policies that can be directly used in IAM.
When you create a BMS, you can select one from the following storage types: Elastic Volume Service (EVS): provides EVS disks of different QoS configurations to meet performance requirements in various scenarios.

Differences Between Expanding an EVS Disk and Creating an EVS Disk The differences are as follows: Expanding an EVS disk is when you expand the capacity of an existing EVS disk. Some systems let you expand the capacity of EVS disks in use.
Handling Insufficient Disk Space on a Windows ECS Scenarios When the EVS disk space on a server is insufficient, the server running speed will be affected, which will further affect user experience.
The first snapshot is a full snapshot, which backs up all data (data blocks) on the EVS disk at the time of the snapshot. Subsequent snapshots are incremental snapshots, which back up only changed data blocks since the last snapshot. Parent topic: Snapshot
Yearly/Monthly data disks purchased on the EVS console have different expiration times as the server. They can be unsubscribed from separately. Parent topic: Billing
For more information about shared disks, see Managing Shared EVS Disks. Shared disks are a type of EVS disks that can be attached to multiple servers. A shared file system or cluster management system must be set up before you can properly use a shared disk.
Scenarios When the EVS disk space on a server is insufficient, the server running speed will be affected, which will further affect user experience.
Use a backup to create an EVS disk and associate the EVS disk with a server. For details, see Attaching a Non-Shared Disk or Attaching a Shared Disk. Then copy data in the data disk to the system disk. Parent topic: Restoration
