EVS is used to store DDS instance data. For details about EVS, see Elastic Volume Service User Guide. DDS instance backup data is stored in OBS and does not count towards your DDS storage quota.
Creating a VBS Backup You can create backups for your EVS disks to protect the disk data through the VBS console or the EVS console. Precautions An EVS disk can be backed up only when its status is Available or In-use.

Table 1 System-defined roles and policies supported by EVS Role/Policy Name Description Type Dependencies EVS FullAccess Full permissions for EVS. Users granted these permissions can create, attach, detach, query, and delete EVS resources, and expand capacity of EVS disks.
Overview What Is Elastic Volume Service? Elastic Volume Service (EVS) offers scalable block storage for ECSs.
RDS uses Elastic Volume Service (EVS) disks for storage. For details, see Elastic Volume Service Service Overview. The RDS backup data is stored in OBS and does not occupy the database storage space.

Table 1 API overview Type Subtype Description API EVS disk These APIs provide the functions, such as creating disks, deleting disks, and querying disk details. EVS snapshot An EVS snapshot is a complete copy or image of the disk data at a specific time point.
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 a BMS, a maximum of 60 EVS disks (1 system disk and 59 data disks) are supported. Only SCSI disks can be attached.
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.
An EVS disk can be expanded either in the Available or In-use state. Expanding the disk capacity on the management 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.
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.
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.
