Constraints on EVS disks: Disks used to create replication pairs cannot be deleted, and the disk snapshot cannot be used to roll back data. Storage Only servers using EVS or DSS disks are supported.
You pay only for the disaster recovery site EVS disks and the Object Storage Service (OBS) buckets used. Simple deployment: Agent can be installed online without interrupting production services. The deployment is simple and fast.
Storage Disaster Recovery Service (SDRS) provides DR services for many cloud services, including Elastic Cloud Server (ECS), Elastic Volume Service (EVS), and Dedicated Distributed Storage Service (DSS).
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.
SCSI Small Computer System Interface (SCSI) is another EVS device type. SCSI EVS disks support transparent SCSI command transmission and allow the server OS to directly access the underlying storage media.
Quotas can limit the number or amount of resources available to users, such as the maximum number of ECS or EVS disks that can be created. If the existing resource quota cannot meet your service requirements, you can apply for a higher quota. How Do I View My Quotas?
ECS Creating Protected Instances Use EVS disks to create replication pairs in asynchronous replication. EVS Creating Protected Instances Create a disaster recovery network on the cloud for asynchronous replication.
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.
The following two options are available: EVS DSS If you select DSS for DR Site Disk, Storage Pool is mandatory. EVS Storage Pool If you select EVS for DR Site Disk, Storage Pool is not required.
If there are no disaster recovery site servers, EVS disks will be deleted.
For details about how to detach a disk online, see Disk > Detaching an EVS Disk from a Running ECS in the Elastic Cloud Server User Guide. Procedure Log in to the management console. Click Service List and choose Storage > Storage Disaster Recovery Service.

EVS Storage Pool If you select EVS for DR Site Disk, Storage Pool is not required. If you select DSS for DR Site Disk, Storage Pool is mandatory. dss-01 Protected Instance Name Mandatory Enter a protected instance name, which is used for instance classification and search.
Your account has sufficient resource quotas, including ECS, EVS, and VPC quotas. The RTO of SDRS asynchronous replication does not include the time that you spent on manual configuration and service configuration. Figure 1 RPO and RTO Parent topic: Common Problems

Billing Modes Billing for SDRS is for the service only and does not cover protected resources such as ECSs and EVS disks. Billing modes of production site resources purchased by you will not change.
