API Overview

All SDRS APIs are extension APIs.

SDRS APIs allow you to use all SDRS functions.

**Table 1** API section description
Section	Description
Job	After a job, such as creating or deleting a protection group, creating or deleting a protected instance, or creating or deleting a replication pair, is issued, job_id is returned, based on which you can query the execution status of the job.
API Version	Used to query SDRS API version information.
Active-Active Domain	An active-active domain consists of the local storage device and remote storage device. Application servers can access data across data centers using an active-active domain.
Protection Group	Used to manage a group of servers to be replicated. A protection group is for servers in one VPC. If you have multiple VPCs, you need to create multiple protection groups.
Protected Instance	A protected instance consists of a server and its replicated server. One protected instance belongs to one protection group only. Therefore, the instance servers are in the same AZs where the protection group's production site and disaster recovery site reside.
Replication Pair	A replication pair consists of one disk and its replicated disk. One replication pair belongs to one protection group and can be attached to a protected instance in this group.
DR Drill	Disaster recovery drills are used to verify that disaster recovery site servers can take over services from production site servers after a failover.
Tag Management	Tags can be used to identify and classify protected instances.
Task Center	Task Center allows you to manage failed tasks of all protection groups or all failed tasks of a specified protection group.
Tenant Quota Management	Used to query tenant quota information.
