SDRS Usage Restrictions
Before using SDRS, learn about the constraints listed in the following tables.

Constraints on EVS disks:
|
|
Storage |
Only servers using EVS or DSS disks are supported. |
Application |
Storage-based synchronous replication ensures disk data consistency but does not guarantee application data consistency. If your applications support crash consistency, you can run and replicate applications. |
Deployment model |
VPC migration: Servers at the production site and those at the disaster recovery site are in the same VPC. NIC migration and multiple NICs are supported for each server. |
Service interconnection |
Tag Management Service (TMS) is supported only via API. |
Backup and restore |
Only servers at the production site can be backed up and restored. Servers at the disaster recovery site can only be backed up. |
If the production site AZ becomes faulty, you can run a disaster recovery drill to recovery the services on servers.
