SDRS Advantages

Using the SDRS console, you can configure and manage server replication and perform failovers and drills.

You can set up disaster recovery for site servers from the production site to the disaster recovery site.

You can replicate servers from one AZ to another as required, reducing the costs and complexity for you to maintain another data center.

You can replicate all applications on the servers. The replication has no impact on the applications.

SDRS provides asynchronous replication for ECSs, and the recovery point object (RPO) is in seconds.

Normally, the recovery time objective (RTO) is within 30 minutes, which does not include the time spent on DNS configuration, security group configuration, or customer script execution.

Host-layer asynchronous replication ensures crash consistency between your production site and disaster recovery site. (SDRS only ensures crash consistency, not application consistency.)

By running disaster recovery drills, you can simulate recovery fault scenarios and formulate recovery plans. When a fault occurs, you can use the plans to recover services as quickly as possible.

If the production site fails, you can fail over to the disaster recovery site in just a few clicks (purchasing, deploying, and starting disaster recovery servers and attaching disks with the most current data). Services can be recovered with only a few configurations.
