Disaster Recovery Replication

1.Description of the Technology

Replication is a process of continuous creation of an identical standby copy (called replica) of the primary virtual server in another data center located at a safe distance of at least 100 km. The replication can be activated in one click, whereupon you do not do any activities, in the background the system automatically runs all the complex operations. The replication does not affect the virtual server performance nor it slows down the connection, as it uses independent dedicated resources.

The replica and the primary server are kept in sync by constant data transfer between them. The transfer is carried over geo redundant ultra high speed lines (Nx100Gbps), to ensure creation of replica in real time, even when the primary server undergoes intensive writes on super fast NVMe disks and even when one of the redundant lines is down.

In the case of an incident in the primary data center, the replica can be started and continue to run from the disaster recovery data center, without the need of preparing new servers and related infrastructure, as well as restoring from backup copies (if you made a backup copy at all).

Please note that replication is not a substitute for backup. If there is an incident at the primary data center and the current state of the virtual server is "faulty", as in the case where the operating system is already running with errors or certain applications are misconfigured, the replica will contain only the last "faulty" condition of the virtual server. For such cases you can protect the data by making snapshots or activate the Automatic Backups feature, which will enable you to restore the virtual server back to an earlier "good" version.

2.Activate / Deactivate

Sign into the My Interspace control panel, open the service related to the server, then open the Disaster Recovery Replication tab.

Toggle to Yes the Activate replication option field and click save. The replication starts immediately.

Toggle to No the Activate replication option field and click save, to terminate the replication.


Sign into the My Interspace control panel, open the service related to the server, then open the Disaster Recovery Replication tab.

Here you can view relevant information such as current replication status, primary / secondary server, last synchronization.

Elastic Cloud VPS
Elastic Cloud VPS is a virtual machine powered by advanced cloud and networking technologies, offering significant advantages over traditional VPS hosting at an unbeatable price to performance ratio. Deploy OS and apps in just 1 min. Dynamically add or remove features. One click automatic backups, snapshots and disaster recovery replica, stored in a remote data center at a safe distance. New gen of AMD EPYC CPUs, ultra fast NVMe disks, dedicated connections and free private net.
Cloud VPN PointConnect
Cloud VPN enables individual computers to securely connect to your cloud private network from anywhere in the world, by encrypting data as it travels over the Internet. Once connected, they can access any of your virtual or dedicated servers, as well as metro Ethernet endpoints using their private IPs. It's perfect for providers of CRM, ERP and services alike, who want to provide secure access to their apps over the Internet.
Cloud NАТ Gateway
Cloud NAT Gateway enables inbound and outbound connections over the Internet, for your virtual servers that have only private IP addresses. The servers access the Internet by routing the traffic through the NAT gateway. Optionally, the servers can receive inbound connections from the Internet using the port forwarding feature. This solution helps you avoid costs for public IPs, but even more than that. It enables backend applications to access the Internet, as well as public access to your web apps placed behind NAT.
