Cloud Disaster Recovery Service

Cloud DRaaS (Disaster Recovery as a Service) is a cloud service for rapid disaster recovery of virtual servers in the LanCloud backup data center in case of partial or complete failure of the customer's primary data center.

The Cloud DRaaS service is based on Veeam Cloud Connect and Backup & Replication. The service continuously replicates virtual servers from the customer's local data center to the LanCloud data center. In case of a failure in the local data center, the customer can launch all or part of the virtual servers in the LanCloud cloud data center within minutes. All virtual servers remain accessible via the network thanks to an automatically created L2 VPN tunnel.

The main difference between Cloud DRaaS and Cloud Backup (BaaS) is the minimal possible recovery time - RTO (Recovery Time Objective) and minimal data loss - RPO (Recovery Point Objective). Using standard backup services, recovery time can take hours, days, or even weeks depending on data volume, causing business downtime and financial losses. With Cloud DRaaS, these times are reduced to just a few minutes. Even in the event of any disaster affecting the primary data center, business operations can resume in the LanCloud backup data center with up-to-date data in under 15 minutes.

Cloud DRaaS can be used alongside Cloud Backup, saving on Veeam Backup & Replication licensing. If you already have Veeam licenses, you can use them to reduce service costs.

Main advantages of Cloud DRaaS:

Disaster-resilient protection for your data center
Recovery of virtual servers in less than 15 minutes
Data freshness within 15 minutes prior to failure
100% resource allocation guarantee at 30% of the cost
Pay-as-you-go with per-minute billing
Ability to failback when restoring the primary data center
Full Microsoft Hyper-V support
Option to use your own Veeam licenses

Cloud DRaaS Cost Calculator

To calculate the cost of Cloud DRaaS, select the number of virtual servers to replicate to the cloud and specify the corresponding number of Veeam Cloud Connect Replication licenses. If you do not have your own Veeam Backup & Replication licenses, you can rent them from us by selecting the required quantity in the calculator. It is recommended to use the same edition for all virtual servers: Standard, Enterprise, or Enterprise Plus. Standard is sufficient for most scenarios; Enterprise is recommended for high-load solutions with limited Internet bandwidth due to the WAN accelerator, which compresses traffic and speeds up data transfer. Enterprise Plus is mainly required if you need advanced backup features in addition to disaster recovery. Detailed edition comparison can be found here.

Next, choose the amount of computing resources (CPU cores, memory, disks, external IP addresses) to reserve for immediate disaster recovery. These resources are always available for testing disaster recovery. Reserved resource prices in the calculator are 30% of the real cost. During a planned or emergency launch, the cost is 100% of the resource price, billed per minute while servers are running in LanCloud.

To save costs, you can opt not to reserve resources. In this case, virtual servers can still be replicated to LanCloud, but emergency launch requires contacting support to allocate resources. LanCloud cannot guarantee 100% availability in this scenario. When resources are reserved, LanCloud guarantees 100% availability, allowing customers to launch servers without technical support intervention.
