Minimizing Business Downtime with Alibaba Cloud Hybrid Disaster Recovery Solution

  1. Disaster recovery replication: When the accounting system was running, the engineer started disaster recovery replication with one click to quickly and fully replicate all the data on the disk, including the operating system (OS), applications, and files, to a cloud disk on Alibaba Cloud. The replication speed was limited to 35 Mbit/s to ensure that the business was not affected. After the full replication was completed, the system entered the real-time replication status and the RPO reached about 5 seconds.
  2. Business downtime: The field engineer pulled out the server hard disk, causing the server to go down and business to be interrupted. Within a few seconds, the monitoring system detected that services were unavailable and the client no longer performed any reimbursement tasks.
  3. Disaster recovery: The engineer initiated on-cloud disaster recovery. HDR created an Elastic Compute Service (ECS) instance on Alibaba Cloud that had the same configuration as the off-cloud server, attached the cloud disk that contained the replicated disk data of the local server to the ECS instance, and started the instance. When HDR detected that services on the ECS instance had been started, it switched to Domain Name System (DNS). Within 1.5 minutes, the business resumed operation on the cloud and the client continued to perform reimbursement tasks. In the actual drill, the RTO reached about 90 seconds.

Alibaba Cloud HBR and HDR

Typical Application Scenario for Hybrid Backup Recovery (HBR)

Data Protection in Various IT Environments

  1. Features easy-to-use, out-of-the-box services, and rapid deployment within minutes, reducing learning costs.
  2. Uses encryption and multiple copies to ensure secure and reliable cloud backup. The data reliability is 99.999999999%.
  3. Uses deduplication and compression to reduce bandwidth occupation and backup costs, and backs up data on the cloud with very limited bandwidth.
  4. Supports elastic scaling and the Pay-As-You-Go mode, and provides multiple discount packages to meet the requirements of prepaid customers.

Centralized Backup of Multiple Branches + Cross-Region Disaster Recovery

  1. Backup storage hardware devices do not need to be deployed or managed in each IDC, reducing the management complexity and O&M costs.
  2. Backup data can be managed in a uniform manner.
  3. Data sources with variable lengths can be efficiently deduplicated, with a deduplication ratio of up to 30:1. This reduces the network bandwidth and storage resource consumption, and shortens the backup window.
  4. The client data is permanently and incrementally backed up on the cloud. The HBR repository is fully replicated at each time point. This improves the backup and recovery efficiency, and achieves quick recovery.

Typical Application Scenario for Hybrid Disaster Recovery (HDR)

Real-Time Replication of the Core Business on the Cloud + Cloud Disaster Recovery Takeover

  1. Meets the customer’s requirements for core business data protection and enables remote disaster recovery with public cloud platform capabilities.
  2. Ensures continuous data protection, application consistency, and second-level RPO.
  3. Supports elastic scaling and on-demand configuration. During normal times, ECS instances do not need to be created on the cloud, thereby reducing the cost by at least 20% compared to traditional real-time replication solutions at the OS layer.
  4. Provides an orchestrated one-click disaster recovery mode that enables the customer to pre-deploy the key steps of the disaster recovery takeover, achieving minute-level RTO.

Local Backup + On-Demand Disaster Recovery Configuration on the Cloud

  1. Meets the customer’s local backup requirements, and supports on-demand remote disaster recovery. Uses public cloud platform capabilities to allow the customer to recover business quickly if disasters occur, without the need to build disaster recovery IDCs, thereby reducing disaster recovery costs by 70%.
  2. Supports elastic scaling and on-demand configuration. During normal times, ECS instances on the cloud do not need to be restored or started. The customer uses only the disaster recovery repository resources on the cloud. Such resources support elastic scaling.
  3. Enables the off-cloud IDC to regularly back up data, ensuring hour-level data backup RPO and on-cloud or off-cloud system data recovery RTO.
  4. Features high reliability. Based on the Alibaba Cloud infrastructure, HDR ensures reliable, secure, and timely data recovery when disasters occur.

Local Backup + On-Demand Disaster Recovery Configuration on the Cloud

  1. Makes full use of public cloud resources to build a big data cluster on the cloud.
  2. Uses asynchronous real-time replication technology, enabling the RPO to be close to zero and smooth scaling to the cloud.
  3. Uses two active clusters on and off the cloud to run different types of business. No resources are idle and the total cost of operation (TCO) is low.
  4. Expands nodes elastically on the cloud to provide fast and stable computing resources to meet fluctuating traffic demands.
