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.

Data: The Core of Digital Operations

In the digital economy era, data is growing exponentially. In just a few years, the amount of data has jumped from the TB level to the PB or even ZB level.

Case Study: Data Center Accidents

In August 2018, an international cloud service provider reported data leakage because its sales staff did not follow the specifications for a bucket.

Alibaba Cloud HBR and HDR

Hybrid Backup Recovery (HBR) is an easy-to-use and cost-effective online backup service. This service helps customers back up data from desktops, servers, or VMs to a backup repository on Alibaba Cloud, which ensures secure and efficient cloud storage, backup, and management of customer data.

Typical Application Scenario for Hybrid Backup Recovery (HBR)

Data Protection in Various IT Environments

A customer requires data protection in different IT environments, including physical machines and virtual platforms in a local Internet data center (IDC), ECS servers on Alibaba Cloud, and servers on other public cloud platforms.

  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

A customer needs to replicate the production environment in real time to ensure that the business can be quickly taken over on the cloud if a business failure occurs in the local IDC.

  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

A customer needs to replicate the production environment locally to ensure quick recovery of data in the local IDC if the data is deleted by mistake or a disk failure occurs.

  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

A customer has deployed a Hadoop big data cluster, which contains hundreds of TB of data, in the local IDC. If a remote disaster recovery cluster of the same size is built, a lot of resources are idle and the costs are high.

  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.

Combining Alibaba Cloud Hybrid Backup Recovery with Hybrid Disaster Recovery

Grading RPO and RTO

HBR and HDR support multi-level RPO and RTO to meet different business disaster recovery requirements.

Quick and Easy-to-Use

No hardware or gateway device is required.

Cost-Effective and Purchase on Demand

The deduplication ratio of up to 30:1 allows 30 copies to occupy the original space of only one copy.

Safe and Reliable, and Multi-Region Disaster Recovery

The data is backed up in multiple versions. A full copy is stored at each time point.

Whole-System Disaster Recovery; No Business Transformation Required

The whole system is backed up and recovered. Customers can recover the same business system on the cloud without the need to change applications or IP addresses.
