In the era of digital economy, data is growing exponentially. In just a few years, the amount of data has jumped from terabytes to PBs and even ZBs. The total amount of global data is predicted to reach 19.4 ZB by 2018. The global data growth rate will be more than 25% per year in the next few years, and the global data is expected to hit 50 ZB by 2020.
Undeniably, data is the core of digital operations, and data security determines the survival of enterprises. If a data center fails, enterprises may face irreversible damages. In August 2018, an international cloud service provider reported data leakage because its sales staff did not follow the specifications on a bucket. In July 2018, a Chinese cloud platform was exposed to a serious failure, which directly led to the loss of data of a startup company. Because of this incident, the startup had to rebuild the company from scratch.
In January 2017, the O&M personnel of a code hosting platform mistook the production environment as a test environment in multi-terminal switching and deleted the database of the production environment. In November 2014, a financial payment company experienced a system failure, causing nearly 400 million duplicates to be reported.
These are only a few examples that illustrate the importance of data security for enterprises. According to statistics by IDC, 55% of companies that experienced disasters in the past decade collapsed. For the remaining 45%, 29% went bankrupt within two years due to data loss. Only 16% survived.
According to a Gartner report, two-fifths of the companies that experienced system downtime due to major disasters never resumed operations, and one-third of the remaining companies went bankrupt within two years.
In this context, enterprises are in urgent need to strengthen data protection.
A hybrid cloud disaster recovery solution is the first choice for enterprises' digital transformation. In the past, a traditional backup and disaster recovery solution is an architecture system similar to the production center, built in a disaster recovery center. Although this solution meets the data backup and replication needs of the production center, it poses many challenges to enterprises due to its long implementation period, inconvenient implementation, expensive equipment, and complicated O&M.
Compared with the traditional backup and disaster recovery solution, the hybrid cloud backup and disaster recovery solution features high efficiency, high availability, high cost performance, and free O&M. This modern solution helps customers securely and efficiently back up files, databases, virtual machines, and even the whole system locally or on the cloud. In addition, the application server system backed up on the cloud can work as a virtual server, which delivers the required RPO and RTO to ensure stable services and disaster recovery on the cloud.
The hybrid cloud backup and disaster recovery solution has the following advantages:
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, and virtual machines to a backup repository on Alibaba Cloud, which ensures secure and efficient cloud storage, backup, and management for customer data.
Different from the HBR service, hybrid disaster recovery (HDR) provides cloud + local dual backup and cloud disaster recovery for enterprise applications. The HDR service protects servers, files, and applications based on the hardware and software of the backup and disaster recovery server to ensure service continuity. In addition, the HDR service can be used for disaster recovery drills and data analysis.
In response to data protection in the big data cluster architecture, Alibaba Cloud released the first big-data backup and disaster recovery solution on the public cloud.
Customers need to back up the production environment locally to ensure quick recovery of local data if the local IDC data is mistakenly deleted or a disk failure occurs.
The local backup data is remotely disaster-tolerant. In case of disasters in the local IDC, services can be quickly restored in the disaster recovery center so that services are continuous or the interruption time is short.
The service system consists of database servers, file servers, application servers, and other servers.
The HBR service has the following advantages:
A Hadoop big data cluster in the local data center contains hundreds of terabytes of data. Self-building a remote disaster-tolerant cluster of the same size will cause a lot of idle resources and high costs. If the required RPO is close to 0, this cannot be satisfied by the traditional DistCp solution.
The HBR service has the following advantages:
In summary, Alibaba Cloud Hybrid Backup and Disaster Recovery solution has the following advantages:
The amount of data is calculated and charged based on the cloud storage space instead of the source backup amount, minimizing backup costs. The infrastructure of the public cloud platform reduces more than 70% costs compared with the traditional disaster recovery center.
Currently, Alibaba Cloud is the first to provide customers with the most complete hybrid cloud backup and disaster recovery solution, including the local data center, private cloud, cross-public cloud, and other hybrid cloud scenarios. Alibaba Cloud hybrid backup and disaster recovery solution is widely used in finance, manufacturing, education, hotels, retail, government, enterprises, and other industries. This solution provides not only data protection for enterprises' local data centers and multi-cloud environments, but also new channels for traditional enterprises to access the cloud and enjoy the convenience and benefits brought by cloud computing.
