The rapid development of educational informatization promotes the continuous deepening of the application of technologies such as AI and big data in education, scientific research, and comprehensive management in colleges and universities, bringing new impetus to the innovative development of colleges and universities. However, the consequent risks of data security and business continuity should be considered.

I. Disaster Recovery Application Scenarios and Solutions

With the profound experience in data security and business continuity management within the education industry, Information2 has launched a series of application-scenario-based solutions, such as data migration, backup, CDP, application disaster recovery and file sharing network disk, aiming at the application data characteristics and disaster recovery needs of campus card, educational administration management system, library system, email system, portal website and file system.

1. Disaster Recovery for Educational Administration Scheduling Online Courses/Systems

Scenario Characteristics: Important data; continuous system operation; frequent concurrent access from multiple clients. 

Client  Requirements:Second–level RTO of key systems; terminal unaware when a failure occurs; no backup time window; small impact on system performance; data loss close to zero.

In the local and off-site environment, build the application high availability capability for the educational administration and smart classroom system based on i2Availability. Through its sophisticated monitoring platform, the system can monitor key indicators such as process status, network connectivity, CPU performance and server health in real time based on the heartbeat line judgment standard. Once any fault is detected, the backup server will start immediately and seamlessly take over the work of the main server to ensure the continuous and stable service. 

Based on i2CDP, provide comprehensive protection for the data of the educational administration and smart classroom system. Whether encountering logical errors, hard disk damage or virus attacks, i2CDP can ensure the security and integrity of the data. When needed, users can easily restore data at any point in time.

2. Campus System/Cloud Migration and Disaster Recovery

Scenario Characteristics: The competent department or the school coordinates the business system to move to the cloud; there are platform-type security risks in cloud data.

Client Requirements: The system realizes online hot migration without data loss; control the security of cloud data and back up the latest data locally.

In the seamless migration and data protection process from the local to the cloud, first, based on i2Move, the campus system is realized to be online hot migrated to the education cloud. Secondly, through i2CDP, the cloud data is backed up to the local machine room in real time. This strategy not only effectively prevents the risk of data loss caused by logical errors, cloud platform failures and virus attacks, but also ensures the bidirectional synchronization and protection of data between the cloud and the local.

3. Disaster Recovery for Database Data of Finance and Campus Card

Scenario Characteristics: High data security and sensitivity; large amount of data, high frequency of query and access.

Client Requirements: Data cannot be lost and can prevent ransomware virus attacks; has little impact on production performance and the data at both ends is consistent.

In the complex local cross-operating system environment, through the real-time replication and synchronization function of i2Active database semantic-level data, the real-time synchronization of the production-end Oracle RAC database to the target Oracle server is realized. This process not only ensures the real-time and consistency of the data, but also greatly improves the flexibility and maintainability of the system. At the same time, in order to further enhance the security of the data, a cascading method is adopted to synchronize the Oracle database data to the backup server in the off-site backup center in real time. The dual protection strategy can effectively prevent the risk of data loss and ensure the integrity and availability of the data.

4. Real-time Data Synchronization and Anti-virus Ransomware for Multi-tenants in Multiple Campuses

Scenario Characteristics: Multiple campuses and multiple machine rooms, frequent data access; scattered network data security risk points.

Client Requirements: Real-time synchronization of data in each campus, anti-virus ransomware; build an off-site disaster recovery center to prevent natural disasters such as fires and earthquakes; ensure the availability, integrity, continuity and recovery reliability of data.

Establish a production center in the main campus and a disaster recovery center in the core sub-campus (or cloud). Through the adoption of i2Cloud multi-tenant cloud disaster recovery management platform, convenient account management is enabled for key systems such as educational administration, student affairs, library, scientific research and campus card. With the help of i2COOPY, the data of the two places is synchronized in real time and ensures the high consistency and continuous availability of the data at both ends. Through i2CDP, the core data is continuously backed up. When the production center faces sudden dangerous events such as logical errors, virus attacks and fires, it can quickly recover through the backup data to ensure the continuity of the business and the integrity of the data.

5. School Multi-terminal File/Shared Cloud Disk Management

Scenario Characteristics: Massive types of data, chaotic management and low efficiency; frequent file copying, repeated transmission and scattered risk points.

Client Requirements: Secure access to files in different places and multiple terminals; collaborative intercommunication, backup and unified management of campus data; multi-level permission management of network disks and recovery of historical data; real-time, convenience and intelligent management of file updates and sharing.

Through i2Share, accounts are opened for teachers, students and school staff in need, enabling them to easily access files on the shared network disk at any time and any place through Linux, Windows, Mac desktop platforms and Android and iOS mobile platforms.

i2Share not only provides multi-terminal synchronization function, ensuring that users can seamlessly switch between different devices and obtain the required files at any time, but also has the full historical version recovery ability, effectively preventing data loss caused by misoperation or version changes. i2Share also performs well in terms of security, with file secure access mechanism, encrypted storage and other capabilities, providing users with more secure and flexible data storage and sharing options.
