Most backup solutions today are distributed, focusing on data from various business units. Structured data often uses backup appliances, big data and unstructured data use distributed storage, and massive data archiving relies on tape libraries. However, the trend is moving towards centralized integration.
Centralized Backup and Disaster Recovery
Should application and data disaster recovery, backup, and archiving be centralized? This involves creating a unified “backup warehouse” that handles both application and data backups and provides CDM-like functionality for backup copies.
Goals of Backup
The primary goal of backup is recovery, which ensures business continuity and information security. The backup system can be independent but must always prioritize business data. Backup strategies should be based on the properties of business data.
Centralization in Management
Centralizing backup platform management, backup media management, and backup architecture can improve efficiency. Previously, backup and disaster recovery systems were standalone. Now, with stricter business continuity and regulatory requirements, they must be considered in initial project planning.
Case Study: Company Example
In our company, the backup system is integrated into a group-level information security platform, managed centrally. Any branch needing backups must register and follow policies set by the headquarters. Remote data storage with centralized management ensures data security, forming a backup pool. This approach aligns with the Data Security Law, making the backup system a crucial part of data security.
Importance of Backup
Backup is essential for business continuity and is increasingly integrated into daily operations and security frameworks due to strict regulations.
Unified Planning
Classification and Grading: Classify and grade business systems and data based on importance to determine appropriate backup and disaster recovery strategies.
Multiple Solutions: Use a combination of backup and disaster recovery solutions to address different scenarios, costs, and technical limitations.
Implementation Considerations
Whether to use a single management system or integrate the solution into a platform depends on the organization’s IT infrastructure. The backup system should be independent of the disaster recovery system, serving as the last line of defense. It should be stored independently to ensure data can be fully restored in extreme situations, maintaining business continuity.
