As an experienced CMS operation personnel in the information security field, I am well aware that data is the lifeline of a website, especially when managing multiple sites, the strategy of data backup and recovery is of paramount importance.AnQiCMS was designed with the needs of enterprise-level applications in mind, providing system data backup and recovery features to ensure the safety of users' data assets.For a multi-site environment, we need a clear and efficient strategy to ensure the independence of each site and the integrity of the overall data.

Understanding the data structure of AnQiCMS

Before delving into specific methods of backup and recovery, it is first necessary to clarify the data structure in the AnQiCMS multi-site environment.Based on the architectural characteristics of AnQiCMS, each independent site usually has its dedicated data storage, which is mainly divided into two core parts: database and file system.

AutoCMS supports multi-site management, allowing each new site to be configured with an independent database name and site root directory.This means that the data for each of your sites is relatively isolated.The core application files, common resources, and independent databases and file directories of each site together constitute the complete AnQiCMS multi-site data.

The core strategy of multi-site data backup

In view of the characteristics of the AnQiCMS multi-site environment, a comprehensive data backup should cover the following key components:

Database backup

Each independent site created in AnQiCMS will have a dedicated database.This database carries all the structured data of the site, including content (articles, products, pages, etc.), categories, tags, users, configuration settings, and various functional module data.

To backup these data, you need to perform independent operations on the database of each site. Common database backup methods include exporting SQL files using database management tools (such as phpMyAdmin, Navicat), or through command-line tools (such asmysqldumpPerform the backup command. For example, for MySQL databases, you can execute commands similar to the following for each site's database:

mysqldump -u [用户名] -p[密码] [数据库名称] > [备份文件路径]/[数据库名称]_backup_$(date +%Y%m%d%H%M%S).sql

Make sure to perform this operation for each site and its corresponding database, and name the backup files properly so that they can be distinguished and located.

File system backup

The file system backup mainly includes two types of files: site-specific files and AnQiCMS core program files.

  • The root directory of the site (media resources and configuration)

    Each site is assigned a unique site root directory when created, for example/app/dev_anqicms.com.This directory stores all media files (such as images, videos, attachments) uploaded to this site, as well as site-specific template files, cache data, and so on.These resources are an indispensable part of the site content display.

    You need to regularly back up all files and folders under the root directory of each site. This can be done through a compression tool (such astar/zip) to package the entire directory, or usersyncUsing tools for incremental backup. It is recommended to separate media resources and configuration files, such as backing up the media folder separately, to ensure that recovery can be quickly located in case of a failure.

  • AnQiCMS Core Program File

    In addition to the independent data of each site, the core program files of AnQiCMS itself also need to be backed up. This includes the binary executable files and the mainconfig.jsonConfiguration file (especially including database connection information and port settings, etc., global configurations), as well as all shared template files across all sites (if any).These files are usually located in the root directory of the AnQiCMS installation.

    Although the data of each site is independent in multi-site mode, they share the same AnQiCMS program instance.Therefore, the backup of the core program can ensure quick redeployment at the system level when problems occur.

Backup Plan and Frequency

It is particularly important to formulate a reasonable backup plan for multi-site environments.The backup frequency should be determined based on the update frequency of your website content, the size of traffic, and the importance of data.For sites with frequent content updates, it is recommended to perform daily backups of the database and file system; for sites with less frequent updates, weekly or monthly backups may suffice.The automated backup script can significantly improve efficiency and reduce human error.

Steps for Data Recovery

Data recovery is the ultimate goal of backup work, and its purpose is to restore the website to normal operation status when data is lost or damaged.

Database Recovery

When you need to restore the data of a site, the first step is to restore its corresponding database. You can use database management tools to import the previously backed up SQL file, or through command-line tools (such asmysql）Execute the recovery command.

mysql -u [用户名] -p[密码] [数据库名称] < [备份文件路径]/[数据库名称]_backup_$(date +%Y%m%d%H%M%S).sql

Please make sure to confirm the name of the target database before performing the recovery operation to avoid overwriting incorrect data.

File system recovery

The file system recovery includes restoring the backed-up site root directory files and AnQiCMS core program files to the specified location.

  • Restoring the site root directory

    Extract or copy the backup of the media resources and configuration files of the corresponding site back to its original site root directory.If a file with the same name exists in the directory, it is usually chosen to overwrite.Ensure that the file permissions are set correctly after recovery, so that the web server can access it normally.

  • AnQiCMS Core Program File Recovery

    If the core program file is damaged, you need to restore the AnQiCMS core program backup (including binary files,config.jsonCopy it back to the main installation directory. After this, you may need to adjust according to the new environment.config.jsonSome parameters, such as port numbers, database connection strings, and others, and restart the AnQiCMS service.

Verify recovery

Data recovery completed, it is essential to conduct a comprehensive test of the restored site.This includes checking if the front-end pages, content, images, and links are displayed normally; logging into the back-end management interface to verify if all functions are available; and conducting random inspections of recently published content to ensure data integrity.Only after a complete verification can the success of data recovery be confirmed.

**Practical Tips and Considerations

To better ensure the data security of AnQiCMS multi-sites, the following are some suggested practices:**

  • Remote storage backupStore the backup files in a physical location or cloud storage service different from the AnQiCMS server to prevent complete data loss due to server hardware failure, natural disasters, and other causes.
  • Automated backup：Utilize scripts or third-party tools to implement automated timed backups of databases and file systems, reducing manual intervention and ensuring timely backups.
  • Regularly test the recovery processDo not wait until a real data disaster occurs before performing recovery tests.Regularly simulate data loss scenarios, execute recovery operations to verify the effectiveness of backup data and the smoothness of the recovery process.
  • Permission managementEnsure that the access permissions of backup files and directories are strictly controlled to prevent unauthorized access leading to data leakage or tampering.
  • Log recordingRecords all backup and recovery operation logs, including time, operator, backup content, etc., for auditing and fault troubleshooting.

Frequently Asked Questions

Q1: Do I need to back up the database separately for each site in a multi-site environment?

Q2: Besides the database and site root directory, do the core program files of AnQiCMS also need to be backed up?

Although the core program files of AnQiCMS usually do not contain website operation data, backing them up is still recommended as a **best practice. The core program files include AnQiCMS executable files, global configuration files (such asconfig.jsonEnglish.Backing up these files ensures that you can quickly restore the runtime environment when the program itself is damaged or needs to be migrated quickly, without the need to redownload and configure, especially when you have custom modifications or use a specific version.

Q3: AnQiCMS backend has a built-in graphical interface tool for one-click backup and restore?

According to the description of the advantages of the AnQiCMS project, it provides the core function of 'Resource storage and backup management'.This means that the background management system should have the corresponding configuration and operation entry.In actual operation, you usually find the relevant options in modules such as 'Function Management' or 'System Settings' in the background, where you can set up system data backup and recovery.The specific interface operation steps should be based on the actual display of the AnQiCMS version backend you are using.
