How does the CVM Back up Data?
- When your CVM is a Cloud Block Storage host, you can back up your business data by creating a custom image of the system disk and a snapshot of the data disk.
- If you need to create a custom image, see Creating a Custom Image.
- If you need to create a snapshot, see Creating a Snapshot.
- When your CVM is a local disk host, your system disk can be backed up by creating a custom image. However, you still need to customize the backup policy for the business data in your data disk.
Usually, you can use FTP to back up the data in the server to other places. For specific FTP deployment methods, you can see:
- Windows operating system: Windows Instance of Setting up FTP service.
- Linux operating system: Linux Instance of Setting up FTP service.
- In addition, if you have higher requirements for data security, you can also pay for more professional third-party customized backup services.
Is There Any Common Data Backup and Recovery Solution?
Depending on different use cases and business situations, the applicable data backup and recovery solutions are also different. Here are some general suggestions we provide, use them according to your actual situation:
- Use Cloud Block Storage Snapshot Function to back up instances regularly.
- Deploy key components of applications across multiple availability zones and replicate data appropriately.
- Use Elastic IP to perform domain name mapping to ensure that the service IP can be quickly redirected to another CVM instance when the server is unavailable.
- Check monitoring data and set up appropriate alarms regularly. See Cloud Monitoring for more information.
- Use auto scaling to handle bursty requests. See Auto Scaling for more information.
