What happens to the data when a cloud server is destroyed?

When a cloud server is destroyed, the data stored on it is typically not lost permanently due to the design of cloud infrastructure. Cloud providers implement redundancy and backup mechanisms to ensure data durability and availability.

  1. Data Redundancy: Cloud servers usually store data across multiple physical disks or nodes within a data center. If one server fails, the data remains accessible from other replicas.
  2. Backups: Regular backups are created and stored in separate geographic locations. Even if the entire server is destroyed, backups can be used to restore the data.
  3. Disaster Recovery: Cloud platforms offer disaster recovery solutions, such as automated failover to secondary regions, ensuring minimal downtime and data loss.

Example: If a virtual machine (VM) on a cloud server is deleted due to hardware failure, the data stored on its attached volumes can often be recovered from snapshots or backups.

For such scenarios, Tencent Cloud provides services like Cloud Block Storage (CBS) with snapshot capabilities and Cloud Backup (CBR) to automate data protection. Additionally, Tencent Cloud’s Multi-AZ deployments ensure high availability and data resilience.
