AnalyticDB for MySQL protects your data against two distinct threats: unauthorized access to stored data, and accidental data loss. The following features address each threat.
| Feature | Protects against | Details |
|---|---|---|
| Disk encryption | Data leaks — encrypted data remains unreadable even if data leaks occur | Disk encryption |
| Data backup and restoration | Accidental data loss from unintended changes or cluster-level failures | Manage backups, Clone a cluster |
Disk encryption
Disk encryption guards against data leaks at the storage layer. When enabled on a cluster, AnalyticDB for MySQL encrypts every data disk using Elastic Block Storage (EBS) — so even if data leaks occur, the data cannot be decrypted.
For configuration steps and key management details, see Disk encryption.
Data backup and restoration
Data backup and restoration protects against data loss from accidental changes. The feature is enabled automatically when you create a cluster — no manual setup is required.
To manage backup schedules and retention, or to restore a cluster from a backup, see Manage backups and Clone a cluster.
