How Backups Work

  • Backups are taken daily, and transaction logs are captured continuously.y
  • The retention period can be configured from 7 to 35 days.
  • Backups are stored in secure, redundant storage with AES-256 encryption

During a point-in-time restore, you can recreate a new server that reflects the database’s state at any specific time within the retention window.

Backup Storage Redundancy

You can choose from:

  • Locally redundant storage (LRS): Keeps data within a single data center
  • Geo-redundant storage (GRS): Replicates data across multiple regions for disaster recovery

For mission-critical workloads, GRS is highly recommended to ensure data durability even in the case of regional outages.

Read Replication and Geo-Redundancy

Data-in replication allows synchronization of data from a MySQL server hosted outside Azure to an Azure MySQL server. This is useful in hybrid cloud scenarios. Read replicas can also be deployed across Azure regions, which not only enhances performance but also serves as a real-time disaster recovery mechanism.

Azure ensures that these replication strategies are cost-effective and easy to deploy with minimal downtime.

Security Best Practices for Data Protection

Data protection isn’t just about backups—it also includes securing data in transit and at rest. Azure Database for MySQL includes several security capabilities:

  • Encryption: All data is encrypted at rest using Transparent Data Encryption (TDE) and in transit using SSL/TLS.
  • Firewall rules: Define allowed IP ranges to control access to the database server.
  • VNet integration: Use private endpoints to eliminate exposure to the public internet.
  • Role-based access control: Manage permissions using MySQL-native users and integration with Azure Active Directory.
