7 février 2015 Samedi SQL Sujet: Session 4 - Backup dans Azure, Bases de données hybrides (Éric Moreau) Cette session vous montrera comment prendre des backups de vos bases de données "on premises" vers Azure. Il vous montrera aussi comment utiliser des bases de données hybrides.

2. Cloud DR

3. Why Do We Need Cloud DR for SQL Server?
• An event can cause on-premises
SQL Server to become unavailable
‐ Temporarily (e.g. gateway failure)
‐ Permanently (e.g. flooding)
• A disaster recovery site is expensive
‐ Site rent + maintenance
‐ Hardware
‐ Ops

4. Typical Configuration
4

5. Characteristic of Cloud DR for SQL Server
• Deploy one or more secondary replicas for on-premises
SQL Server
‐ Replicas continuously synchronize
• At best region: West US, East US, East Asia, Southeast Asia,
North Europe, West Europe
‐ Political considerations
‐ Latency
• Low TCO
‐ VM and storage

Azure Storage, while keeping the compute
node of SQL Server on-premise
• Transparent Data Encryption (TDE) is supported
• No application changes required
• Centralized copy of data and log files
• Enjoy unlimited storage capacity in Azure
Storage (built in HA, SLA, geo-DR)
