Azure Backup manages backup (protection policy, backup, and restore) of Azure virtual machines (VMs). There are two types of Azure backup models, the Recovery Services vault and Azure Backup service that you can utilize according to your SAP data backup needs.
- Recovery Services vaults support Azure VM backups, providing data resilience and meeting compliance requirements. You can implement this by creating a Recovery Services vault, enabling backup for the VM, and setting the backup frequency and retention schedule.
- The Azure Backup service is a simplistic alternative that supports incremental backups, which are faster and require less storage. It uses the MARS agent for Azure Virtual Machine backup.
2. Securing Network Traffic
Azure provides different options for securing network traffic for SAP workloads to reduce the risk of unauthorized data access or loss. Azure DDoS Protection leverages always-on traffic monitoring and anomaly detection to mitigate DDoS threats.
- Azure’s built-in Network Security Group (NSG) and Azure Firewall services are excellent tools for controlling inbound and outbound traffic, providing additional security layers.
- Furthermore, Azure VPN Gateway connections use IPsec/IKE S2S VPN tunnels, and Azure ExpressRoute circuits use 802.1Q VLANs for secure traffic between Azure and your on-premises location.
3. Managing Azure Role-Based Access Control (RBAC)
You can manage access to your Azure resources using Azure RBAC. It provides a fine-grained access management of Azure resources, allowing to implement need-based access to improve data protection.
In RBAC model, permissions are granted based on roles, associated with specific actions that the user(s) can or cannot perform.
For example, a ‘Reader’ role permits viewing existing resources; ‘Contributor’ can create and manage all types of Azure resources but can’t grant access to others; the combination of ‘Owner’ enables full access to the resources, including an ability to delegate permissions.
4. Encryption for Data Protection
Azure offers multiple encryption options for data: Storage Service Encryption (SSE) for data at rest, always encrypted for data in transit, and Azure Disk Encryption for VM disks.
- Azure Storage Service Encryption (SSE) for Data at Rest, lets you encrypt data before it’s stored and decrypts it for you when you retrieve it.
- The ‘Always Encrypted’ feature in Azure SQL Database, similarly allows clients to encrypt sensitive data inside client applications and never reveal the encryption keys to the Database engine.
- Azure Disk Encryption uses the BitLocker feature of Windows to provide volume encryption for the OS and the data disks. The disk encryption keys and secrets are stored in the Azure Key Vault.
In conclusion, Azure incorporates powerful data protection services that ensure the safety and secure management of SAP workloads. Leveraging these resources will help you enhance data protection and ensure regulatory compliance while gaining peace of mind.
