How to Estimate Costs for Azure Site Recovery

Azure Site Recovery Cost Elements

Understanding the costs behind Azure Site Recovery (ASR) is key for UK small and medium-sized businesses (SMBs) making disaster recovery decisions. Here's a breakdown of the main cost components that shape your ASR bill.

Licence Fees

ASR operates on Azure's pay-as-you-go model, with a base fee for each protected instance. These fees vary depending on whether you're using Windows or Linux and include:

• Automated protection and replication management
• Health monitoring and alerts
• Recovery plan orchestration
• Basic failover testing

Storage Costs

Storage charges cover two main areas:

• Cache storage: Used during the initial replication process.
• Target storage: Costs depend on the tier you choose - Hot, Cool, or Archive.

Selecting the right storage tier depends on your recovery time objectives (RTOs) and recovery point objectives (RPOs). This ensures you balance cost with performance.

Network Charges

Network-related costs include:

• Fees for outbound data transfers from Azure data centres
• Charges for cross-region replication within the UK
• Costs for dedicated connectivity options like ExpressRoute circuits or VPN gateways

Since network pricing depends on data volumes and connectivity choices, it's a good idea to check Azure's latest pricing to estimate your expenses.

Computing Costs

These costs are tied to:

• Test failovers, which are charged at standard virtual machine rates
• Actual failovers, which incur full computing costs in the secondary region
• Maintaining a minimal recovery environment

To manage these costs, consider scheduling test failovers during off-peak times, automating the shutdown of non-critical test environments, and checking for any available licensing benefits.

Regularly monitoring and adjusting resources based on usage patterns is essential to control ASR expenses. Azure Cost Management tools can help UK SMBs track spending and find ways to reduce costs.

1. Azure Site Recovery Pricing

Azure Site Recovery costs depend on the number of protected instances and how much you use resources like licensing, storage, network, and compute.
