Are You Overpaying for M365 Backup? Discover 2025’s Smartest Data Protection and Cost-Saving Strategies

Considerations When Using Native Microsoft 365 Backup

Following the 2024 release and general availability of Microsoft 365’s native backup solution, many IT professionals and managed service providers (MSPs) advise using additional backup options. Key reasons include:

• Concentration of Risk: Keeping backups solely within the Microsoft ecosystem can expose organizations to broader cloud risks, such as accidental deletions or outages. Reports have described situations where production and backup data were both affected by a single provider incident.
• Feature Set: Some granular restore functionalities (such as file-level recovery) in Microsoft’s backup may have limited availability as of 2025.
• Relative Cost: Microsoft’s native backup pricing may be significantly higher than certain established third-party alternatives.
• Data Resilience Guidelines: It is widely considered a best practice to maintain at least one backup copy outside of the primary cloud provider.

Overview of Third-Party Backup Solutions

Several third-party backup platforms, including Veeam, Rubrik, NetApp, Wasabi, and Pure Storage, are commonly used for M365 and enterprise data backup in 2025. These solutions typically offer:

• Granular Restore Capabilities: Options for restoring individual emails or undertaking full system recovery.
• Deployment Flexibility: Operational models that support public cloud, on-premises, or colocation environments such as Equinix.
• Ransomware Mitigation & Data Security: Features like immutable storage, data versioning, and enhanced access controls.
• Compliance Tools: Support for various regulatory requirements regarding data retention, monitoring, and sovereignty.

Factors Affecting Backup Costs

Key Elements Beyond Storage

When evaluating cloud backup solutions in 2025, organizations are encouraged to consider cost aspects beyond just storage capacity:

• Network Egress Fees: Charges may be applied when data exits a cloud vendor’s environment.
• Retrieval Costs: Accessing backups, particularly from archival storage tiers, may result in additional expenses.
• Bandwidth and Transfer Charges: Charges related to moving data between clouds or across regions.
• Service Level Agreement (SLA) Tiers: Higher service guarantees for backup and recovery can influence overall costs.

Improving Cost Efficiency

An effective backup strategy integrates:

• Hybrid Cloud Deployment: Utilizing both public cloud and dedicated or colocation resources (e.g., at Equinix) to align backup and recovery needs with cost.
• Optimized Storage Classes: Assigning data to appropriate storage tiers—using lower-cost options for archives and high-performance options for critical data.
• Colocation Benefits: Using colocation facilities equipped with private cloud connections can help reduce or avoid public cloud egress fees, improve recovery speeds, and assist with compliance needs.

Data Security Practices for 2025

Best practices for enterprise data protection include:

• Vendor and Cloud Diversity: Leveraging multiple providers and platforms helps to distribute risk.
• Routine Backup Testing: Regularly restoring data in test environments helps verify recoverability and cost-effectiveness.
• External and Immutable Copies: Maintaining isolated or off-cloud backup sets, with immutable storage options where possible.
• Integrated Security Measures: Pairing backup solutions with endpoint protection and staff security training (for example, options from Palo Alto and KnowBe4).

The Role of Equinix in Hybrid and Cloud Strategies

Equinix provides resources for enterprises pursuing hybrid cloud, colocation, and data protection strategies in 2025:

• Managed Storage Offerings: Access to storage appliances and as-a-service arrays without upfront hardware purchase.
• Direct Cloud Connect: Private connections to major cloud platforms, supporting cost management and flexibility.
• Enhanced Security Controls: Advanced security and monitoring features designed to help meet compliance standards.
• Resilience Features: Service level agreements and a global infrastructure to support business continuity objectives.

Key Steps in Developing a Cloud Backup Plan

1. Define Objectives: Clarify recovery time, data sovereignty, and compliance requirements.
2. Choose Providers: Evaluate third-party backup software, hardware, and cloud services appropriate to organizational needs.
3. Architect Storage: Combine cloud and colocation resources to optimize for resilience and cost.
4. Budget for Total Cost: Include all network, retrieval, and support costs, and consider reserved capacity plans where relevant.
5. Schedule Testing: Plan routine backup recovery tests to maintain compliance and readiness.
6. Embed Security Culture: Incorporate strong security controls and foster employee awareness for effective backup management.

Cost Management Recommendations

• Weighing Short-Term and Long-Term Expenses: Initial low storage costs in the public cloud may be offset over time by additional fees as data volume grows.
• Matched Storage Allocation: Use less expensive storage for archival data and higher-performance tiers for data needed more frequently or urgently.
• Minimizing Egress Fees: Where feasible, colocation with dedicated cloud connectivity can reduce costs associated with transferring data out of public clouds.

Practical Guidance for 2025

• Diversify backup strategies—avoid single-cloud reliance.
• Consider established third-party vendors for enhanced data protection.
• Explore hybrid strategies, including colocation for critical backups.
• Analyze the comprehensive costs of your backup architecture.
• Regularly test recovery procedures for effectiveness.
• Integrate data security, compliance, and cost management into your overall cloud strategy.
