As Australian organisations move critical workloads to the cloud, Microsoft 365 has become central to their digital operations.
However, a dangerous gap is widening between perceived security and actual data resilience.
According to Syncro’s 2025 MSP industry survey, 60% of MSPs report that Microsoft 365 supports over 80% of their client base. Yet, despite this total reliance, nearly 30% of MSPs have experienced preventable data loss – incidents that could have been avoided with a dedicated, third-party backup strategy.
The Availability Myth
The primary friction point for the modern MSP remains a misunderstanding of the SaaS Shared Responsibility Model. Many clients, and a surprising number of service providers, operate under the “Availability Myth”: the belief that because the service is “up,” the data is “safe.”
In reality, Microsoft ensures the infrastructure availability; the partner and the client remain solely responsible for the protection and recovery of the data living within that infrastructure. As Grant Crough, Founder and CISO at LEAP Strategy, puts it: “Microsoft runs the service, but partners and customers still own data protection and recovery.”

4 Pillars of a Resilient 365 Strategy
For Australian MSPs managing multi-tenant environments, “basic” protection is no longer a viable service level. To mitigate risk and deliver high-value outcomes, the following pillars are non-negotiable:
- Comprehensive Collaboration Coverage: Microsoft Teams is the modern boardroom, yet 1:1 chats are frequently excluded from standard backup sweeps. In the event of an audit, legal investigation, or internal dispute, these missing logs represent a significant compliance liability.\
- Hardened Cyber Resilience: Modern threat actors don’t just target production data; they go for the lifeboats. To ensure a clean recovery path, backups must incorporate immutability and air-gapping. If the backup can be altered or deleted by the same credentials used in the production environment, it isn’t a backup – it’s a vulnerability.
- Operational Consolidation: Managing a fragmented stack of “point solutions” for different tenants increases troubleshooting overhead and slows down incident response. Efficiency in 2026 is driven by single-pane-of-glass management that scales without adding headcount.
- Data Sovereignty and Compliance: With the Australian regulatory landscape tightening, knowing exactly where your client’s data sleeps is paramount. Local storage options are no longer a “nice to have” for clients under GDPR or HIPAA-aligned frameworks; they are a prerequisite for trust.
The DRN Take
Having made a career as a SME on backup and business continuity, backup has never been a “set-and-forget” background task.
In a landscape where 30% of your peers are already losing data, the distinction between a “provider” and a “partner” is defined by the ability to restore quickly, cleanly, and predictably. When the inevitable incident occurs, “the service was up” will be a cold comfort to a client with a wiped directory. It’s time for MSPs to close the gap.
