SaaS Shared Responsibility: Why You Must Back Up Your Own Data

SaaS Shared Responsibility: Why You Must Back Up Your Own Data

Vijay Raina is a distinguished authority in the world of enterprise SaaS technology and software architecture, bringing years of experience in designing resilient cloud systems. As organizations have shifted their entire operational backbone to platforms like Microsoft 365 and Salesforce, Vijay has been at the forefront of advocating for a deeper understanding of the “shared responsibility model,” a concept that is often cited but rarely fully implemented. His insights bridge the gap between high-level software design and the gritty reality of cybersecurity, particularly as the industry grapples with sophisticated social engineering and large-scale data exfiltration. In this discussion, we explore the critical distinction between platform uptime and data recoverability, the evolving landscape of global compliance, and the strategic necessity of independent backups in an era where data is the most targeted corporate asset.

Many organizations operate under the comfortable assumption that platform availability and data protection are effectively the same thing, yet data loss remains a persistent threat. How do you define the line where a vendor’s responsibility ends and a customer’s begins?

The most dangerous myth in modern cloud computing is the belief that because a service is “up,” your data is “safe.” Microsoft and Salesforce are titans of reliability, and they make it incredibly clear in their legal terms that while they own the infrastructure and platform availability, the customer is the sole owner of the data and its protection. We see a staggering disconnect here; for instance, a 2024 Gatepoint Research survey highlighted that 58% of executives mistakenly believe Microsoft is responsible for backing up their SaaS data. This misunderstanding leads to a false sense of security that shatters the moment a malicious deletion occurs, which was cited as the most common cause of data loss by 87% of IT professionals in a recent global survey. In my architectural reviews, I always emphasize that “shared responsibility” means the vendor secures the “where,” but you must secure the “what”—which includes managing your own backups, recovery testing, and long-term retention policies.

The 2025 ShinyHunters cyberattack was a watershed moment for the industry, specifically targeting Salesforce customers through social engineering. What does an incident of this magnitude tell us about the limitations of native platform security?

The ShinyHunters incident was a chilling wake-up call because it bypassed technical firewalls through the oldest trick in the book: social engineering over simple phone calls. By tricking employees at major firms like Adidas and Allianz Life into authorizing data extraction, the attackers managed to compromise an alleged 1 billion records across more than 30 organizations. This highlights a critical vulnerability: even the most secure platform in the world cannot stop a “legal” data export authorized by a compromised user. For the companies involved, the lack of independent, off-site backups turned a security breach into an existential crisis, forcing them to choose between paying a heavy ransom or accepting permanent data loss. It proved that native safeguards are often insufficient against insider threats or sophisticated social engineering, making a geographically separate and immutable backup not just a best practice, but a survival requirement.

Beyond the immediate threat of cyberattacks, how do the varying retention windows offered by SaaS providers create a “compliance gap” for enterprises governed by strict regulations like HIPAA or SOX?

There is a massive, often ignored delta between what a SaaS vendor provides for operational recovery and what the law requires for governance. If you look at Microsoft 365, for example, the default retention for deleted Exchange Online items is just 14 days, which you can stretch to 30, while SharePoint and OneDrive hold onto the recycle bin for only 93 days. Now, compare that to the reality of a SOX audit, which requires a seven-year retention for financial archives, or HIPAA’s mandate for a six-year hold on security documentation. When an auditor asks for a record from three years ago and all you have is a 93-day recycle bin, you are facing severe regulatory exposure. Organizations must realize that native tools are designed for quick “undo” actions, not for the long-term, purpose-limited processing and erasure mandates of GDPR or the rigorous archival demands of financial and healthcare laws.

Given that native SaaS tools often have short recovery windows and limited granular restore capabilities, what specific technical features should enterprises look for when building a more resilient backup stack?

An enterprise-grade backup strategy must move beyond the basic “point-in-time” restoration offered by standard vendor services. While it was a significant move for Salesforce to acquire Own for $1.9 billion to bolster their “Backup & Recover” offering, many organizations still need third-party tools that provide daily, granular backups and the ability to flag unusual data activity before it becomes a catastrophe. You need to look for solutions that offer “immutable” backups—data that cannot be changed or deleted even if the primary admin account is compromised—and ensure these backups are stored in a different cloud environment or geographic region. Furthermore, the ability to perform verified recovery procedures is paramount; a backup is only as good as your ability to restore it under pressure without bringing the entire business to a halt. We are seeing a shift where boards are now treating SaaS backup as a critical requirement, with projections suggesting that by 2028, 75% of enterprises will prioritize this, a massive jump from the 15% we saw in 2024.

What is your forecast for the future of SaaS data governance as organizations move toward more decentralized and multi-cloud environments?

The next few years will see a total professionalization of SaaS data governance, moving it out of the IT basement and directly into the executive boardroom. As cloud environments become more fragmented, the risk of “strategic governance gaps” grows, where leadership wrongly assumes the cloud is a “set it and forget it” solution. I anticipate that cyber insurance providers will become the primary drivers of change, as they increasingly refuse to cover organizations that cannot demonstrate immutable, tested backups as a prerequisite for a policy. We will see a more holistic approach to data ownership where executive ownership is the norm, and cross-functional teams—comprising legal, IT, and security—will meet regularly to map their technology stacks against shifting global regulations. Ultimately, the organizations that survive and thrive will be those that treat their SaaS data with the same rigor and paranoia as they once treated their on-premises servers, recognizing that in a digital economy, data resilience is the only true competitive advantage.
