Relying exclusively on cloud storage for data backups can lead to permanent data loss. While the cloud is a convenient tool, it shouldn’t be your only backup solution. I’ll share some real-life examples of what can happen and offer advice on a safer approach.
Data is valuable, whether it’s personal memories like home videos and pictures, or professional assets that have a financial impact, such as business documents. For some, like me, the loss of YouTube video backups isn’t a huge deal. But for others, the loss of important personal or financial data is catastrophic.
Google Drive
In 2023, Google Drive users reported files randomly vanishing. The files weren’t in the trash—they were gone from the platform entirely, with months of data lost. Google eventually offered a partial fix for users of the Google Drive desktop app, allowing them to force a sync to recover some files. However, this fix was useless for people who only used the web browser, and their data was permanently unrecoverable.
Google Cloud Enterprise
Another major incident in 2024 involved Unisuper, an Australian company, losing data worth hundreds of millions of dollars. Google Cloud’s own website acknowledged that the incident was caused by a configuration error made by their technicians. They left a parameter blank during a deployment, which unintentionally triggered an automatic data deletion. Google stated they’ve since corrected this to prevent it from happening again.
In the Unisuper incident, Google’s internal report downplayed the extent of the damage and their role in the recovery. Google deleted the entire Google Cloud account, including backups in multiple geographic regions. Google’s statement suggested they assisted 24/7, but they couldn’t recover the data because they had permanently terminated the account and all associated services. Unisuper was able to recover its data only because it had backups with a different, third-party provider. This highlights the importance of not relying solely on a single cloud provider.
Microsoft OneDrive
This lesson is reinforced by a separate, personal case involving OneDrive. A user lost 30 years of irreplaceable photos and work after their account was locked and eventually deleted by Microsoft. Despite filing numerous forms with Microsoft support, they received only automated responses and no human assistance. Speculation suggests the user may have uploaded copyrighted material, which triggered an automated deletion, though this is not confirmed. This situation again underscores the danger of having all your data eggs in one basket, as the user had no alternative backup.
Amazon AWS
Another user recently lost ten years of data after their AWS account was deleted without warning. While these incidents aren’t widespread, similar reports of random AWS account deletions and data loss have been found on forums like Reddit.
The affected user argued that they didn’t put all their eggs in one basket, citing that they followed AWS best practices with multi-region replication, disaster recovery switches, and proper backup architecture. However, this is still considered single-provider risk. When you pay for a subscription service, you are renting the space, not owning it. You’re completely reliant on the provider upholding their end of the agreement. The user learned a difficult lesson: having backups spread across a single provider, even with high-end redundancy, isn’t enough. It’s like storing all your valuables in one bank vault, only for the entire bank to get shut down by a tornado or robbed.
During the 20-day period the user was trying to recover their data, an AWS insider allegedly reached out. This person claimed that the data was unrecoverable and that AWS staff were unsure how to fix the issue, which is why the process was delayed. The insider suggested the problem was not isolated, affecting multiple accounts that were low-activity or part of a proof-of-concept. The data was ultimately gone, and AWS confirmed the account and its contents were permanently deleted.
What You Can Do
This situation, along with the previous examples from Google Drive and OneDrive, illustrates a crucial point: no matter how robust a cloud provider’s internal systems are, a single service termination can wipe out all your data, regardless of location or backup architecture. The only true safeguard is to maintain backups with a separate provider or on a local physical medium.
So what’s the solution? You have a few options to avoid a similar fate:
- Multiple Cloud Providers: Distribute your data across different cloud services like Google Drive and Microsoft OneDrive. If one account is locked or deleted, your data should still be safe on the other.
- Hybrid Model: Combine cloud storage with physical backups. Store one copy of your data on a cloud service and another on physical hard drives in your home or office. This provides a safety net if your cloud provider fails.
- Local-Only Backups: This is my preferred method. Keep all your backups on local, physical drives. I use multiple hard drives in my computer and external hard drive bays. I also have an off-site backup at my in-law’s house, which I update monthly. This protects my data from a potential disaster like a fire or flood at my home.
Building on the idea of local backups, I might eventually take another step: storing a copy of my data in a bank safety deposit box. This strategy addresses the risk of a regional disaster, like a tornado, that could affect both my home and my in-laws’ home, which are geographically close. A small, high-capacity hard drive fits easily into a safety deposit box and provides an excellent layer of off-site protection.
There’s an important trade-off between different backup methods. Cloud services have a lower initial cost but can become more expensive over time with subscription fees. On the other hand, a physical backup strategy using external drives has a higher upfront cost but is more economical in the long run.
Another issue with cloud services such as Google Drive and Microsoft’s OneDrive, is that the data is constantly scanned by their AI and can’t be turned off. For many, this is a compelling reason to stick with a purely local or hybrid approach, prioritizing data privacy and control over the convenience of the cloud.
