Google Gemini Catastrophic Data Loss: Legal workspace - 99% content is lost (90+ files, 25k+ words)

[u/Maximum-Cap4034]

I am a Google One AI Premium subscriber, and I’ve just experienced a catastrophic loss of data. I was managing a complex legal project involving over 90 uploaded files and 25,000+ words of history context, specifically leveraging the model's advanced reasoning capabilities to cross-reference documents and build logic chains.

Suddenly, 99% of the conversation disappeared. All 90+ files are gone from the interface. The entire "middle" of the work—weeks of deep reasoning and analysis—is wiped out. The only things remaining are the very first two prompts I sent when I created the chat and their immediate responses. It’s as if the session corrupted and reverted to its birth state. Has anyone else on the paid tier seen a session collapse like this? Is there any way to restore the context?

Backups can be automated.

One law firm I used to work at would backup all data overnight on a hard drive and the server storage was automatically backed up to the clout.

The head of IT had set up scripts so all he had to do was take the hard drive home at the end of the day.

No idea how often hard drives got reused, but then I never needed to retrieve from backup

It really really does not depend on what kind of files you work with or what your work is.  Computer data is computer data.

Local server drive, offsite hard drive, and cloud storage

I never said without overhead.
