Google Drive sync has no undo

When I first built Agent M, some research led me to host my Agent Memory Vault in a Google-Drive-synced folder. It was a simple and effective way to make the vault accessible across devices — and, with some work, even reachable from Claude and Gemini on the web. Over time, though, this decision has come back to bite me a few times. Drive has no version history, just a trash bin. I recently had an overwrite I couldn’t walk back, and the odd sync-conflict file left behind after two machines wrote at once. And because I also use Obsidian to work in the vault, I had to do some gymnastics to keep Drive from syncing its index. So today I learned that “it syncs” is not “it’s backed up” — and I made plans to move the memory under git, to finally get history, diffs, and an undo.
