I thought you said Dropbox overwrote a file, meaning that file was also being synced by Dropbox, and that Dropbox sync was working. So likely the older file version would also have been synced by Dropbox, which it then overwrote. Dropbox itself keeps old versions of files for 30 days. I think you're saying in this situation Dropbox wasn't syncing though?

My comment was pretty orthogonal to all the Backblaze stuff, which I realize now was confusing.

I think they’re saying that Dropbox didn’t have the original (old) copy of the file retained, even though the change was just 2 days ago, because the old version was ‘more than 30 days ago’. Which is bonkers.

I don't think that's how the 30 day timer works. Once a file is replaced by a new one, the old copy should persist for 30 days. So if it was overwrote 2 days ago, should have 28 days to recover it. But don't know about this situation

That it didn’t do that, despite that assumption, is what the op was complaining about.
