roughly six months ago, Backblaze enacted a silent change that made its backup app stop uploading local data synced to “OneDrive, Google Drive, Dropbox, Box, iDrive, and others.”
How does it know? I assume the shittiest way, by just having a deny list of path prefixes.
Highly likely it is a list of folders to ignore. The alternative is much worse. If they are looking at user data to analyze patterns and type of data to decide folders to ignore.
I am a fan of backblaze, mostly their B2 storage, but this move is a bit disturbing.
I used to use Dropbox for cloud backup of important files, but I haven’t in years. However, I still have the Dropbox folder and I still have important files and receipts in there, more current than the last sync to Dropbox which was many many years ago.
This is quite concerning to say the least.
