Those top-6 never resulting in more than a few hours of data loss in one case. The Tencent was an anomaly.

Compare that to the horror stories many have w.r.t. backup failures that they thought were "robust".  Real time mirroring of your data, secure multi-location storage with robust protocols, background operation requiring no additional work except making sure the connection is live is going to be on average much safer.

I use Google drive since it is cheap and I don't have much music. If I would have more I would try Backblaze. And of course a local copy on a USB-disk.

I would not only use a local disk.
