The problem is, who guarantees the guarantors?
With this, you have nothing.
I had an older family member ask me "are you sure it won't go anywhere?" while I was encouraging them to use cloud storage such as Dropbox or Google Drive rather than a flash drive.
While I had naively never given it that much thought before, I wasn't sure the answer was "yes"— specifically that, if Dropbox or Google Drive were to shut down, they would give users the opportunity to take their files out.
I tried searching through their ToS but couldn't find any guarantees.
But in this case, I think ToS are insufficient, unless backed by physics - specific guarantees and allocated (escrow) funds, or insurance, for example, to purchase the replacement.
And sometimes you need to put a level of trust in a service. I've sent things off to be scanned because, realistically, it was never going to happen otherwise and I really wanted to get the materials into digital form.
Very true, think of all the people using cloud-first tools like Google Docs or Google Sheets - how many bother to download/backup those files?
Also, it's guaranteed to be small (2 GB) so it's easy to backup.
