I use a cloud storage provider to back up via Arq https://arqbackup.com https://arqbackup.com But I don't expect to restore more than a few gigabytes at a time from that. It would take me a week or more to download a terabyte of data. I have very little power over internet connection speed, and there are very few alternatives here. I believe there are two different vendors providing connectivity to our town, and you can pick between four retail resellers. With those limitations, I have tested a full restore process exactly once. That's not good enough. Data at rest on LTO or offline hard disk is something I can control. Distributed offsite storage, too. Restore within 12 hours, I can do that. The downside to tape or cold disk is more in the management of hourly/daily/weekly backups: you have to provision a media rotation schedule, whereas that's sort of built into an online cloud storage service.
