hoppy.network seems like a very expensive Wireguard provider ($8/month for 1TB@100mbit). For that purpose one can spend half that for a VPS with gigabit speeds, even a quarter that during promotions. That provides the same services plus whatever else you can fit to it. What am I missing that they provide?
If you have an offsite copy of your files (and not in a sync service like Dropbox) you are already in a better position than most.
Restoring from offsite takes time, even with Backblaze’s option of shipping a hard disk. You may also have data corruption troubles, companies may close all of sudden. It’s just not as convenient as local copies.
A further copy that is locally available is simply a better strategy. Adding more copies after these two is not a bad idea but you start getting hit by the law of diminishing returns.
