That’s what I personally use, but it’s important to note that Backblaze is meant to be a BACKUP, not “cloud storage” like OP asked about. The goal of backup is just to make sure your local files have a copy somewhere. If somebody’s asking for a cloud storage solution, they’re generally looking for an offsite place to store all their files.
Obviously there’s a lot of grey area, as some cloud storage companies offer “backup” services for some (but not all) of your local files. But in general, these are two different things.
