Great analysis, but why "per machine"? I back up data, not machines. I would prefer that third party backup software not have access to the unencrypted files on my machines. The pricing you mention is compelling. Which service is that? Does your model work if the data is on multiple external drives? Getting down to a specific example, say I have one laptop and three external drives. Do the backup services you have in mind work with this setup? How would they charge?

The service I use is the CrashPlan "family" plan. If I would just gather all the data to one machine instead it would work too (could just keep it on a file server with a directory per machine or whatever). The only reason "machines" are useful is for having separate easy restores -- basically my parents or mother in law can restore their machines from the other side of the country. As long as you just keep the external drives connected to the same machine during backup, the backup application doesn't care where the file set to backup is mounted. its just a directory list per machine. I used to backup "data" too, by using a first step of backup of multiple machines to a NAS and then only backup that data to the cloud. However, I sacrificed that extra security for the added convenience of direct restore of individual files and machines. It also reduced the risk of me having done a mistake in the backup config of the first step (which I estimated to be a way higher risk than hardware failure, fire or a data breach at the cloud provider, since I have basically never configured anything right). Being able to easily fetch an individual file from 1 day or 1 week ago can really save time. Edit: also remember that the backup client on Linux uses ram proportional to the backup size so on my cheapo NAS I also outgrew its ram and would have had to get a faster one or a file server, that was also partly why I left it. The good thing about the backup pricing is that it doesn't increase with aggregated backups like normal storage. It's 150/year so to be competitive you need a few TB, but you can very easily backup your parents machines too and save some time around Christmas... Note though that people sharing the same plan can see each others data (or so I presume)
