Over the years, I've used both CCC and SuperDuper in order to have bootable backups. I've always used these in addition to TimeMachine though. I currently use TM to both my TrueNAS server and to a local disk (when I remember to plug it in). I use Arq to B2 for my home directory. For my family, I have them use Backblaze. It's the only thing I've found that's really set and forget. They never remember to plug in a local TM drive. And setting up TM with a network drive, it flakes out every few months, then they just ignore the messages from TM that their drive isn't being backed up. Backblaze pretty much Just Works. And it sends me an email report once a week. A full restore via Backblaze would be a bit painful. But it's better than no backup at all.
