I doubt it's the perfect backup set-up, but I've been able to do regular restore tests. I have a Synology NAS which has a Borg community package. I use BorgBase for remote backups, and have another local backup on one of the volumes in the NAS. I keep dailies for a week, monthlies for a year and three yearlies, with automatic pruning. Once a year, I do my best to back-up my most important stuff on DVDs, but I'm not a very disciplined person. I keep them on a spindle, which is also probably bad practice.
