I use four external multi-TB drives, swap them around every couple of days, and run rsync to copy existing files into a directory with name of the current date and time, with hard links to the previous backup. This gives a live current copy of the existing files, but reduces storage requirements by not duplicating files every time I backup.
Those drives get carried around haphazardly, are often in different physical locations, and usually only differ in content by at most a week of data.
But I'm odd, happy to write my own scripts, and don't want to trust cloud-based solutions for my personal data.
By the way, I regularly pull randomly selected files from the backups to test that they exist and are readable. Backups aren't backups unless you can restore from them, a lesson I learned the hard way three decades ago.
