Fully agree, Borg is awesome. I wrote up how I'm using it here[1]. In short, borg backup to a local machine, and that machine uses rclone to copy the backups to an S3 bucket off-site. I've had multiple occasions to restore stuff successfully, and I never have to think about whether my data is retrievable.
