Restic is a great backup program. I use it (via rclone) to back up my laptop and it truly saved my bacon when I attached my main hard disk to a VM I was playing with and accidentally formatted it!
Restic can use rclone to access cloud providers it can't access and that's something we worked together on.
I use rclone directly for backing up media and files which don't change much, but restic nails that incremental backup at the cost of no longer mapping one file to one object on the storage which is where rclone shines.
