Yeah there are plenty of advantages of a full system backup, like not having to worry that you’re backing up all the specific directories needed, and super easy restores since the whole bootable system is saved.
Personally I do both, I have a full system backup to local storage using Proxmox Backup Server, and then to Backblaze B2 using Restic I backup only the really important stuff.
They want to know if you seed well or not, and probably which trackers you use in case some are (more) questionable legal content.
