I have been using the rpi "image-utils" to make a full backup - you can run "image-backup" on the running system, which creates a .img file (suitable for re-flashing). The tools will also do full/incremental backups if you're so inclined.
I'll probably use this to make a full backup, in addition to saving my configuration settings (belt *and* suspenders) before wiping and updating to 8.0
