Hello,

As far as I understand it:
- Backports repository is not intended as an ordinary repo from which you can install all the packages.Its purpose is to let the user install selected packages for which there is a need for a more recent version (option -t). Installing all packages from backports may lead to problems.
- By default your ordinary repo has a 500 priority and backports a 100 priority: when you set up a 500 priority for backports, it means that that backports has priority over your ordinary repo, because the version numbers are higher.
- If your ordinary (Oldstable or Stretch, in your case) repo line (or sources.list.d file) in sources.list mentions "contrib non-free" it is preferable to mention it too for the backports line. Then, generally, if you use a backports kernel, you will want to use also the backports firmwares instead of the ordinary ones.
