How to Back up submodules (in 10 minutes a day)

If you have tried Back Up Submodules before and bounced off, the problem is usually ordering, not difficulty. Follow the steps in sequence and verify each one.

Step by step

Handle the common failure: if the verification fails, roll back and re-check the previous step rather than piling on changes.
Prepare the environment: update packages and confirm you have the required permissions before touching configuration.
Make a backup or snapshot of whatever you are about to change, and verify you can restore it.
Verify the change took effect with the relevant status or version command before continuing.
Apply the smallest change that moves you toward the goal — one setting, one file, one command.
Document what you changed and why, so future-you can undo it in minutes.

Tips

Label things; future-you has worse memory than present-you.
Photograph complex assemblies before disassembly.
When stuck, explain the problem out loud — half the time the answer appears.

Common mistakes

Working on the real thing before practicing on a throwaway copy.
Confusing activity with progress — track outputs, not hours.
Quitting during the inevitable plateau instead of scheduling through it.

FAQ

What if I get stuck?

Return to the last verified checkpoint and redo the failing step slowly. If it still fails, search for the exact error or symptom rather than the general task.

Do I need special equipment?

No. The lists above stick to essentials. Upgrade only after the basic version works and you know which limitation actually bothers you.

Can I adapt this to my situation?

Yes — treat the steps as the skeleton. Keep the verification steps; customize everything else.

Once the basics feel automatic, push one variable at a time and keep notes. That is how good becomes great.
