Make the next step obvious
A useful checklist records decisions, not just tasks. Write down what success looks like, where the source material lives, and which check confirms the result. Keep each step small enough to finish without remembering an unwritten instruction.
Backups need a return journey
A copy is only useful if it can be restored. Keep an independent copy of important files, retain previous versions, and occasionally restore a small sample into a separate folder. Record the recovery steps alongside the backup schedule.
