  1. 2-step verification (2SV) ✔
  2. Airplane mode
  3. Auto-play

Why: An online backup is only as safe as the account that holds it. If a criminal signs in, they can delete it. A second step stops a stolen password from being enough.

Huh, didn't know that: NCSC suggests using online storage and an external device together to create two backups.
