    The 3-2-1 backup rule

    ~15s
    Keep 3 copies of your data, on 2 different types of storage, with 1 copy offsite (cloud). This protects against hardware failure, theft, fire, and ransomware. It sounds complicated but it's straightforward.
    2

    Copy 1: Your original files

    ~15s
    The files on your computer, phone, or tablet. This is what you use every day. It's not a backup — it's the primary copy that everything else protects.
    3

    Copy 2: Local backup

    ~15s
    An external hard drive ($40-80 for 1-2 TB). Windows: File History or Windows Backup. Mac: Time Machine. Set it up once and it backs up automatically when the drive is connected.
    4

    Copy 3: Cloud backup

    ~15s
    Automatic cloud backup protects against fire, theft, and local disasters. Backblaze ($9/month): unlimited backup for one computer. iCloud, Google Drive, or OneDrive for specific folders and photos.
    5

    What to back up

    ~15s
    Documents, photos, and videos are irreplaceable — back these up first. Financial records and tax documents. Contacts and email. Anything you'd be devastated to lose. Programs can be reinstalled; personal files can't.
    6

    Phone backup

    ~15s
    iPhone: Settings > Your Name > iCloud > iCloud Backup. Backs up automatically over Wi-Fi. Android: Settings > Google > Backup. Google One backups include photos, contacts, and app data.
    7

    Test your backups

    ~15s
    A backup you've never tested might not work when you need it. Periodically try restoring a file from your backup to verify it's working. Check that cloud backups are running (look for last backup date in settings).
    8

    Don't forget passwords

    ~15s
    Back up your password manager vault. If you use browser-saved passwords, make sure they sync to the cloud. Keep your master password written down in a secure physical location.
