    Backup Verification

    Set up a backup once. Test it the rest of your life. Pick your device and walk through the four checks below.

    "Backed up" does not mean "restorable" until you have tested it.

    Most backup failures are silent — the icon says everything is fine, the cloud storage is full, and the backup quietly stopped six months ago. Every story of lost photos starts with "I thought it was backing up." A backup you have never restored from is a hope, not a backup.

    The 3-2-1 rule (worth memorizing)

    3 copies of anything you cannot afford to lose. 2 different types of storage (one local drive, one cloud). 1 copy stored offsite (cloud counts; a USB drive at a relative's house counts). Photos of grandchildren, tax records, scanned medical paperwork — these are the things that need 3-2-1. Cat memes do not.

    External drive verification, no matter the device

    If you back up to a USB drive (Time Machine, File History, manual copies), test the drive twice a year. Plug it in. Open it. Pick three random files from different folders and try to open them. A dead external drive feels exactly like a working one until the moment you need it. Drives last 3-5 years on average — replace before then.

    Quick Tip: put a calendar reminder on the first Sunday of every month titled "Verify backup". Two minutes a month saves a lifetime of memories.
