How do I back up my phone?

Phone backup is nearly automatic now, which means most people assume it's happening and never check. The two failure modes are simple: it was never enabled, or it silently stopped because the cloud storage filled up. Both are found by looking at the last-backup date.

What you'll need

• WiFi connection
• Charger
• Cloud storage subscription if the free tier is full (optional)

Step by step

1. On iPhone: Settings → your name → iCloud → iCloud Backup, and turn it on.It runs automatically when the phone is locked, charging and on WiFi — usually overnight.
2. On Android: Settings → Google → Backup, and turn on Backup by Google One.Exact wording varies by manufacturer, but it's under Google account settings.
3. Check whether photos are included, and enable photo backup separately if needed.iCloud Photos and Google Photos are separate settings from the device backup. This catches a lot of people out.
4. Run a backup manually now and wait for it to complete.Don't wait for the automatic one to discover a problem. Plug in, connect to WiFi and tap 'Back Up Now'.
5. Check the last successful backup date afterwards.This is the actual verification step, and the one people skip. If the date is old, something is failing.
6. If the backup fails, check available cloud storage.Full storage silently stopping backups is the most common failure. Free up space or upgrade the plan.
7. Consider a second copy for anything irreplaceable.Photos you'd be devastated to lose deserve a copy somewhere other than one cloud account — an external drive, or a second service.
8. Recheck the backup date every few months.Put a reminder in the calendar. Backups fail silently, and the discovery moment is always the worst possible time.

Tips

• The standard rule is three copies of anything important, on two different types of media, with one off-site. For photos, cloud plus an external drive gets you most of the way.
• Free cloud tiers are small — 5GB on iCloud, 15GB shared across Google services. A single phone rarely fits, which is why so many backups quietly stop.
• Before changing or selling a phone, back up and then verify by checking the backup date and size.
• Test a restore occasionally if you can. An untested backup is an assumption.

Common mistakes

• Assuming it's working without checking — Backups fail silently. The last-backup date is the only evidence.
• Running out of free cloud storage — Backup simply stops. There's usually a notification, but it's easy to dismiss and forget.
• Assuming photos are in the device backup — They're often a separate setting. Check explicitly.
• Relying on one copy in one service — Account lockouts, accidental deletion and provider issues all happen. Irreplaceable things need a second copy.
