Quick answer: Turn on automatic cloud backup, confirm that your photos and contacts are syncing, and keep a second copy of important files somewhere separate from your phone.
A phone can be lost, stolen, damaged, or locked out without warning. A backup means your photos, contacts, messages, and important files are not tied to one physical device.
What you should back up
Prioritise:
- Photos and videos
- Contacts
- Messages
- Calendars and notes
- Important documents
- WhatsApp or other messaging app data
- Two-factor authentication recovery codes
- Device settings and app data
A backup does not always include everything automatically. Check each service separately.
Back up an iPhone with iCloud.
- Connect the iPhone to Wi-Fi.
- Open Settings and tap your name.
- Tap iCloud → iCloud Backup.
- Turn on Backup this iPhone.
- Tap Back Up Now to create an immediate backup.
For automatic backups to work, the iPhone normally needs to be connected to Wi-Fi, charging, and locked. Check the time of the last successful backup before assuming it worked.
Back up Android with Google.
- Open Settings.
- Search for Backup.
- Open the backup settings and turn on Google backup.
- Confirm the Google account being used.
- Start a manual backup if your device provides that option.
The exact menu varies by manufacturer. Samsung phones may also offer Samsung Cloud or Smart Switch options.
Back up photos separately.
Cloud device backup and photo backup are not always the same thing.
- iPhone: Check Settings → [your name] → iCloud → Photos.
- Android: Open Google Photos, tap your profile picture, and check Photos settings → Backup.
Confirm that the backup is complete before deleting local photos.
Backup WhatsApp
Open WhatsApp and go to its Settings → Chats → Chat backup area. Choose the correct cloud account, set a backup frequency, and include videos only if you have enough storage.
Make sure you know the phone number and account credentials needed to restore the backup.
Keep a second copy of important files.
Cloud backup is useful, but a second copy protects you from account problems, accidental deletion, or storage limits. Export irreplaceable photos and documents to a computer or external drive periodically.
Keep the second copy separate from the phone. A drive carried in the same bag as your phone will not help if both are lost together.
Protect your backup account.
Your backup is only as secure as the account that controls it.
- Use a unique password.
- Turn on two-factor authentication.
- Save recovery codes somewhere safe.
- Review logged-in devices.
- Do not share verification codes.
Our guides on two-factor authentication and password managers can help.
Test the backup.
A backup is not confirmed until you know it can be restored. Check the most recent backup date and confirm that important photos and files appear in the relevant cloud service. If possible, test restoration on an old device or through the service’s web interface.
Final verdict
Turn on automatic backup today, then create a second copy of your most important files. The best backup is one that runs automatically, protects your account, and has been checked before you need it.
