The simple backup routine that survives a lost phone

In brief

A backup is a second copy of your photos, documents and messages, kept somewhere the original problem cannot reach. The routine that works for most people has three parts: automatic cloud backup for your phone, automatic backup for your computer, and one copy that is not connected to anything. Set it up once, check it twice a year, and a lost device becomes an inconvenience rather than a loss.

Step one: turn on your phone's own backup

Both major phone platforms include a backup service that runs on its own when the phone is charging and on Wi-Fi. On an iPhone it is iCloud Backup, on Android it is Google One backup, each found under the phone's settings. Photos usually need their own switch: iCloud Photos or Google Photos. Check that it has actually completed recently rather than assuming; a full storage plan quietly stops backups, and the phone will tell you if you look.

Step two: back up the computer automatically

Manual backups are the ones that never happen, so choose something that runs by itself. Windows and macOS both include a built-in tool that backs up to an external drive whenever it is plugged in, and a cloud service such as OneDrive, iCloud Drive, Google Drive or a dedicated backup service can keep a continuous copy of your important folders. Point it at the folders that matter, documents, photos, desktop, and let it run.

Step three: keep one copy offline

Cloud backups protect against a lost or broken device. They do less against ransomware or an account takeover, because anything that can reach your files can often reach the synced copy too. The answer is one copy that is disconnected most of the time: an external drive you plug in monthly, copy to, and unplug. Keep it somewhere other than next to the computer if you can.

The rule to remember

Backup professionals call it 3-2-1: three copies of anything you care about, on two different kinds of storage, with one somewhere else. The routine above gets you there without much thought: the original, the cloud copy, and the offline drive.

Test it before you need it

A backup you have never restored from is a hope, not a plan. Once a year, pick a file and restore it from the cloud, then from the drive. Make sure you know the password for the backup account, and that the account itself has two-step sign-in, because whoever controls that account controls every copy.

If you only do one thing

Turn on the phone backup and check it has finished. For most people, the phone holds the photos that cannot be replaced, and that switch takes thirty seconds.
