How to Back Up Your Phone (iPhone and Android)

Phones get lost, stolen, dropped, and bricked by bad updates, and the single best way to protect everything on yours is to back up your phone before any of that happens. A good backup copies your photos, messages, app data, and settings somewhere safe so you can restore them to the same phone or a brand-new one. This guide covers both iPhone and Android, using cloud backups and local computer backups, and explains exactly what gets saved and how often you should do it.

Cloud backup versus local backup

There are two broad ways to back up a phone, and the strongest plan uses both. A cloud backup sends a copy to the manufacturer’s servers over Wi-Fi, so it runs automatically and survives even if your phone is destroyed. A local backup copies everything to a computer you own, which is fast, free of storage fees, and fully under your control. Cloud backups are effortless; local backups give you a second copy that no subscription or outage can take away.

How to back up an iPhone

iCloud (the automatic way)

Open Settings and tap your name at the top, then choose iCloud and iCloud Backup. Turn on the toggle and tap Back Up Now to run one immediately. Once it is on, your iPhone backs up on its own whenever it is connected to Wi-Fi, plugged into power, and locked, which usually means overnight. To confirm it worked, return to the same screen and check the date and time of the last successful backup.

The catch is space. Apple gives every account only 5GB of free iCloud storage, which fills up fast. If your backup will not complete, you either need to pay for a larger iCloud+ plan or switch to a computer backup, which has no size limit beyond your hard drive.

Mac or PC (the free, unlimited way)

Connect the iPhone to your computer with a cable. On a Mac, open Finder and select the iPhone in the sidebar. On Windows, use the Apple Devices app (older setups used iTunes). Choose to back up to this computer and click Back Up Now. Tick the Encrypt local backup option and set a password if you want the backup to include saved passwords, Wi-Fi details, and Health data, which are left out of unencrypted backups.

How to back up an Android phone

Google backup (built in)

Most Android phones back up through Google. Open Settings and look for a Google or Backup section, confirm which Google account you are using, and turn backup on, then tap Back up now. On Samsung Galaxy phones the path runs through Settings, then Accounts and backup, where you can choose Google Drive and start a backup. Automatic backups then run in the background when the phone is idle, charging, and on Wi-Fi.

Two warnings are worth remembering. First, Google deletes a backup if the phone sits unused for a long stretch (Samsung notes around 57 days of inactivity), so an old backup is not forever. Second, use a real PIN, pattern, or password lock rather than swipe-to-unlock, because that screen lock is what encrypts your backed-up data.

Photos and a computer copy

Google Photos can back up your pictures and videos separately, which is the safest home for your memories since they are often the hardest thing to replace. You can also plug the phone into a Windows PC or Mac and drag your photos, videos, and files straight across for a local copy that does not depend on any account.

Do not forget your chat apps

One of the biggest blind spots in phone backups is messaging apps, which often keep their own separate backup that the system backup does not fully capture. WhatsApp is the classic example: it can save its chat history to iCloud or Google Drive, but only if you turn that on inside the app under its Chats and backup settings. Signal, Telegram, and others each handle this differently. If your conversations matter to you, open each chat app, find its backup option, and switch it on, then set it to run automatically. Losing a phone with a year of unbacked messages is a painful and avoidable mistake.

What actually gets backed up

Not every method saves everything, and the gaps surprise people. The table below shows what each approach typically captures as of 2026; the exact list varies by phone model and software version.

Restoring from a backup

A backup is only useful if you can get it back, so it helps to know how restoring works before you ever need it. On both platforms, you restore during the initial setup of a phone, right after you sign in to your account. A new or freshly reset iPhone offers to restore from an iCloud backup or from a computer, while a new Android phone offers to copy data from a Google backup or from your old device. Pick your most recent backup and the phone rebuilds itself, pulling down apps, settings, and data in the background over the following minutes or hours. Because restoring happens at setup, it is worth confirming your backup is current before you wipe or trade in an old phone, not after.

How often should you back up?

If you leave automatic cloud backups turned on, this takes care of itself: your phone backs up nightly whenever it is charging on Wi-Fi. That is the right setting for almost everyone. On top of that, run a manual computer backup every month or two, and always run one before a big change, such as a software update, a factory reset, or switching to a new phone. A backup you made the day before a disaster is worth far more than a perfect one you never got around to making. It is also smart to test a backup occasionally by checking its date, since a backup that quietly stopped running weeks ago gives you false confidence exactly when you can least afford it.

Keeping your backup safe

A backup is a complete copy of your life, so protect it like one. The account tied to your cloud backup should have a strong, unique password and, crucially, two-factor authentication switched on so no one can reach your data with the password alone. Be wary of emails claiming your iCloud or Google storage is full and demanding you sign in through a link, since that is a classic trap; our guide on how to spot a phishing email shows the warning signs.

A few practical tips

Keep an eye on your free cloud allowance, because a backup that silently stops when storage runs out is worse than no backup at all. If constant backing up seems to drain your battery, that is usually a sign of a different setting gone wrong, and our explainer on why your phone battery drains so fast can help. If your phone is simply too full to back up, clearing space first makes the process smoother, and the same habits that free a phone are different from freeing a computer’s disk space.
