Android backs up your data automatically, but you need to turn it on and check what's actually being saved

Android devices back up contacts, calendar events, app data, and some settings to your Google Account automatically — but only if you have turned on backup and you are signed into Google. The backup happens in the background when your phone is plugged in, connected to Wi-Fi, and locked. Photos and videos do not back up this way by default; they need a separate service like Google Photos. Text messages, call logs, and some app data may or may not back up depending on which apps you use and whether those apps support backup.

The first step is to check whether backup is already running. Open Settings, scroll to Accounts, tap Google, select your account, then look for Manage Your Google Account. Tap the Backup tab. If you see a green checkmark next to "Backup by Google One" or "Back up to Google Account", backup is on. If the toggle is off or grayed out, you need to turn it on. You will see a list of what Android is backing up — contacts, calendar, Gmail settings, and similar items. Photos and videos will not appear on this list because they use Google Photos instead.

Key Takeaways

  • Google Account backup saves contacts, calendar, and app data automatically when your phone is plugged in and on Wi-Fi, but you must turn it on first in Settings under Accounts.
  • Photos and videos require Google Photos, which you can set to back up automatically, and you can choose whether to store them at original quality or compressed quality.
  • Text messages and call logs do not back up to Google Account by default; you need to use a separate app or export them manually if you want to keep them.
  • When you get a new Android phone and sign into the same Google Account, backed-up data restores automatically during setup, but photos and videos restore only if you have Google Photos installed.

Turn on Google Account backup in Settings

Open the Settings app on your Android phone. Scroll down and tap Accounts (on some phones it says Users and Accounts). Tap Google. You should see your Google Account email address listed. Tap it. Now tap Manage Your Google Account at the top. Swipe to the Backup tab.

Look for the option that says "Back up to Google Account" or "Backup by Google One". If a toggle switch appears next to it, make sure the toggle is turned on (it should be blue or green, not gray). If you see a message saying backup is already on, you are done with this step. If you see a message saying you need to set up backup, tap the option to turn it on. Android will ask you to confirm your Google password. Enter it and tap Next.

Once backup is on, Android will back up your data the next time your phone is plugged in, locked, and connected to Wi-Fi. You do not need to do anything else — it happens automatically in the background.

Set up Google Photos to back up your photos and videos

Google Account backup does not include photos or videos. To back those up, you need Google Photos, which is a separate app. If you do not already have it, open the Google Play Store, search for Google Photos, and install it. If you already have it, open the app.

Tap your profile picture in the top right corner. Tap Photos settings. Tap Backup and sync. Make sure the toggle is turned on. Below that, you will see Storage saving options. Choose Original quality if you want your photos backed up exactly as they are (this uses more of your Google storage). Choose Storage saver if you want Google to compress them to save space (most people cannot see the difference, and this does not count against your storage limit). Tap Backup device folders if you want to back up photos from folders other than your main camera folder.

Google Photos will now back up your photos and videos whenever your phone is connected to Wi-Fi. The first backup may take several hours if you have many photos. You can check the progress by opening Google Photos and looking at the top of the screen.

Back up text messages and call logs manually

Android does not automatically back up text messages or call logs to your Google Account. If you want to keep these, you have two options: use a third-party app or export them manually.

The easiest option is to use an app like SMS Backup+ (free, available in the Google Play Store). Install it, sign into your Google Account, and let it back up your text messages to Gmail. Your messages will be searchable in Gmail and will restore automatically if you get a new phone and sign into the same account. For call logs, some phones have a built-in export option in the Phone app — open Phone, tap the three-dot menu, look for Settings or Call history, and see if an Export option appears.

If you prefer not to use a third-party app, you can export text messages manually by opening your Messages app, long-pressing a conversation, and looking for an Export or Share option. Not all messaging apps have this feature. Check your specific app's settings to see what options are available.

Restore your data on a new Android phone

When you set up a new Android phone, the setup wizard will ask you to sign into your Google Account. Use the same account you backed up to. During setup, Android will ask whether you want to restore your backed-up data. Tap Yes. Android will restore your contacts, calendar, app data, and settings automatically.

Photos and videos will not restore during setup unless you have Google Photos installed. After you finish the initial setup, open the Google Play Store, install Google Photos, and sign into the same Google Account. Your photos and videos will appear in the app within a few minutes (or longer if you have many). They are already backed up in the cloud, so they will not read to your phone unless you open them.

Text messages and call logs will not restore unless you used an app like SMS Backup+ to back them up. If you did, open that app on your new phone, sign into your Google Account, and it will restore your messages automatically.

Check how much storage you are using

Google gives you 15 GB of free storage for backups, photos, videos, and Gmail combined. If you choose Original quality in Google Photos, your photos and videos count against this limit. If you choose Storage saver, they do not. You can check how much storage you are using by opening Settings, tapping Accounts, tapping Google, tapping Manage Your Google Account, and swiping to the Storage tab.

If you are running out of space, you have a few options. Delete old photos or videos you no longer need. Switch Google Photos to Storage saver quality for future backups (this does not change photos already backed up). Or pay for more storage — Google One plans start at $1.99 per month for 100 GB. You can also delete old Gmail messages or clear out old app data to free up space.

What happens if you do not back up your phone

If your phone is lost, stolen, or stops working, any data that is not backed up is gone. This includes photos, videos, text messages, call logs, and any data stored only on your phone. Contacts and calendar events are usually safe because most people use Gmail or another online service for these. But anything stored only locally — like photos you took but never uploaded, or text conversations — will be lost.

Backup takes almost no effort once you turn it on. Your phone backs up automatically in the background. The only thing you need to remember is to keep your phone plugged in and on Wi-Fi occasionally so the backup can complete. If you travel or are away from Wi-Fi for long periods, plug your phone in when you get home or to a place with Wi-Fi so your recent data gets backed up.

Frequently Asked Questions

Does backup use my phone's data plan?

No. Backup only happens when your phone is connected to Wi-Fi, not on cellular data. If you want to back up while away from home, you can manually trigger a backup over Wi-Fi at a coffee shop or library, but it will not happen automatically over cellular.

Can I back up to a computer instead of Google?

Android does not have a built-in way to back up to a computer the way iPhones do with iTunes. You can use Google's backup, or you can use third-party apps that back up to cloud services like Dropbox or OneDrive. Google's backup is the simplest option because it works automatically and restores to any new Android phone you sign into.

What if I do not have a Google Account?

You need a Google Account to use Android backup. If you do not have one, go to accounts.google.com and create one for free. You will need an email address (you can create a Gmail address as part of the signup). Once you have an account, sign into it on your phone and follow the backup steps above.

Will my apps restore on a new phone?

Yes, but only if you sign into the same Google Account. When you set up a new phone and sign in, Google Play will automatically install all the apps you had on your old phone. This can take a while if you have many apps. You can also manually install apps by opening the Play Store and tapping your profile picture, then Manage apps and device, then Manage to see all your installed apps.

How often does backup happen?

Android backs up once per day when your phone is plugged in, locked, and on Wi-Fi. You cannot change this schedule. If you want to back up more frequently, you can manually trigger a backup by going to Settings, Accounts, Google, your account, Manage Your Google Account, Backup tab, and tapping the three-dot menu to see if a manual backup option appears (this varies by phone model).
