The simplest way: use Google Account backup

The easiest backup method on Android is the one already built in. When you set up your Android phone with a Google Account, the phone automatically backs up your contacts, calendar events, app data, and device settings to Google's servers. You do not have to do anything — it happens in the background when your phone is plugged in and connected to Wi-Fi.

To check that this automatic backup is turned on, open Settings, then tap Google (or Accounts on some phones), then Manage your Google Account. Tap the Backup tab. You should see a list of what is being backed up — contacts, calendar, Gmail, photos in Google Photos, and app data. If the toggle next to Backup by Google One is off, turn it on.

This backup covers the essentials, but it does not include photos and videos stored on your phone's internal storage — only photos you have uploaded to Google Photos. If you want those backed up too, you need a second step.

Key Takeaways

  • Google Account backup happens automatically and covers contacts, calendar, app data, and settings, but not photos stored on your phone.
  • Google Photos backs up your photos and videos separately, and you can set it to back up automatically whenever your phone is on Wi-Fi.
  • If you want to back up everything including photos, messages, and call logs, use Samsung Cloud (on Samsung phones) or a third-party app like Titanium Backup.
  • You can restore from a backup when you set up a new phone by signing in with the same Google Account you used on the old phone.
  • External storage backups using a USB cable or SD card give you a copy you control, separate from cloud services.

Back up photos and videos with Google Photos

Photos and videos need their own backup because Google Account backup does not include them. The standard way to back them up is Google Photos, which is a free app that comes on most Android phones.

Open Google Photos and tap your profile picture in the top right corner. Tap Photos settings, then Backup and sync. Turn on the toggle for Backup and sync. Choose your upload quality — Original quality uses your Google Drive storage (15 GB free), while Storage saver compresses photos slightly and gives you unlimited storage. For most people, Storage saver is the right choice.

Once backup is on, Google Photos will upload your photos and videos whenever your phone is connected to Wi-Fi and plugged in. You can also tap Back up now to upload when ready. The app will show you a count of how many photos are backed up at the top of the screen.

Full backup on Samsung phones using Samsung Cloud

If you own a Samsung phone, you have a second option: Samsung Cloud. This service backs up more than Google does — it includes messages, call logs, home screen layout, and some app data in addition to contacts and calendar.

Open Settings, then tap Accounts and backup (or Samsung Cloud on some models). Tap Backup. You will see a list of what can be backed up. Check the boxes next to the items you want — typically contacts, messages, call logs, and settings. Tap Back up now. The backup will run in the background and may take several minutes depending on how much data you have.

Samsung Cloud gives you 5 GB of free storage. If you need more, you can pay for additional storage, but for most people the free tier is enough for contacts, messages, and settings. Photos still need to be backed up separately through Google Photos or Samsung's Gallery app.

Back up everything with a USB cable or SD card

If you want a backup that lives on your computer or an external card — one you control completely, separate from any cloud service — you can copy files directly using a USB cable or SD card.

Using a USB cable: Connect your phone to a computer with a USB cable. On your phone, you may see a notification asking what you want to do — tap File Transfer or Transfer Files. On your computer, your phone will appear as a drive or folder. Open it and navigate to DCIM (for photos and videos) or Documents (for files). Drag the folders you want to your computer's backup location.

Using an SD card: If your phone has an SD card slot, insert a microSD card. Open Settings, then Storage, then SD card. Tap the menu icon (three dots) and select Move media files or Format as internal storage. The second option treats the card as part of your phone's storage, so new photos automatically save there. The first option lets you move existing photos to the card manually.

A USB or SD card backup is slower than cloud backup and requires you to remember to do it, but it gives you a copy that does not depend on any online service staying available or keeping your account active.

Restore from backup when you get a new phone

When you set up a new Android phone, the setup wizard will ask you to sign in with a Google Account. Use the same account you used on your old phone. The phone will then ask whether you want to restore from backup — tap Yes or Restore.

The phone will read your contacts, calendar, app data, and settings from Google's servers. Apps themselves will reinstall from the Google Play Store. This process can take 10 to 30 minutes depending on how much data you have and your internet speed. Leave the phone plugged in and connected to Wi-Fi while it restores.

Photos from Google Photos will not automatically appear on your new phone — you need to open Google Photos and they will read in the background. Messages and call logs do not restore automatically through Google backup; if you backed those up through Samsung Cloud or another service, open that app and restore from there.

Third-party backup apps for advanced users

If you need to back up text messages, call logs, or app data in a way that Google does not cover, third-party apps like Titanium Backup or Swift Backup can do more detailed backups. These apps create a complete copy of your apps and their data that you can restore later.

These apps require your phone to be in Developer Mode, which is a setting most people do not need to change. They are useful if you switch phones frequently, want to keep a backup separate from Google, or need to restore specific app data. For most people, Google Account backup plus Google Photos is enough.

What does and does not get backed up

Understanding what each backup method covers helps you know whether you need multiple backups. Google Account backup covers contacts, calendar, Gmail, app data, and device settings. Google Photos covers photos and videos. Samsung Cloud adds messages, call logs, and home screen layout. USB or SD card backups copy whatever files you select manually.

What does not get backed up by any of these methods: text messages (unless you use Samsung Cloud or a third-party app), call logs (same), voicemails, some app data from apps that do not support cloud backup, and files stored in app-specific folders that are not synced. If any of these matter to you, check whether your phone manufacturer offers a more complete backup service, or use a third-party app.

Frequently Asked Questions

How much does Google backup cost?

Google Account backup is free. Google Photos with Storage saver quality is also free and unlimited. If you choose Original quality in Google Photos, it uses your Google Drive storage, which gives you 15 GB free across Gmail, Drive, and Photos combined. After that, you pay for additional storage, but most people never reach that limit.

Can I back up to multiple services at the same time?

Yes. You can use Google Account backup, Google Photos, and Samsung Cloud all at the same time without any conflict. Each backs up different things, so having all three running gives you the most complete backup. You can also add a USB or SD card backup on top of these.

What happens to my backup if I delete my Google Account?

If you delete your Google Account, your backup data on Google's servers will be deleted after 20 days. If you have photos in Google Photos, those will be deleted too. Before deleting an account, read your data or move it to another service. You can request a copy of all your data from Google Takeout.

Do I need to back up my apps?

No. When you restore from a Google Account backup on a new phone, the Google Play Store automatically reinstalls your apps. You do not need to back up the apps themselves. However, if an app has been removed from the Play Store, you cannot reinstall it this way — in that case, a third-party backup app like Titanium Backup can preserve the app file itself.

How often should I back up my phone?

Google Account backup and Google Photos run automatically, so you do not have to think about them. If you use Samsung Cloud, back up at least once a week or whenever you have important new data. If you use USB or SD card backups, do them monthly or whenever you have photos or files you cannot afford to lose.
