Switching phones or resetting an Android device always raises the same question: will everything come back afterward?
The short answer is that Google Drive backup on Android, now usually called Backup by Google One, can save your apps, contacts, call history, device settings, and text messages to your Google Account. Photos and videos are handled separately through Google Photos.
This article covers where to find the backup settings, what each one actually includes, how to confirm a backup is current before switching phones, and what to do if a backup stalls.

🔍 What to Check First
Before turning anything on, confirm which Google Account is signed in on the phone. Backup is tied to that account, so if multiple accounts are present, it matters which one holds the backup.
Check that the phone has a stable internet connection, ideally Wi-Fi, since automatic backups typically run over Wi-Fi when the phone is idle and charging.
It also helps to know roughly how much storage the account has, since backup data counts against the same storage pool used by Google Photos and Drive files, depending on the account and plan.
Finally, note the Android version and phone manufacturer. Menu names and exact locations can differ, and the fastest way to find the setting is to search for it rather than memorize a fixed path.
💡 Key point: Backup is linked to whichever Google Account is active on the phone, so confirm the correct account before assuming a backup exists.
⚙️ Step-by-Step: Turning On Backup
On most Android phones, the backup setting lives inside the Google section of system settings. If the exact wording differs on a particular device, searching Backup inside the Settings search bar usually surfaces it.
- Open Settings.
- Tap Google, then All services, then Backup. On some phones, Backup appears directly under Google without the extra step.
- If prompted, choose Backup by Google One and follow the setup prompts.
- Select the data types to back up, if the phone offers a choice, then turn on Backup by Google One.
- To start a backup immediately instead of waiting for the automatic schedule, tap Back up now.
After turning it on, return to Settings → Google → All services → Backup and open Backup details to see exactly what is included and when the last backup ran.
Google notes that a backup can take up to 24 hours to finish, so a freshly enabled backup may not show a completed status right away. This is normal and does not necessarily mean something is wrong.
Since backup setup involves a Google Account and personal device data, check the service’s official help page or contact Google support if any step looks different from what is described here.
📱 What Gets Backed Up, and What Does Not
Depending on the device and settings, a device backup may include apps and app data, call history, contacts, device settings, and SMS/MMS messages.
This is different from simply uploading every file on the phone to Drive. A device backup is a structured snapshot of system-level data, not a copy of a folder.
Photos and videos are not part of this backup system at all. They are handled through Google Photos, which has its own separate backup setting that needs to be checked independently.
For individual files, documents, or folders stored on the phone, those need to be uploaded manually using the Drive app’s upload option. Device backup and file upload are two different processes, even though both ultimately store data in the same Google Account.

📊 Samsung and Other Manufacturer Differences
Menu names and locations differ by Android version and phone manufacturer, which can make the same feature look like it is missing when it has simply moved.
Samsung phones are a common example. Instead of a single Google → Backup path, Samsung devices may show related options under Settings → Accounts and backup, sometimes alongside a separate Samsung Cloud backup option.
Having two backup systems on the same phone, Google’s and the manufacturer’s, is not unusual. It is worth checking both if restoring data later does not look complete, since each one may store different categories of data.
| Phone Type | Typical Path | Notes |
|---|---|---|
| Most Android phones | Settings → Google → All services → Backup | Backup by Google One |
| Samsung phones | Settings → Accounts and backup | May also show a separate manufacturer cloud backup |
| Any device, unsure | Settings search bar | Search Backup to find the renamed menu |
The data types available to back up can also vary by device and configuration, so one phone might offer more granular choices than another even on the same Android version.
✅ Confirming Your Backup Before Switching Phones
Before resetting an old phone or activating a new one, it is a good idea to verify the backup status rather than assume it is current.
Open Settings → Google → All services → Backup and check Backup details for the timestamp of the last successful backup. If it shows a date from months earlier, backup may have stopped working without an obvious notification.
Also confirm that the account shown in Backup details is the same Google Account planned for use on the new phone. A backup saved under one account will not automatically appear if a different account is signed in later.
For photos and videos, check Google Photos backup settings separately, since those are not reflected in the device backup status screen at all.
⚠️ Watch out: A device backup only restores automatically during the initial setup of a new or factory-reset phone. It does not work as a full restore triggered from within an already set-up phone’s settings.
🛡️ Restoring a Backup on a New or Reset Phone
To restore, sign in to the same Google Account while setting up a new or factory-reset Android phone, then follow the restore prompts that appear during setup.
Photos and videos backed up to Google Photos are available separately through the Google Photos app once signed in, rather than being pulled into the device during the setup restore step.
Restoring depends on the device and Android version. Google cautions that restoring a backup made on a newer Android version to an older one may be incomplete, so matching or newer software on the receiving phone generally works more smoothly.
Because this step involves personal account data, it is worth reviewing the official Google support page for backup and restore if the setup screen presents unexpected options or an error.
⚠️ If Backup Is Not Working
If a backup is not progressing, start with the basics: confirm the phone is online, preferably on Wi-Fi, and that it is charged, since automatic backups typically require both conditions along with an idle phone.
Next, confirm that Backup by Google One is actually turned on and not just visited once without completing setup. Revisit Settings → Google → All services → Backup and check the toggle state directly.
Review Backup details for the status message and the list of selected data types. Sometimes a specific data type, such as call history or SMS, is unchecked even though the overall backup toggle is on.
If none of that resolves it, tapping Back up now manually can sometimes restart a stalled process, though it may still take time to finish given the up-to-24-hour window Google describes for completion.
📌 Things to Watch Out For
One common mix-up is assuming that turning on device backup also backs up every photo, video, and downloaded file. It does not; Google Photos and the Drive upload feature handle those separately.
Another is checking backup status right after enabling it and concluding it failed, when in fact it may simply still be processing within the normal completion window.
It is also worth remembering that restoring is designed around the setup flow of a new or reset device. Looking for a restore button inside an already-configured phone’s settings will not produce the same result.
Before resetting or replacing a phone, verifying that its backup is both recent and linked to the correct Google Account remains the simplest way to avoid losing contacts, messages, or settings in the transition.
🙋 Frequently Asked Questions
Q. Does turning on device backup also back up photos automatically?
No. Device backup covers things like apps, contacts, call history, device settings, and SMS/MMS messages, but photos and videos are backed up separately through Google Photos.
Q. How much Google Account storage does a device backup use?
There is no fixed figure, since this can vary by device and the amount of data involved; checking the account’s storage details directly is the most reliable way to confirm current usage.
Q. Can backup run over mobile data instead of Wi-Fi?
Automatic backups typically happen over Wi-Fi when the phone is idle and charging; checking the specific phone’s backup settings is the best way to confirm whether a mobile data option exists on that device.
Q. What happens if two different Google Accounts are used on the old and new phone?
Since backup is tied to a specific Google Account, data backed up under one account generally will not appear unless that same account is signed in on the new phone during setup.
Q. Is Samsung Cloud the same as Google’s device backup?
No, they are separate systems. Samsung phones may offer both, often under Settings → Accounts and backup, and each can store different categories of data.
Q. Can a backup be restored onto a phone that is already set up?
Generally, the full device backup is restored during the initial setup of a new or reset phone, not from within an already-configured phone’s settings.
Q. Will restoring work if the new phone runs an older Android version than the old one?
Google cautions that restoring a backup made on a newer Android version onto an older one may be incomplete, so this scenario carries extra uncertainty.
