Android backup settings to check in 2025, step by step

TL;DR:

Turn on Backup by Google One in Settings.
Verify Photos backup and cellular options.
Check app data, SMS, and device settings.
Run a manual “Back up now” before resets.
Test restore on a spare device when possible.

On most phones, go to Settings → Google → Backup. Turn on Backup by Google One, then tap Manage backup to see what is included. Backups can take up to 24 hours on first run.

What gets backed up

Google One backup can include app data, call history, contacts, SMS/MMS, device settings, and some photos if you use Google Photos. Not every app supports full restore of settings, so results can vary by developer.

Photos and videos

Open Google Photos → Profile → Photos settings → Backup. Confirm the right Google account, quality setting, and mobile data options. For large initial uploads, keep the phone on Wi-Fi and on a charger.

Do a manual backup

In Settings → Google → Backup, tap Back up now. Do this before switching phones or a factory reset.

Five settings to verify

Account storage
Make sure the correct Google account is selected for backups in Settings → Google → Backup → Account storage.
App data include list
In Manage backup, confirm apps are included. Some apps require their own cloud sign-in to restore content.
SMS and call history
Check that messages and call logs are toggled on, or use your carrier’s app if you prefer.
Device settings
Wi-Fi passwords, wallpapers, and some permissions sync, but not every toggle is preserved on every device. Expect gaps.
Photos over mobile data
If you have limited data, disable mobile data backing for Photos. Use Wi-Fi only for large uploads.

Restore basics

During setup on a new phone, sign in with the same Google account and choose the latest backup when prompted. After the restore completes, open Google Photos to re-sync media. App sign-ins may still be needed.

Pro tips

Two-step check: After your first backup, visit the Google One app to confirm a recent timestamp.
Charger and Wi-Fi: Leave the device charging overnight for big first backups.
Screenshots of 2FA codes: Do not rely on screenshots. Use an authenticator app with its own cloud backup or recovery keys.

Troubleshooting

Backup stuck: Toggle Backup off and on, then reboot and tap Back up now.
App data missing: Check if the app supports cloud restore. Some apps only save sign-ins, not settings.
Limited storage: Buy more Google One storage or free up space before running a full media backup.
