How WhatsApp backup works
WhatsApp does not keep your chat history on its servers. Instead, on Android, it saves a copy of your chats and media to your Google Account on a schedule you choose. When you install WhatsApp on a new phone and verify the same number, it finds that backup and offers to restore it.
| Item | Included in backup? |
|---|---|
| Text messages | Yes |
| Photos and voice notes | Yes |
| Videos | Optional (you choose) |
| Call history | Yes, as part of chats |
| Messages received after the last backup | No, until the next backup |
Set up automatic backup
- Open WhatsApp and tap the three dots > Settings.
- Tap Chats > Chat backup.
- Choose the Google Account to back up to.
- Set Back up to Google Account (frequency) to Daily.
- Choose whether to include videos and whether to back up over mobile data.
- Tap Back up to create the first backup now.
Tip: Leave “include videos” off if your Google storage is limited. Videos are usually the largest part of a backup.
Restore chats on a new phone
- On the new phone, add the same Google Account that holds the backup.
- Install WhatsApp from Google Play.
- Verify your same phone number.
- When WhatsApp finds the backup, tap Restore.
- Wait for the restore to finish, then tap Next. Media keeps downloading in the background.
Important: restore only works with the same phone number and Google Account used for the backup. Back up on the old phone right before switching to include your latest messages.
Encrypted backups
WhatsApp offers end-to-end encrypted backups. When turned on (in Chat backup > End-to-end encrypted backup), nobody, including WhatsApp or Google, can read your backup. You protect it with a password or a 64-digit key. Store this carefully: if you lose it, WhatsApp cannot help you recover the backup.
Fix common backup problems
| Problem | Try this |
|---|---|
| Backup stuck at 0% or not finishing | Use stable Wi-Fi, keep the phone charging, update WhatsApp |
| “Google storage full” | Free space in Google Drive/Photos or exclude videos |
| Backup not found when restoring | Check you are using the same number and Google Account |
| Old messages missing after restore | They were received after the last backup |
| Encrypted backup password forgotten | The backup cannot be restored; start a new backup |
