What version of Signal has this option?
This feature is available on Signal Android 4.17.5 and later.
How do I enable a backup?
- Open Signal.
- Tap on your menu.
- Select Settings.
- Select Chats and media.
- Tap Chat backups.
- Copy the 30-digit passphrase from left to right, top to bottom. You will need this passphrase in order to restore a backup.
- Confirm that you have written down the passphrase.
- Select Enable backups.
- You can confirm whether or not your backup completed succesfully by checking the time of the Last backup.
How do I restore from a backup?
You will only be able to restore your chat history on a new install of Signal. Signal will automatically detect your messages and media from a local backup and ask you to input the 30-digit passphrase prior to registration.
What if I forget my 30-digit passphrase and need to restore messages on a new phone?
Without the passphrase you will be unable to restore a backup. If you have access to the old phone where local backups were enabled and still have your message history displayed in Signal, you can create a new backup with a new password. First, disable chat backups to delete all previous backups on your phone, and then, follow steps above to enable a new backup with a new passphrase.
How do I move messages to my new phone?
- Enable backups on your old phone as listed above.
- Transfer the "Signal" folder stored on your Android phone's external storage from your old phone to your new phone.
- This process varies by phone and OS. This can be enabled on recent versions of Android through the USB settings tab in Android Settings > Storage.
