Backing up your chat history

To restore your chat history after transferring your LINE account, you need to back it up beforehand.

Note: Photos and stickers sent in chats cannot be backed up or restored. If there are photos you'd like to save, consider saving them to Albums or Keep.

Before backing up your chats, be sure that:

• You're using the latest version of LINE. (Update the app here.)

• iCloud Drive/Google Drive is turned on.

Note: This feature is unavailable on Android devices that cannot use Google Drive.

• There is enough free space in iCloud Drive/Google Drive.

Note: For information about clearing space in your storage, see this Apple Support page or this Google Drive Help page.

Even if you cannot back up your chat history because your device was lost or stolen, you can automatically transfer your history from the last 14 days if you set a chat history backup PIN. See this Help article for more information.

About the backup PIN

Setting a backup PIN beforehand lets you smoothly transfer your chat history when you transfer your LINE account.

Note: To transfer your chat history in this way, you need to update LINE to version 12.13.0 or later. (Update the app here.)

The amount of chat history that you can transfer will differ depending on whether you backed up your chats beforehand as well as the OS running on your new device.

If you backed up your chats beforehand and are transferring them to a device running the same OS as your old device:

You can restore all the chats you backed up. See this Help article for more information.

If you didn't back up your chats beforehand or are transferring them to a device running a different OS than your old device:

You can transfer the last 14 days of your chat history by following the steps below.

1. From the Home tab, tap Settings > Back up and restore chat history under Backup and transfer.

2. Tap Back up now or Create backup PIN and back up chat history.

3. Enter a six-digit number.

4. Tap the arrow.

When transferring your LINE account to a new device, you'll need the backup PIN you set to restore your chat history. Be sure to write it down so you don’t forget it.

Also, make sure your backup PIN is a secure combination to prevent it from being used by someone else without your permission.

Here are some tips for setting a hard-to-guess backup PIN:

• Don't use consecutive numbers (e.g. 123456).

• Don't use the same number repetitively (e.g. 111111).

• Don't make the PIN your birthday.

I see an error when backing up my chat history

If an error appears when you try to back up your chat history, check to make sure that:

• You're using the latest version of LINE. (Update the app here.)

• You're connected to Google Drive. (See this Google Drive Help page for details.)

• You're logged in to the right Google account.

• There is enough free space in Google Drive.

If an auto-backup fails because you don't have enough free space in Google Drive or on your device, one of the following error messages will appear in a notification from the app or on the settings screen.

Note: You will not receive a notification if an auto-backup fails for another reason.

• Backup failed at XX:XX on MM/DD. Not enough free space in Google Drive.

• Backup failed at XX:XX on MM/DD. Not enough free space on your device.

If you receive a notification like the ones above, or if you find that you cannot do a periodic backup in the LINE app, make sure that you have enough free space in Google Drive and on your device, then try again.

Note: For information about clearing space in Google Drive, see this Google Drive Help page.

We recommend regularly checking the app to make sure your chat history is successfully backed up.

Even if you're unable to back up your chat history to Google Drive, you can transfer your history from the last 14 days if you set a backup PIN beforehand. For the steps to do so, see this Help article.
