Premium Backup lets you back up your chat history in real time, including photos and videos, to 100 GB of storage provided by LINE. It is only available to LYP Premium (Japan) and LINE Premium (Thailand) members.

Moreover, using Premium Backup allows you to transfer more than the last 14 days of chat history (including text messages), even when transferring your LINE account between devices with different operating systems (e.g. Android to iOS, iOS to Android).

Chat history data that might not be backed up
In some cases, the following chat history data might not be backed up.

• Messages from official accounts and system messages
• Photos, videos, files, and voice messages that expired before using Premium Backup
• Some photos, videos, files, and voice messages shared before using Premium Backup

Your deleted chat history
If you delete a chat, its chat history will also be deleted at the same time. Since it's no longer saved in your chat history, backing up your chat history afterward won't recover it.

Your chat history if you haven't opened LINE for 14 days or more
If you don't open LINE for 14 days or more, chat history that expired within that time frame is also backed up.
Note: To check the chat history for this period, you need to restore it with a method detailed in Restoring your backed up chat history. The chat history for that period will also be restored when restoring chat history in scenarios such as changing devices.

How to start using Premium Backup:
Check the size of your chat history and your device's storage
With Premium Backup, you can back up a maximum of 100 GB of chat history. Also, you need at least 5 GB of free space on your device when performing an initial backup. The backup will automatically stop if your device storage falls below 3 GB during the initial backup.

Please check if you have enough storage for the backup using the methods below.

• To check the size of your chat history, tap the Home tab > Settings

> Chats > Delete data.
• To check your device's storage, see the following links based on the OS you're using.
