As of 2026, LINE remains one of the most widely used messaging apps in Japan, with approximately 97 million active users. Daily conversations, business communications, and family memories — all accumulate within LINE. However, the backup features designed to protect this valuable data still have significant gaps. This article covers the latest state of LINE backup in 2026, each feature's limitations, and how ChatArchive provides a comprehensive solution.
1. Standard Backup: Current State
LINE's Standard Backup saves chat history to iCloud Drive (iOS) or Google Drive (Android). It's a free feature, and as of 2026, the basic mechanism remains unchanged.
Text Messages Only
Standard Backup saves text messages only. Photos, videos, voice messages, stickers, and file attachments are not backed up at all. Precious photos shared with friends and family could vanish when you switch devices.
Cloud Storage Dependent
If your iCloud or Google Drive runs out of space, the backup fails. iCloud's free tier is limited to just 5GB, and it's often consumed by photos and other app data. Many users find themselves forced to upgrade to a paid plan solely to back up LINE.
Manual Execution and Automation Limits
Standard Backup is primarily manual. While an automatic backup setting exists, it requires both a Wi-Fi connection and charging — with no guarantee it will actually run. If you forget to back up before switching phones, every message since your last backup is permanently lost.
2. Premium Backup (LYP Premium): Latest Updates
Premium Backup is an enhanced backup feature offered as part of LYP Premium (the merged Yahoo! Premium/LINE Premium service). It addresses many Standard Backup weaknesses, but comes with its own constraints.
Real-Time Backup
Premium Backup automatically saves messages — including photos and videos — in real time. No manual action required; every message sent or received is backed up automatically.
100GB Storage Limit
Despite its advantages, Premium Backup has a 100GB storage cap. For users who frequently exchange photos and videos or participate in many group chats, reaching this limit is only a matter of time. When exceeded, older media may be automatically deleted, potentially causing data loss without warning.
Paid Service Required
Premium Backup is exclusively available to LYP Premium subscribers (monthly fee required). If you cancel for any reason, Premium Backup protection is lost. Even if you re-subscribe later, no backups were performed during the gap.
3. The Reality of LINE's Export Feature
LINE offers a "Send Chat History" feature that exports individual chat rooms as text files. In practice, the limitations are substantial.
- One chat at a time: No bulk export is available. With over 100 chat rooms, you'd need to repeat the process more than 100 times
- Text format only: Images, videos, stickers, and files are completely excluded
- Limited formatting: Plain text (.txt) only, with no sender icons, read receipts, or other metadata
- No re-import: Exported data cannot be imported back into LINE. It's a one-way, read-only operation
For anyone with a significant number of conversations across work and personal life, manual export is not a practical option.
4. Data Lost During OS Migration
Switching between iPhone and Android represents the highest-risk moment for your LINE chat history.
Warning: Without Premium Backup, cross-OS migration restores only the last 14 days of text messages. Everything before that — potentially years of conversations — is permanently lost in an instant.
Premium Backup enables full history migration across platforms, but requires the paid subscription. Countless users only discover this limitation at the moment of switching, when it's already too late to act.
5. The Official Account and System Message Gap
A lesser-known issue involves LINE official account messages and system messages and their backup limitations.
- Official account messages: Conversations with business LINE official accounts may not be backed up, even with Premium Backup
- System messages: Group invitations, member join/leave notifications, and call history may not be preserved
- Time-limited content: Coupons and limited-time messages from official accounts may become inaccessible after expiration
For users who rely on LINE official accounts for business communication, this is a serious concern. Important correspondence and contract-related conversations may not be preserved.
6. Complete Protection with ChatArchive
LINE's official backup alone cannot fully protect your precious chat history. ChatArchive is a local backup tool for Mac users that addresses all of these issues in one solution.
Local Storage — No Capacity Limits
No cloud storage quotas to worry about. Store your entire chat history safely on your Mac. Your available disk space is your only limit — no more stressing over the 100GB cap.
Fast Full-Text Search
Search through past conversations instantly. "When was that appointment?" "What was that quote amount?" — whether for business or personal use, the information you need is always at your fingertips.
Long-Term Archival
Create a permanent archive independent of your LINE account status or device condition. Years from now, even after switching devices multiple times, your Mac backup remains intact and accessible.
Complete Privacy Protection
Your data exists only on your Mac. No uploads to external servers, ever. Zero network communication, zero cloud dependency — your private conversations stay completely private.
