GitHub Backup Instructions

1. Create GitHub Personal Access Token with repo permission, recommend no expiration
2. Configure token, owner, repo in config file
3. Enable github.enabled: true
4. Private repo auto-created if not exists (requires auto-create-repo: true)
5. Empty repo auto-initialized (README.md written), otherwise Release creation fails
6. Backup files uploaded as Release Assets, single file limit 2GB
7. GitHub scheduled backup shares interval-minutes with local backup
8. All network operations (upload/download) execute asynchronously, non-blocking main thread
9. Manual /backup github-upload will auto-clean local old backups (subject to max-backups limit)

Dual-Mode Scheduled Backup

The plugin supports two independent trigger modes that can be enabled simultaneously:

1. Interval Mode (backup.auto-backup: true + backup.interval-minutes: 60)

• Execute backup every N minutes
• Suitable for high-frequency backup scenarios

2. Time-Based Mode (backup.schedule.enabled: true)

• Execute backup at specific times in a specified timezone
• Supports custom timezone (e.g. Asia/Shanghai, America/New_York, Europe/London)
• Supports 24-hour format (HH:mm, e.g. 00:00, 12:00, 18:30)
• Supports 12-hour format (hh:mm a, e.g. 12:00 AM, 06:00 PM)
• Multiple trigger times configurable

Both modes can be enabled together without conflict. Example: interval mode backs up every hour, time-based mode adds extra backups at 00:00 and 12:00 daily.
