+description: How to backup, restore, and export WebX11 data
+tags: [backup, restore, export, import, persistence]
+category: system
+---
+## Steps
+1. **Backup VFS:**
+   - vfs-export — downloads the entire virtual filesystem as a dated JSON file
+   - backup — creates a full backup including VFS, modules, config (saves to _backups/)
+
+2. **Export/Import personal data:**
+   - my-export — prints all my-set data as formatted JSON
+   - my-import <json> — bulk-import personal data from JSON string
+
+3. **Export/Import modules:**
+   - export-mods — exports module registry as JSON
+   - import-mods <json> — imports modules from JSON backup
+
+4. **Restore:**
+   - restore <json> — restores terminal state from a backup JSON
+   - Session logs are saved to /memory/ automatically on page unload
+
+5. **When to use:**
+   - Before factory-reset: call my-export, vfs-export, export-mods to save data
+   - When switching browsers or devices: export all, then import
+   - User says "backup my data" or "save my files"
