### Backup Issues
**Problem**: Backup fails with encryption error
**Solution**: Ensure you have proper permissions and sufficient disk space
**Problem**: Can't restore from backup
**Solution**: Verify backup integrity and check version compatibility
### Performance Issues
**Problem**: Slow analysis with large projects
**Solution**:
- Exclude node_modules and other large directories
- Use `.i18nignore` to skip files
- Increase Node.js memory limit: `NODE_OPTIONS=--max-old-space-size=4096 i18ntk analyze`
## π Troubleshooting
### Enable Debug Mode
```bash
# Set debug environment variable
export I18N_DEBUG=true
# Or use the debug flag
i18ntk --debug <command>
Logs are stored in .i18ntk/logs/ by default. Check the latest log for detailed error information.
export I18N_DEBUG=true
i18ntk --debug
### View Logs
Logs are stored in `.i18ntk/logs/` by default. Check the latest log for detailed error information.
### Get Help
```bash
# Show help for all commands
i18ntk --help
# Get help for a specific command
i18ntk <command> --help
# Check version
i18ntk --version
