Subject: [PATCH 1/2] fix(backup): use relative paths when creating tar.gz
 archives on macOS/Linux

- Fixed error "paths in archives must be relative" during compressed backup
- Updated compress_tar_gz() to use append_path_with_name() with file_name()
- Ensured compatibility with macOS and Linux tar implementations
- Verified consistent behavior across all platforms
