[Bug] 媒体备份并没有遵循指定的压缩格式
Describe the bug 如题，不管选择什么最后都生成的 tar，检查了日志 tar 命令前后没有调用过 lz4 或 zstd，这是否符合预期？

不过，能否将此作为一个 feature request 呢？

可以倒是可以，但媒体备份经过多次测试用zstd并没有很好的效果，所以在一段时间后默认改为了tar，我和脚本作者都认为再压缩一遍意义不大
图片视频都比较固实，字典效果不大 但用在手动指派一些混合的数据目录效果就会很好
另外在比较同类软件 MuntashirAkon/AppManager 时发现还缺少两个价值比较大的功能，不知道是否用新开一个帖？
- 哈希校验 确保备份文件传输后的完整性
- 权限备份 能大幅提升玩机幸福感（确信

了解了，下个版本加上吧

请不吝赐教
- 哈希校验 确保备份文件传输后的完整性
- 权限备份 能大幅提升玩机幸福感（确信
这两个后面也会跟进
喔，价值比较大的功能其实就是指下面那两个，哈希校验和权限备份，想问还用再开一帖 Feature Request 嘛 最后，感谢您对开源的热情 : )
