我正在尝试从旧的重复备份中提取备份(由 ubuntu gui 完成,我相信它是 deja-dup)。
我从一个垂死的硬盘上复制了所有我能做的东西。我有
- 很多
difftar.gz
文件——一些 2014 年和一些 2016 年。 - 2014 年的一个
.manifest
文件。 - 没有
sigtar.gz
文件
备份未加密 - 我解压缩了一个difftar.gz
文件并在十六进制编辑器中检查它,我可以看到很多纯文本。
运行一些命令:

假设我无法从原始硬盘驱动器中提取更多文件,我是否可以选择提取文件?
我对提取照片最感兴趣——如果我可以提取一个没有名称或文件元数据的照片文件,那么这将是一个胜利。
