Duplicity 只能在 OS X 上以 root 身份恢复

当我尝试在 OS X 计算机上的 S3 中列出或恢复 duplicity 备份中的文件时，遇到了权限错误：

 Traceback (most recent call last):
  File "/usr/local/bin/duplicity", line 1411, in <module>
    with_tempdir(main)
  File "/usr/local/bin/duplicity", line 1404, in with_tempdir
    fn()

    self.copy_attribs(other)
  File "/Library/Python/2.7/site-packages/duplicity/path.py", line 449, in copy_attribs
    util.maybe_ignore_errors(lambda: os.chown(other.name, self.stat.st_uid, self.stat.st_gid))

    return fn()

    util.maybe_ignore_errors(lambda: os.chown(other.name, self.stat.st_uid, self.stat.st_gid))
OSError: [Errno 1] Operation not permitted: '/Users/dlp/.cache/duplicity/duply_default/duplicity-full-signatures.20130611T011527Z.sigtar.gz'

该文件的权限为 600，我是所有者：

$ ls -alh ~/.cache/duplicity/duply_default/duplicity-full-signatures.20130611T011527Z.sigtar.gz 
-rw-------  1 dlp  staff    11M Jun 11 15:31 /Users/dlp/.cache/duplicity/duply_default/duplicity-full-signatures.20130611T011527Z.sigtar.gz

如果我以 root 身份运行 duplicity，我可以按预期列出文件。这些文件最初是在运行 Debian 7 的 VPS 上备份的。有人知道是什么原因造成的吗？

这应该可以解决你的问题：

$ mkdir -p ~/.cache/tmp
$ duplicity <your options> --tempdir=~/.cache/tmp
