DejaVu备份不适用于google驱动器

Question

我最近尝试切换我上传备份到的google驱动器，但是现在备份工具(Deja)已经不起作用了。当我尝试做备份时，它会扫描，然后用

Giving up after 5 attempts. timeout: The read operation timed out

我将如何进行故障排除和调试？我已经尝试删除我所有的在线帐户，并添加新的谷歌帐户，我想使用。( google和ubuntu )我也尝试过重新安装duplicity和deja-dup，并重新设置deja的所有设置。到目前为止，什么都没有工作，当我从终端运行deja-dup时，没有任何错误消息。

编辑1：

正如古洛德建议的那样，我用DEJA_DUP_DEBUG集合运行deja。下面是日志输出：

.... // at this point the error would repeat 4 more times and deja-dup would give up.

这似乎表明deja-dup能够访问我的驱动器，但有些读op不工作？我检查了我的驱动器，文件duplicity-full-signatures.20200821T014731Z.sigtar.gz似乎不存在。也许deja-dup试图读它，但它不能，因为它不存在？我该怎么解决这个问题？

Answer 1

这并不是对你问题的真正答案，而是一种可能解决你问题的替代方案--谷歌的驱动器挂载，看起来和任何其他的挂载或硬盘差不多。我使用deja-up来备份文件，这样就没有任何问题了。

过去，我在Ubuntu中使用Google驱动器时遇到了许多问题，并且支持它的内置功能。它可以做一些基本的事情，但仅此而已。所以我从这里开始使用google-drive-ocamlfuse：https://github.com/astrada/google-drive-ocamlfuse

所有细节都在github产品页面上，但我认为这就是我所做的：

安装包google-驱动器-ocaml引信：

sudo add-apt-repository ppa:alessandro-strada/ppa
sudo apt-get update
sudo apt-get install google-drive-ocamlfuse

Web浏览器登录以获取访问令牌：

google-drive-ocamlfuse -label YOUR_GOOGLE_ACCOUNT_HERE

创建一个安装点：

mkdir /home/wherever/Documents/mygoogledrive

山：

google-drive-ocamlfuse -label mygoogledrive /home/wherever/Documents/mygoogledrive

如果fusermount -u /home/wherever/Documents/mygoogledrive不能工作，则使用-u卸载或用于延迟卸载的fusermount -uz /home/wherever/Documents/mygoogledrive。

就我个人而言，我只有一个启动脚本运行卸载和挂载命令，然后如果我遇到任何问题，我只是重新运行脚本。

Answer 2

我也遇到了同样的问题。第一次，它最终消失了，可能是因为可变的Google响应时间。当手动复制duplicity想要在缓存中下载的文件时，这需要稍微超过30秒，我认为这是pydrive和/或用于下载文件的底层库httplib2和http中使用的默认超时值。这个延迟是响应时间，因为一旦开始~ 50 MB的文件传输，就需要大约1秒的时间来完成。

我可以通过在duplicity's pydrivebackend.py (见GitLab)中硬编码60秒超时来暂时解决这个错误，在它实例化GoogleAuth()的三个地方，即GoogleAuth(http_timeout=60)。

这不是一个永久的解决办法。如果返回，我想我们应该研究一种在deja-dup x duplicity x pydrive中指定更高的HTTP/Google请求超时值的方法。

我希望这能帮上忙，如果你有什么问题请告诉我。
