我正在使用 duply / Duplicity 来备份我的 /var/www 目录，但该任务不起作用。它总是失败并显示以下错误消息：
Copying duplicity-new-signatures.20150827T090338Z.to.20150828T000005Z.sigtar.gz to local cache.

一方面它说“完成状态OK”，另一方面它说“错误2”。这有点令人困惑。
好的，这可能表示备份成功，但关于“错误 2”消息，我最好修复它，我将来会收到“错误 0”。
有一些 cronjobs，每 7 分钟在系统上运行一次“svn update”。
有人有想法吗？我期待着您的回答。谢谢！
