BackInTime不能删除快照吗？

Question

由于电源故障，我在快照期间关闭了外部驱动器电源，现在无法删除new_snapshot文件夹。

起初，我认为我可以只给程序sudo许可，但这似乎行不通。

这就是在使用GUI并尝试拍摄新快照时发生的情况：

从终端上看，这是什么样子：

sarah@ConvergentRefuge:~$ backintime backup

我使用的是Kubuntu 18.04.01，我的备份是加密的。

我也有过同样的问题。原因是Backintime在savint之后将所有文件设置为只读。因此，常规用户不能再删除快照目录了。您可以手动删除目录“新快照”作为根目录。如果是在NAS上，您应该登录NAS并删除als根目录。但是要小心。;-)

顺便说一句:在我的系统中，如果backintime尝试删除旧快照，也会发生同样的情况。它无法工作，因为auf缺少权限。我原以为BIT能处理这个问题，但至少在QNAP NAS上，它不起作用。有人知道该怎么做吗？
