I use Git for software version control. Git stores information in a hidden folder .git within a directory. It appears that Duplicati is not backing up this folder. When I look at my configuration file (with the Show Hidden Files checked), I can see that the .git folders are selected for backup. However, when I try to restore, that folder is not listed and is not restored.
This is serious problem because if I have to restore a source code directory, I will lose all revision history and all software branches other than the currently selected one.
