They are junction points. Windows uses a multi-root directory hierarchy, where C:\, D:\, etc. are the roots, as opposed to the *nix single root directory hierarchy where / is the only root. Any directory under one of the roots that has a NTFS filesystem mounted may be the mountpoint for a different filesystem. Windows calls these "junction points". Windows implements directory symlinks as junction points, the only difference being that rather than a completely different filesystem being mounted at the junction point, a subsection (directory) of the same filesystem is re-mounted at the junction point. Therefore, Bacula sees these junction points as a different filesystem, (as it should). For example, what is now c:/Users/johnm/Documents on Vista/7 used to be c:/Documents and Settings/johnm/My Documents on XP. There were enough compatibility problems with old 3rd party software hard coding the "My Documents" directory name that, for backward compatibility reasons, Microsoft put in a symlink (junction point) named "c:/Users/johnm/My Documents" that points to the Vista/7 equivalent "c:/Users/johnm/Documents". You should not be concerned. Either ignore the messages or else exclude those directory names in the FileSet used by Vista/7 clients. > On a Windows XP machine, we also get some of these, but fewer: > > tomasv200-fd JobId 2539: > c:/WINDOWS/assembly/GAC_32/System.EnterpriseServices/2.0.0.0__b03f5f7f11d50a3a > is a different filesystem.
