Comment 6 for bug 1117709

@Andy: if you only backup the symlinks but not those targets it is pretty normal that you'll get an empty snapshot. This is because rsync ignores links that point outside the copied tree.
You can use 'Copy unsafe links' to fix this. This will only dereference absolute links and links that point outside the copied tree. The 'Copy links' option will dereference all links which is not necessary in your case.
But I would rather include that links target and not use 'Copy links' or 'Copy unsafe links' at all.

@Martin: was this the same for you, too?

To prevent those problems in future I could add a warning if the included file or folder is a link.
