Comment 1 for bug 1269991

a text file with last snapshot name is not very helpful. The 'last_snapshot' symlink was a wish from guys who want to access the last snapshot over network share.
I added an exception handler to os.symlink so it will fail silently.

If your destination drive (e.g. CIFS) doesn't support symlinks you can enable 'Copy links (dereference symbolic links)' in Options. This will copy those links targets instead of the link itself.
