Time Machine backup over VPN? (reprise)
I found this thread (https://discussions.apple.com/thread/2662530?start=0&tstart=0), which leads me to believe it is possible. My server is Lion (equipment too old to update to Mountain Lion), and the L2TP VPN is functioning perfectly. I go to Finder, do Go / Connect to Server and connect to the backup drive. I am able to see the contents. However, when I go to Time Machine Preferences, then try to select backup disk, it doesn't show up in the dialog.
Otherwise everything else on my VPN is functioning perfectly.
Any clues where to look or what to try?
Thanks in advance.
