Hm, rebooted, and the VSS services is started from bootup. Jungledisk is not running a backup.
I'm running Windows XP, SP3. As mentioned earlier, Ghost backups go to an external (USB) drive.
Running Jungledisk (and even starting a backup using Jungledisk) does not seem to cause any activity at all in the windows application log. And, looking back over the past few days' log (with Jungeldisk running a backup each night), I see no "snapshots" going off, or other Symsnap-related behavior showing up in the application log (if you mean the one in Control Panel/Event Viewer).
