I just purchased a Linkstation Pro LS-XHL, and with it came a copy of Novabackup. After install, the software continually locks up the system its running on, utilizing over 50% of CPU. Furthermore, the backup process does not complete, but instead appears to stop and reset every 15-20 minutes into the backup. I've since uninstalled it. Quite frankly, I'm disappointed that Buffalo would include such poor software with their products - which I've happily used for a while now. I wonder if anyone else has had trouble with Novabackup? Any reliable alternatives that work well with NASNavigator? Thanks for any input.
