Yes, if Live Protect is set for some files which are updated regularly, then our product performs differential backup and updates the changes of files each time the file is updated and saved. Our product may work in the background when running scheduled backups and when a back up is manually invoked.

Live Protect is a special Viper feature.  It allows you to pick files that you wanted backed up in Real Time. So if you have an important Excel document that you update frequently, it will automatically back it up to the Viper Cloud, every time you save it.
