continuous backup of "deltas"?

Can Backup and Recover 2012 be used to back up all changed files every 5 minutes (for example)? And if I've made a little change to a very large file that's already been backed up, will the whole file be backed up the next time, or just the part of the file that changed? (These are pre-sales questions that will help me decide if the program would be a good choice for me.) Thank you very much for your help. -Alan
