We are building a mission critical application in OneNote 2013 and I want to develop a backup methodology that lets me restore from a few days back in case we discover a corruption. I changed the option 'Number of backup copies to keep' to 10, then have it set to back up every day. Under my backup folder path it created subfolders '15.0/Backup' which then contains folder for each of my notebooks. I can see recent additions to some of the folders so the backup does seem to be saving changes daily, but it is not separating them into separate folders for each day. Is there a way to set up OneNote backup so that each day it creates a separate backup such that I could go back 3 days and get the state of all notebooks without changes made more recently than 3 days ago? Thanks!
