Thanks for this article - answers a question that I''''ve just been asked by my client - how do they restore just a file that they accidently modified two months ago and have only just noticed. The answer out of the box is that they can''''t. When I managed an onsite system, we had DPM keeping backups of our file system for about six months. Never managed SharePoint on premises so don''''t know whether the DPM SharePoint option could do the same. Do you know if there are 3rd party options to take a separate backup of SharePoint online?
