I have created Onenote on sharepoint, shared it across virtual team. All members of the project were actively using this.
To my horror, I realize one of the section was accidentally deleted 😦
By default Onenote will be backed up every week on local machine (retains 2 backups) @C:\Users\%username%\AppData\Local\Microsoft\OneNote\16.0\Backup\.
Different team members had different day latest backup, restored the latest available 🙂
Yes, we lost a day worth of data but glad, was able to recover months worth of data…
