Usage guidelines for storing research data in Microsoft Teams
Each team within Microsoft Teams is allocated 5TB of storage, suitable for all data classifications. Microsoft provide a 30 day recovery facility for files stored within Teams, see below for details on browsing the history.
This shared space is useable by all team members so any one could delete/damage files accidentally and if team members have folder synchronisation setup onto their desktop/laptop computer then any malware on that host may effect your Teams hosted files.
You should also be aware that should all members of the Team leave the University, then all data held in that Team will be irretrievably deleted after 60 days.
The Teams bulk recovery system is not fine grained - it can only restore the state of the whole Team storage to a particular point in time.
If you find you have damaged a Microsoft Office file then you can use the application to view the version history of the file to recover earlier versions.
For other file types, if you navigate to the folder containing your damaged/lost file in Teams and then use the 'Open in SharePoint' toolbar option (it may be hidden in the '...' menu).
If your file has been deleted then use the 'Recycle bin' menu item on the left to view the deleted files.
If your file has been damaged, then click on the '...' in the line for that particular file and use the 'Version history' menu option to browse the available versions of the file.
