You are using GFI Managed Online Backup (MOB) and it reports “No Volumes Selected” when trying to backup SharePoint.
All backup programs use VSS writers in order to backup the different programs on a PC or Server.
If a server hosting Sharepoint cannot backup Sharepoint shares with the error “No Volumes Selected” then the most likely cause is the VSS Writer is no longer registered on the server.
To confirm this, do the following:
- Open a command prompt with administrator privileges.
- Run the following command: VSSAdmin List Writers.
- If the Sharepoint VSS Writer is missing, go to the following link to resolve the issue: http://www.puryear-it.com/blog/2014/06/09/how-to-register/
