  1. Older 3rd party RBS settings/binaries - even though they were removed -  may still be conflicting with the current web app and content DB and causing unexpected results.
  2. When one front end web server completes the RBS configuration, internally SharePoint API updates a persistent farm object behind the scenes. The same persistent object is shared by all front end web servers. Once one of the front end web servers RBS configuration is completed, Commvault attempts to install RBS on remaining front end webservers. As the first front end server is still busy updating persistent objects, this causes an update conflict error.
  3. User Provided a wrong BLOB location which doesn’t exist.
  4. No permissions to access the BLOB location.
  5. Timer service isn’t started on the other WFE servers.
  6. Configured SharePoint timer service in the Farm on multiple WFE’s with different accounts .


  1. Completely remove the 3rd party RBS provider and reinstall Commvault’s RBS provider.
  2. Install Sevice Pack 9 which includes updates 15646 to correct other unexpected behaviour.
