Assume that you have a file that contains lots of extents (such as Microsoft Outlook .PST files) on a server that runs Windows Server 2012 R2 or Windows Server 2012. When you try to back up the server by using a backup application that uses the native backup APIs, the application process crashes, and the backup operation fails. For example, the Data Protection Manager Replication Agent process (DPMRA.exe) crashes during the backup.
