Cannot create system state backup with DPM, error code: 0x80990ED0

Today I experienced a problem when it was not possible to create a system state backup through System Center Data Protection Manager 2012 R2 on a Windows Server 2012.

The error code was:
DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 546, WSB Error Code:  0x32F4570). (ID 30229 Details: Internal error code: 0x80990ED0)

This usually means that Windows Server Backup feature is not installed on the server. But that was not the case. First, I restarted the server, it didn't help. Second, I reinstalled Windows Server Backup, but that didn't help either.
After some time of googling with no results, I discover that Windows Server Backup could not successfully open on the server, it hung up. Then I also noticed that Disk Management was not opening correctly, it didn't show disks.
So this was the root cause of the problem - some disks were not correctly added through FC network and this caused errors in Disk Management and Windows Server Backup. After resolving issue with disks, backups were created successfully.

Bottom line: error code 0x80990ED0 means that Windows Server Backup is not installed or not functioning correctly.
