Windows server 2008 R2 64bits Windows Backup Error 2155347997

We had working in Windows 2008 Server Enterprise 64 bits the Windows Server Backup and was working perfect. Then we made the upgrade to Windows 2008 Server Enterprise 64 bits R2 after tht when we want to create a backup it stops giving the error 2155347997. Trying to fix we did this first:

https://blogs.technet.microsoft.com/askcore/2010/06/18/reasons-why-the-error-enumeration-of-the-files-failed-may-occur-during-system-state-backup/

We ran the GetInvalidPathsv2.ps1 and only detect instances of  "The service path contains spaces, the whole path needs to be enclosed using double quotes"

We have other server with Windows 2008 Enterprise NOT R2  and gives identical instances but Windows Server Backup works there.

Now what could be happening after the upgrade to Windows Server R2 why not run there? Before the update in Windows NOT R2 works fine just after the upgrade to R2 began the problem. Also we tried these 2 scripts running from a .bat without luck:
