Sharepoint Server farm Backup errors

Hi All,

I'm having backup issues with Sharepoint 2010 Server farm.

I'm using BE2012 SP1 etc.. Sharepoint 2010 on Windows 2008R2

the error is V-79-57344-5890 - The object was not found, or could not be accessed (Share point backup).

Backup- WebApplication\Content-DB 1 (Server\SP_INTERNET\SharePoint_AdminContent_5cedffe2-ea6b-4ef5-9c2b-5632597f9ef2) SharePoint_AdminContent_5cedffe2-ea6b-4ef5-9c2b-5632597f9ef2 in use - skipped.

All the Databses are there and have the correct access acording to the credential test.

Thanks
