Sharepoint 2010 and Foundation 2010 with same SQL in one backup job does not work
I'm backing up a Sharepoint 2010 Farm with databases on a MS SQL 2008 R2 SP1 CU2 for some time without issues.
Now I tried to add a Sharepoint Foundation 2010 Farm with databases on the same SQL Server to that backup job.
After I added it, the Job failed while backing up the Sharepoint databases (error 0xE000FE1F: The device cannot be found).
In the same job it backup the SPF databases on the same server without problems.
Now I removed both farms from the job, added only the SP farm. It worked.
Now I added the SPF Farm again and now the databases from the SPF farm failed with the same error like the SP farm databases before, but now the SP Farm databases succeded in this job.
Is this a known issue?

All databases are on the one single SQL Server
