    I have some difficulties to understand the whole thing.
    The reproduce the problem I ran ntbackup.

    The eventlog showed an errorid=6004 Source=VSS with a text: Sqllib error: Database demo is not simple.

    So I think it should have been possible to track down to problem to the SQL database within a finite time.

    Further tests showed that the error only appears when backing up from a volume on which there a database files of a database in Full Recovery mode. Backing up all other volumes showed no error at all.
    So it is not a problem if SQL Server is installed and running - you simply cannot backup databases in Full Recovery mode using a file backup.
     
    It looks as if database recovery has problems with vss or does not trust vss to backup the database correctly. So I guess the database people are returning the error to vss.

    I do not see any good reason to back up the database when using Full Recovery mode with a file system backup, I would always use the database backup tool.
    So if you separate database files from all other files, you do not have any problem.
