Why would one get this error when one is already doing a full backup ???
Is it a bug in 8.0 ?
Backup is being done against a 7.0 SQLserver

Backup Type: DATABASE - Back Up Entire Database
Backup started on 8/30/00 at 10:23:45 PM.

An error occurred on a query to filegroup master..PRIMARY.
^ ^ ^ ^ ^
SQL Server returned the following error message:

You can only perform a full backup of the master database. Use BACKUP
DATABASE to back up the entire master database.

Unable to open the item master?PRIMARY - skipped.
