This article was previously published under Q167331
BUG #: 16349
SYMPTOMS
When backing up a database to a tape drive, error 3201 may occur:
Msg 3201, Level 16, State 1
Can't open dump device '\\.\tape0', device error or device off line.
Please consult the SQL Server error log for more details.
Often, there will not be an accompanying error message in the errorlog,
even though the message indicates that there should be one. This error may
be caused if the tape block size of the tape drive is larger than the
backup buffer size in SQL Server's sp_configure.
WORKAROUND
To work around this problem, use sp_configure to modify backup buffer size
to a value that is equal to or greater than the tape drive's block size.
STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server
version 6.5. This problem has been corrected in U.S. Service Pack 3 for
Microsoft SQL Server version 6.5. For more information, contact your
primary support provider.
