Today I backup the SQLServer7.0,it prompt me error:
"Microsoft SQL-DMO(ODBC SQLState:42000)
Backup,CHECKALLOC,bulk copy,SELECT INTO,and file manipulation(such as CREATE FILE) operations on a database must be serialized.
Reissue the statement after the current backup,CHECKALLOC,or file manipulation operation is completed.
Backup or RESTORE OPERATION terminating abnormally."

Pls help me. Thanks with best regards.
