Error in in sysft_Name while restoring database
I think you need a "\" at the end of the path.

RESTORE DATABASE [new] FROM DISK = N'E:\a\L11.bak' WITH FILE = 1, MOVE N'itest' TO N'E:\a\3.mdf', MOVE N'itest_log' TO N'E:\a\4.ldf', MOVE N'sysft_test' TO N'E:\a\', NORECOVERY, NOUNLOAD, REPLACE, STATS = 10 
GO
