Restore BCK problem

[Jose Antonio_5]

Hi all,
I need your help¡¡¡¡

I have been making an HPSIM database backup with those staments (osql):
-------------------------
@command = "BACKUP LOG Insight_v50_0_92441910 TO DISK = 'C:\compaq\osql\BACKUP\BCK_BBDD\INSIGHT.log_bak'",
@command = "BACKUP DATABASE Insight_v50_0_92441910 TO DISK = 'C:\compaq\osql\BACKUP\BCK_BBDD\INSIGHT.dat_bak'"
-------------------------

More later, I had a problem and I reinstalled HPSIM. When I try to restore the backup with this stament I obtain:
-------------------------
@command = "BACKUP DATABASE Insight_v50_0_11111111 TO DISK = 'C:\compaq\osql\BACKUP\BCK_BBDD\INSIGHT.dat_bak' with norecovery"
-------------------------

-------------------------
