Restoring Exchange 2003 DB's via Backup Exec always need to be repaired

Hi,

 

We backup our Exchaneg DB's every night, however I manage to restore all the DB's fine but can never mount them until I use the Exchange tool to repair, so I am wondering I cam backup correctly?

 

I use:

 

Backup method:

 

Full - Database & Logs (flush committed logs)

Perfom consistency check

Continue with backup if check fails

 

 

To restore:

 

I untick the commit after restore and mount DB's after restore

Purge existing data and restore only the databases and transaction logs from the backup sets

Thanks
