Hi, I want few clarifications with respect to Exchange backup. I have Exchange 2003 SP1 running on Windows 2003, Hardware Dell 2850 with Mirroring for OS and RAID 5 for exchange database, LTO (10 Slot autoloader) tape drive is connected to backup server and backup is taken over LAN, Arc server backup software (11.0) I went trough the Disaster recovery planning and operations guide from MS, however I am not able to understand how exactly ?restore the server? method works!! Taking full system backup is fine, but what is the exact procedure to restore in case of a system crash. It seems obvious that windows 2003 OS & backup agent needs to be freshly installed (in case of a failure) and then only I can restore from backup. But if I do so OS will not allow overwriting of system files! Is ?restore the server? only for Exchange 2003 application???? I am not clear because document says ?Windows 2003 full computer backup set? what exactly this means?? Can some one please explain me how ?Restore the server? works. Also please let me know the best backup policy for a 50 Gb database and a SLA of 2 hour down time in case of major failure. Regards Praveen R --------------------------------- Discover Yahoo!
