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 


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.
