how do you want the backup to work? the free backup solutions, like ntbackup which is included in windows, can be suitable for some of the needs

hope u all can help me...

thanks

what do you want to back up exactly?

The backup serevr will be required to take over operation and prevent the system down should the main server failed at any reason. It's database will be syncronized all the time with the main server, without any lost of data should the primary server fail at anytime.

Hope you understand.

ok, I do now.
what you're looking for is a failover cluster. you can either set one up using microsoft cluster services, or buy some third party software like XOsoft Wansync, DoubleTake, Neverfail-R2 etc.

MS clustering is free, if you have windows 2003 enterprise edition. but you need a shared SAS or SCSI (or even SAN) storage to host the quorum.
that can be achieved by buying a DAS/iSCSI or SAN box, or by setting up a third server using software iSCSI target services

thanks for the info ... i'll try to look up for that
