Hello Experts,

My question is somewhat off topic, I hope that is okay. I am trying to
figure out how to setup site redundancy for online highschool and university
setup, a backup site for our primary location so in case of power/equipment
failure or ISP issues, the users are not effected by the down time.

   1. In case of failure at the main site, the switch over should be
   seamless to the end user. I believe this is possible with DNS load
   balancing, any recommendations? Off site dns load balancer?
   2. SQL databases should sync hourly or at least once a day for latest
   data at the backup site.What software would do this?
   3. What type of equipment is required on each site to accomplish this
   setup? Cisco's CSS of any use here?
   4. Do I need to get a dedicated site to site VPN?

Any other suggestion or ideas would be greatly appreciated.

Thank you,

Haroon
