I'm researching a sever clustering architecture as a redundancy and backup solution for a client, and something that isn't made clear is whether or not i can use server clustering to replace a file server with backup solution. Forgive my Elementary understanding of server clustering but supposing:

1. 2 Sites (NJ, CA)
   
2. Identical Servers at each site setup as a Remote Site Cluster nodes with Windows Enterprise server 2008 r2
   
3. Services: File, Terminal, AD, and maybe DNS
   

Will the following will be true: Files (including data drives) will be synced between the two servers eliminating the need for third party backup/mirroring software to sync/backup files.

Also supposing i use roaming profiles w/ folder redirection; How will client computer in the WAN access their data through the cluster (i.e. will they automatically choose the best route)
