Server Optimization

Currently our vault and associated file servers are hosted off site.  This coupled with firewalls and other filtering software has degraded our performance dramatically.  I am requesting to move our server back inside the building, but I still need to account for disaster recovery.  What are other people doing to back up off site?  Would it be better to backup at set intervals or to replicate the vault to an off site server.  Performance is important but safety is equally important.  Suggestions?

Thanks

Mark
