You skipped Step 1. Please define your RTO and RPO, then you can start to evaluate your options. If your RPO is 24 hours then Simple Recovery Model with nightly FULL backups could be enough. If your RTO is 30 minutes then FULL recovery model with Mirroring or Log Shipping will probably make more sense.

RTO > Recovery Time Objective
: the duration of time and a service level within which a business process must be restored after a disaster (or disruption) in order to avoid unacceptable consequences associated with a break in business continuity, i.e. how long can the system be unavailable while databases are being recovered.
RPO > Recovery Point Objective
: the maximum tolerable period in which data might be lost from an IT service due to a major incident, i.e. how many seconds worth of data can the business tolerate losing.
Business Continuity implies the resumption of normal operations, however inevitably it means the prospect of the business itself surviving the disaster. You can Bing or Google to dig up some current stats about how many business completely go under after they lose a non-trivial amount of their proprietary business data.
