Why each option
Meeting on-site and off-site backup requirements demands one backup destination within the local facility and a separate destination at a physically remote location.
Backing up to secondary disks and then cross-backing to the network keeps both copies within the same facility, failing to provide a true off-site backup.
Backing up to a NAS at the MDF and then to another NAS on-premises keeps both copies within the same building, which does not fulfill the off-site backup requirement.
Backing up to a SAN volume at headquarters and to another on-premises location lacks true geographic redundancy, and a weekly off-site interval introduces excessive recovery point exposure.
Continuous replication to the NAS drive in the server room satisfies the on-site backup requirement by maintaining a constantly updated local copy for fast recovery, while the nightly backup to a remote location satisfies the off-site requirement. This combination provides both immediate local recovery capability and geographic redundancy against site-level disasters.
