Which statement best describes trade-offs among backup targets such as D2D2T, NAS, SAN, and cloud?

Which statement best describes trade-offs among backup targets such as D2D2T, NAS, SAN, and cloud?

• A. All backup targets offer the same speed and cost, so selection doesn't matter.
• B. D2D2T is always faster than cloud for DR.
• C. NAS and SAN always provide offsite DR with no latency.
• D. Cloud provides offsite DR but may incur egress costs and latency.

Answer: (D)

Backup targets are all about trade-offs in speed, cost, and where the data resides for recovery. Using cloud for offsite disaster recovery provides protection by keeping copies far from the primary site, which helps guard against local disasters. But pulling large amounts of data from the cloud can incur egress charges, and the data must travel over the network, introducing latency that can affect recovery time objectives. Local targets like D2D2T, NAS, and SAN typically offer faster restore times and lower ongoing costs for on-site operations, yet they don’t automatically provide offsite protection unless you add a separate replication path, which adds complexity and expense. So, cloud uniquely offers offsite DR with the real costs that come with data transfer and network latency, making that statement the best description of the trade-offs.
