What is a common cloud-based backup/DR option for on-prem networks, and a typical trade-off?

• A. Cloud storage with cross-region replication that offers offsite resilience but can introduce latency and egress costs
• B. Cloud DR eliminates all latency and cost concerns
• C. Cloud backups replace the need for on-prem backups entirely
• D. Cloud DR is always cheaper and easier

Answer: (A)

Cloud-based backup and disaster recovery for on-prem networks usually relies on storing data in the cloud with replication across regions to keep a copy offsite. That offsite resilience is the main advantage, giving protection even if the on-prem site is damaged. The trade-off is that this approach can add latency for backups and restores due to network transfer, and it incurs egress and cross-region data transfer costs. Other statements imply that cloud DR eliminates latency and costs, replaces on-prem backups entirely, or is always cheaper and easier; those ideas don’t align with real-world trade-offs, where you gain offsite protection but must manage network performance and ongoing transfer charges.
