When selecting backup media, which factors are considered?

• A. Size, Compatibility, and Temperature
• B. Speed, Cost, and Power consumption
• C. Capability, Reliability, Extensibility, Speed, Cost
• D. Brand reputation only

Answer: (C)

The main idea is weighing backup media by how much you can store, how reliable the media is, how well you can grow the solution, how fast you can back up and restore, and what it will cost over time. Capability covers capacity and features that affect backup and restore, such as how much data you can hold, compatibility with your backup software, and options like encryption, compression, and deduplication that influence effectiveness and recovery. Reliability focuses on data integrity and durability—low failure rates, strong error detection and correction, solid warranties, and a predictable media lifespan—so you can trust restorations when needed. Extensibility is about future growth: you want scalable capacity, easy addition of media, and smooth compatibility with newer hardware or automation so the solution isn’t stranded as data grows. Speed matters because it directly impacts how long backups run and how quickly you can recover, influencing your backup window and RTOs. Cost wraps it all together, including initial purchase price, ongoing media costs, maintenance, energy use, and replacement cycles; a balance is needed so the solution remains affordable throughout its life. In practice, you evaluate options across these dimensions against your data volumes, retention policies, recovery objectives, and budget, and pick the one that best fits those needs. Choices emphasizing environmental factors like temperature, or focusing only on a single aspect or branding, don’t address the full set of considerations necessary for a robust backup strategy.
