Which storage device is used for backing large commercial servers on multiple tapes?

• A. HDD
• B. Magnetic tape
• C. SD card
• D. SSD

Answer: (B)

Backing up very large server environments on many tapes relies on a storage option that offers huge capacity, low cost per terabyte, and strong longevity for archival copies. Magnetic tape fits this need because modern tape cartridges store substantial data and tape libraries enable automated, scalable backups across many tapes. It’s designed for long-term storage, and tapes can be kept offline or offsite to protect against threats, with a long shelf life when stored properly. The cost per terabyte is typically much lower than hard drives or solid-state drives when you’re dealing with large-scale backups, making it economical for backing up entire servers. Hard drives provide fast access and SSDs are very quick, but their cost per terabyte is higher for the same scale, and they’re less suited to long-term archival and large offsite rotations. SD cards have limited capacity and durability concerns for large backup tasks.
