Which of the following is typically used for large data backups of servers?

1. External SSD

2. DLT Tape

3. USB Flash Drive

4. Optical Disk

The correct answer is: DLT Tape

The selection of DLT (Digital Linear Tape) Tape as the appropriate choice for large data backups of servers stems from its design and capacity. Tape storage, such as DLT, is specifically engineered for high-volume data storage, making it ideal for backing up servers that often have substantial amounts of data. DLT tape systems are known for their high storage capacity, durability, and cost-effectiveness per gigabyte when compared to other storage methods. They can store several terabytes of data on a single tape, which allows organizations to efficiently backup extensive server data without needing multiple replacement media. Additionally, tape drives have a long lifespan and are less susceptible to damage from environmental factors than many electronic storage media. In contrast, external SSDs and USB flash drives, while useful for smaller data transfers or temporary backups, typically have limited storage capacities and higher costs per gigabyte, which makes them less ideal for large-scale server backups. Optical disks also do not offer the storage capacity or reliability desired for enterprise-level data backup solutions and are often slower in terms of data access and writing speeds compared to tape technology. Therefore, DLT tape systems are the most suitable option for backing up large volumes of data on servers.
