Final answer:
Magnetic tape is common for backup due to its capacity, cost-effectiveness, and reliability. It provides offline backups and is durable.
Step-by-step explanation:
Magnetic tape is common for backup due to its capacity, cost-effectiveness, and reliability. Magnetic tape has a high storage capacity, allowing it to store large amounts of data. It is also cost-effective compared to other storage methods such as hard drives or solid-state drives. In addition, magnetic tape is reliable and can last for a long time without degradation.
One of the reasons magnetic tape is commonly used for backup is its ability to provide offline backups. This means that the backup data is not connected to a network or computer system, making it less susceptible to cyber attacks or data corruption.
Another advantage of magnetic tape is its durability. It can withstand extreme temperatures, humidity, and physical damage, providing a secure and long-lasting storage solution for backup purposes.
