Detailed explanation-1: -Secondary storage is non-volatile and able to keep data as long term storage. They are used for various purposes such as backup data used for future restores or disaster recovery, long-term archiving of data that is not frequently accessed, and storage of non-critical data in lower-performing, less expensive drives.
Detailed explanation-2: -Secondary storage is necessary because memory, or primary storage, loses its data when a computer is turned off whereas secondary storage does not. Therefore, it is commonly known as non-volatile storage. The data on it stays there until it is deleted or overwritten by the user.
Detailed explanation-3: -Backup copies allow data to be restored from an earlier point in time to help the business recover from an unplanned event. Storing the copy of the data on separate medium is critical to protect against primary data loss or corruption.
