Detailed explanation-1: -Secondary storage provides a lower-cost, higher-capacity storage tier than primary storage, although the stored data might not be as immediately accessible. This tradeoff is worthwhile in some cases, such as when implementing a backup disk appliance or cloud-based backup service.
Detailed explanation-2: -Hard disk drives. Many organizations use hard disks for secondary storage, given the data stored there does not usually have fast recovery requirements.
Detailed explanation-3: -All secondary storage devices which are capable of storing high volume data is referred to secondary memory. It’s slower than primary memory. However, it can save a substantial amount of data, in the range of gigabytes to terabytes. This memory is also called backup storage or mass storage media.
Detailed explanation-4: -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.
