There are several features for software backup processing that makes it more efficient.
Volumes: Voluming allows data to compress and split, which can be stored in separate parts and removable media such as Compact disks (CDs), floppy disks and magnetic tapes.
Encryption: It provides some cryptography features using backup software to protect the data and prevent from data theft.
To provide a structure to the stored data, a data repository model is used. There are different types of data storage devices that are useful for making backups and these devices can also be arranged in different ways to provide geographic redundancy, data security and portability.
