(ii) Archival-The saving of old or unused files onto magnetic tape or other offline mass storage media for the purpose of releasing on-line storage room.

(iii) Restore-The process of bringing offline storage data back from the offline media and putting it on an online storage system.

(iv) Storage replication-Storage replication is a service in which stored or archived data is duplicated in real time over a storage area network. Storage replication service provides an extra measure of redundancy that can be invaluable if the main storage backup system fails. Storage replication may be done in the same storage array, different storage arrayfs in the same location or a storage array in a remote location. Immediate access to the replicated dataminimizes downtime and its associated costs. The service, if properly implemented,can streamline disaster recovery processes by generating duplicate copies of allbacked-up files on a continuous basis. It can also speed up and simplify recovery from a natural or human-caused disaster such as a fire, flood,burricane, virus, or worm.
