Executive Summary

In this paper, the author will discuss the process of selecting the right mix of disk and tape components to meet the backup capacity, performance, reliability, and security requirements of the environment. Throughout the past 50 years of computing, magnetic tape has been the standard technology for protecting primary disk storage data. Traditionally, IT managers perform weekend full backups and daily incremental backups to recover from lost or corrupted data on their primary storage backup systems. Tapes of these backups are then sent to offsite storage facilities where they become an integral component of the site disaster recovery process.
