Storage and Backup Strategies/Services

This document outlines the storage and backup strategies employed by the Fred Hall Division of Engineering Computing Services at Michigan State University. It provides insights into the importance of data backup for disaster recovery, both from external and internal events. The university has approximately 1.5 terabytes of data, utilizing a Network Appliance and RAID 5 SCSI arrays for optimal storage. The backup systems in place include two Sun servers with DLT cartridge libraries and the Solstice Networker backup software, ensuring nightly incremental backups and monthly full backups, enhancing data security and user confidence.
