HP NetServer AA 6200 Backup/Recovery Guide for HP AA Solutions - Page 1

Backup/Recovery Guide for HP Assured Availability Systems While HP Assured Availability Systems provide very high level of server availability, HP recommends that backups be done at first install, at upgrade times, and periodically to preserve data in the event of disasters. This guide provides important information to help system administrators configure and setup the system for backup. • Backup topologies and their tradeoffs • AA related backup configuration/setup notes • Disaster recovery procedures • Part numbers for ordering backup configurations Backup topologies and tradeoffs There are many backup topologies one might consider for backing up HP AA systems. To help system administrators configure and setup backups HP recommends three topologies. CE boot disk IOP boot disk data disks CE SSDL IL IOP CE SSDL IOP DLT 80r DLT 80r DLT DLT 40r 40r LAN Figure 1: Pure-local backup configuration CE boot disk IOP boot disk data disks The first topology is a pure-local backup configuration (see figure 1). This configuration uses a HP SureStore TapeRack with two DLT80r and two DLT40r tape drives. The two DLT80r tape drives are configured using the Marathon Configuration Utility to be "owned" by the CEs - each DLT80r act as independent tape drives in the CE. Backup software, such as Veritas Backup Exec 7.3 or Computer Associates ArcServe IT 6.61, is installed on the CE 12/08/99 Hewlett-Packard Co. 1
