What is a good (modern) alternative to > DDS-4 working on FreeBSD? For our multi-TB systems, we do disk-based backups using dar ... to another multi-TB system. :) We use a custom shell script to handle creating full and incremental backups and to rotate through multiple directories to keep a couple backups around. All via gigabit ethernet and NFS. And once a week we copy a full backup offsite via SSH tunnels to another multi-TB system via a gigabit fibre link. We're using RAID5 with hot-spares on 3Ware 9550SX controllers. -- Freddie Cash, LPIC-2 CCNT CCLP Network Support Technician School District 73 (250) 377-HELP [377-4357] fjwcash+freebsd@gmail.com
