Automating BRU CLI Backup software on 10.2.6 Server

Hi folks, I'm looking to speak with other folks who have successfully deployed Tolis Group's BRU CLI software on Mac OS X Server 10.2.6. I need some help with automation. Our setup is 1 Xserve,1 XServe RAID, and a 21-tape Exabyte 221L library with one IBM LTO2 drive in it. The Exabyte system is connected via SCSI to the Xserve. Ideally we need to backup information from 6 separate drives/partitions each night in an incremental backup, and then one full backup each month. Right now, I'd settle for just a nightly dump of each partition to its own individual backup process occupying as many tapes as that process would need. I chose to use BRU over Retrospect for several reasons: 1.) No 1TB backup limit 2.) No backup sets and other artificial organization schemes to deal with/fight with 3.) Strength and reliability of a well-known Unix tool that has a very positive rating with many Unix pros I spoken with 4.) Pure speed! This thing is very fast...about 1.8GB/minute! If I manually enter each command to BRU in order, I can get it to work just fine. That is of course cumbersome, so I looked for a better way. The GUI interface for BRU CLI is IMHO buggy and very limited...from what I can see, it offers no library control, so that is not an option for us. Onward to the command line, right? Well... My problem is that automating this software via the command line has been quite a struggle for me. As our firm migrated over to OS X last year, I have been reading everything I can about Unix in order to bridge the gap in my knowledge, but shell scripting is still a major challenge. I have looked at the scripts that Tolis offers on their site, but many of these scripts were written for Linux/Unix or other platforms. Not a one is written for the OS X-only commands in BRU CLI. Also they are setting variables, inserting "if than" statements, and other higher level programming stuff but as of right now I don't need to do any of that. Can anyone offer me some assistance? It would be really helpful if I could see some scripts others are using so that I could pick them apart and get this thing going. I'm committed to making this software work with our systems, but I need a basic working solution to get the job done now until I fully get the hang of this shell scripting stuff. Even a nightly full dump to tape would be great. Thanks for reading... Joe Schram Graphic Systems Manager <><><><><><><><><><><><><><><><><><> Firestar Communications
