Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My boss asked me to come up with a backup strategy. I was thinking of doing a mksysb for rootvg once a month and some incrementals each week (any comment or suggestions on this strategy are welcome).
I dont know what to do with datavg01 and datavg02. I dont want to use savevg because i'll need like 10 tapes and i only have 1 tape drive with 1 tape slot. Any suggestion? I heard something about Tivoli but i dont even know what that is.
I also have another question...
I have 2 HP/UX machine that needs to be backedup. Is it possible to remotely back the HPUX machines (1 is running hpux10.20 and the other hpux11.0i) using the tape drive (/dev/rmt0) that is connected to my AIX server?
This is the AIX server i need to backup.
root@hostname:/ # lsdev -Cc disk
hdisk0 Available 10-60-00-4,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 10-60-00-5,0 16 Bit LVD SCSI Disk Drive
hdisk4 Available 10-61-00-5,0 Other SCSI Disk Drive
hdisk5 Available 10-61-00-6,0 Other SCSI Disk Drive
hdisk3 Available 10-61-00-3,0 Other SCSI Disk Drive
hdisk2 Available 10-61-00-8,0 Other SCSI Disk Drive
Tivoli is a software division of IBM. They probably have a backup product. You have to look at what you want as they have multiple products that have nothing to do with backups.
Don't use AIX here any more. The team we used to have managing AIX servers ran mksysb about once a month.
You don't mention what tape drive you have or the class of your HP machines or the space used by them. Many HP's came with DAT drives which you could backup to (usually at /dev/rmt/0m). However over 8-10 GB compressed these required you to swap out tapes.
If your HPs have anywhere near the space of the AIX you should explore a commercial backup package. As I said IBM probably has one. The one most used in business is Veritas NetBackup (Veritas is now owned by Symantec.) In my last 4 jobs (including this one) over the last 10 years all of them have used NetBackup. This is designed to allow you to setup one host as your backup master and others as clients. It is also designed to manage tape robots (devices that hold multiple tapes in slots and usually have more than one tape drive).
NetBackup isn't cheap nor are robots but they're a lot cheaper than losing all your data and being down for a day or more due to lack of backup. There are other commercial products like Legato.
Failing all that you can use a tar command line to backup over your lan to your AIX drive. This involves pipes and I forget exactly the syntax since its been awhile. It was something like doing a "tar cv -" on one side and piping it to ssh on the other side then doing dd to the tape or vice-versa. Playing with those options should give you the idea.
We use TSM (Tivoli Storage Manager) here for incremental backups. I wish we could use a NIM server for mksysb. Use a local tape drive (changed daily) for mksysb's and then some SAN storage using rsync to do incremental backups (if you dont intend using TSM).
