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.

I am fairly new to the UNIX world in general. I have a server machine running Red Hat 8.0 Professional. Several weeks ago, I had a catastrophic problem, and had to rebuild the entire machine. At the time, I had a SUN DLT 4000 tape backup unit hooked up to it via an Adaptec 2940 SCSI card. Prior to that failure, I had never taken the time to LEARN how to backup the system, and therefore, I did not have a backup. My server is rebuilt now, and my number 1 priority is to get it backed up on a weekly basis. I want to back up EVERYTHING on the system onto 1 tape(40GB capacity tapes). However, like I said, I don't know anything about backing up right now, but I need to get it working. A friend of mine told me that there is a simple "tar" command I can use that will backup every single thing onto the tape. Can someone please explain to me what this might be? I am a newbie to this, and I intend on truly learning about backups soon, but I need to get it working before I learn. What I want to do is set the server to backup automatically, every Sunday night at midnight. I want it to do a full backup, and rewind to the beginning of the tape when it is done, that way, the next week's backup will overwrite it. Can anyone explain this to me step-by-step. You'd be a lifesaver!!! Thanks a million!
