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'm just after some advice with using NFS or SCP for a remote database backup using a cron job. I have a script running on my database server that backs up
the database and copies it to another server. From the other server I
then tar the backup to a tape drive connected to it. My first option is
to use an empty dsa key so I can scp without a password, Within the
script I can also ssh into the other server and run the tar command.
The second option is to have an NFS share on the other server and copy
the backup to that directory. However this means that I can't remotely
run a tar command, and I would need a cron job on both servers.
I would like to run everything in one script, but would it be better to use
NFS? Internal security isn't a big issue, and I can't connect the tape
drive directly to the database server.
