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.

Hi, I use Backup Exec and Dell's PV32T library, they saved my life a couple of times. Formerly i used DDS4 tapes units, they worked fine but you have to chage the media continuously, well it depends of the amount of data you are going to back up. Cheers.
I usually dont backup and when i Do , i write cds mostly 2-3cds of same data
Just recently i had to fomrat entire drive so i did same .......... made 2 copies of all data I needed and bang !
I usually prefer 3 copies but made 2 coz of time constraints ...
thats coz if one cd gets broke, i have other or sometimes just a certain file cant b copied from a cd
At home I use a 500GB external hard drive for my backup needs, actually the drive is mainly for backing up my music collection. For more important stuff, like my password lists, I usually keep copies scattered across multiple drives and machines.
I have been using software RAID-1 for years. Before that I relied on floppies, but my $HOME stuff became too much. I now have tens of gB in my $HOME. I am designing a new system for work which will have a 400 gB drive on USB to backup /home and my stuff with it. I will do periodic complete backups and daily snapshots of new files. I did look at the advanced backup systems, but they seem very complex. I prefer to simplify my system rather than complicate my backup... The new system will have four terminal servers with /home mounting via nfs from a two server failsafe cluster with heartbeat and drbd (RAID 1 over network) with backup scripts running. My own stuff lost would be a few days of anguish for me, but the new system will have 500 users so I would be publicly executed if anything goes wrong with their picture collections.
Distribution: Ubuntu, Debian, Various using VMWare
I have a Cron Job that runs rsync every 10 minutes, to a server on my LAN. This way, I will only lose a small portion of work in the event of a disk crash. This also prevents a loss if I accidentally delete a file - I simply copy the version off the server.
On a semi-regular basis, I backup the files on the server to DVD.
I didn't respond to the poll like I suspect others didn't, because (as some said) they should be check boxes rather than radio buttons to give correct answers.
I have a LAN and do the following to safeguard data and downloads:
1. Copy the "topic" directory structure to a NASlite server (a floppy initiated, and then run in memory) multiple large HDDs archive SMB server accessible to all users (two of us) as read-write. This can be a slow process, so is usually done while doing work on yet another computer.
2. If it's stuff others in the outside world might like to share (interesting downloads etc) I'll post it into one of several vhosts served by apache on one of the LAN machines, which has appropriate holes punched through the firewall. I'll probably duplicate the NASlite storage there anyway (for my own safeguard).
3. The originating computer will always have a spare data storage partition or HDD so that with a minimum of fuss a disaster can be overcome. This can also be slow.
4. Several of the LAN machines use plug-in HDD racks for the booting HDD, and a few less also have plug-in data storage HDDs.
5. Every bootable drive (obviously customised for specific computers) has its operating system archived; with reiser I have found my Norton Ghost is not succesful. This seems to work with earlier ext file systems, though, and of course MS Windows. The .gho files and downloaded .iso files for OS testing occupy a large proportion of the NASlite storage. .gho's are also kept on a seperate partition or drive on their own LAN machine.
I believe that this is a foolproof system and the advantage it has (for me) over CD or DVD storage is that unless you are very disciplined and destroy superseeded CDs or DVDs kept as backups, you can be in dead trouble lol!
I suppose each of us "rolls their own" to suit their MO. Don't know how useful my thoughts are.

I manually run some simple rsync scripts to backup files--FROM the file server TO local hard drives.
All of my "live" data is on my file server. That way, all data on all workstations is always "in sync"--it's all shared on the server.
That leaves a lot of free space on the local hard drives of the individual workstations. Thus, I have rsync scripts to maintain copies of various file server folders on the local workstation drives. For some of my particularly irreplaceable precious data, I have triple redundancy--quadruple redundancy if you include occasional backups to USB drives (portable media player).
