Need Suggestions for Automated Backup

[Chong Yu Meng]

Hi All,

I'm going to be deploying another set of servers very soon and need to 
work out some kind of backup scheme for servers that will be running a 
database and several web applications.

I know that most people use a tape drive and cron job to backup stuff. 
However, right now my budget is really tight, and I was wondering how 
good CD-ROM backups are. I haven't heard of anyone using it, and I'm 
wondering if it is because they are unreliable. I'm thinking of the 
following scheme:

1. Tar all files to be archived into a humongous file
2. Mount CDROM drive (with blank CD inside)
3. Copy humongous tar file to CD
4. Unmount CD

All operations are to take place possibly around 4am local time.
