How do I write CD at Debian Linux command prompt

We have couple of Debian Linux boxes with CD/DVD combo drive. We have an automated solution over network to backup all data everyday. However recently we decided to make backup of logs and few modified application on a CD. Don't ask me why but my manager asked me to do so. He said if not possible to take backup using command line fetch all files using ftp/http to windows XP and then write them :/?

Since I was aware of command line based cd-writing utilities, I told him I can do it on server itself. Here is my server setup:

P4 System running Debain Linux with custom compile 2.6.xx.xx series kernel. In order to write CDs at command prompt you need programs:
1)mkisofs – Create an ISO file image so that cdrecord can use the same to burn on a CD.
2)cdrecord – It is a utility capable of burning an actual disc i.e. ISO images created with mkisofs.
Since these packages were not installed I quickly run the commands to install it:
# apt-get install mkisofs
# apt-get install cdrecord

Configure cdrecord to write a CD

Under kernel version 2.6 you would not want to use ide-scsi for
CD-writing, the new kernel provides a superior access method that finally supports DMA access when writing CDs. Find out the device name used by your cdwriter i.e. find out the virtual SCSI ID of your device:
# cdrecord dev=ATA: -scanbusOutput:

As you see SONY CD-WRITER at 1,0,0. The comma separated number you need to pass to command line option as -dev=1,0,0. You can write an ISO image to CD with the following command:
# cdrecord -v -dev=ATA:1,0,0 speed=4 mydata.iso

Where,

• -speed=XX : Specify writing speed.
• -v : Verbose output.
• -dev : The virtual SCSI ID of your device

Here is an example, to create backup of /home/hosting-app/ directory:

a) Create an ISO file that can be opened on both windows and Linux computer:
$ mkisofs -v -o /tmp/happ.iso -R /home/hosting-app

b) Write an ISO (happ.iso) to CD i.e. burn an image:
$ cdrecord -v -dev=ATA:1,0,0 speed=4 /tmp/happ.iso

Read man pages of cdrecord and mkisofs for more information.
