On some systems users are allowed to use the CD-writer device. Your data will need to be formatted first. Use the mkisofs command to do this in the directory containing the files you want to backup. Check with df that enough disk space is available, because a new file about the same size as the entire current directory will be created:


[rose@blob recordables] df -h .

[rose@blob recordables] df -h .

The -J and -r options are used to make the CD-ROM mountable on different systems, see the man pages for more. After that, the CD can be created using the cdrecord tool with appropriate options:


[rose@blob recordables] cdrecord -dev 0,0,0 -speed=8 cd.iso Cdrecord 1.10 (i686-pc-linux-gnu) (C) 1995-2001 Joerg Schilling scsidev: '0,0,0'

scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.20

Using libscg version 'schily-0.5' Device type : Removable CD-ROM Version : 0

Response Format: 1 Vendor_info : 'HP '

Identification : 'CD-Writer+ 8100 ' Revision : '1.0g'

Device seems to be: Generic mmc CD-RW.

Using generic SCSI-3/mmc CD-R driver (mmc_cdr). Driver flags : SWABAUDIO

Starting to write CD/DVD at speed 4 in write mode for single session. Last chance to quit, starting real write in 0 seconds.

Operation starts.

Depending on your CD-writer, you now have the time to smoke^H^H^H^H^H eat a healthy piece of fruit and/or get a cup of coffee. Upon finishing the job, you will get a confirmation message:


Track 01: Total bytes read/written: 341540864/341540864 (166768 sectors).

Track 01: Total bytes read/written: 341540864/341540864 (166768 sectors).

There are some graphical tools available to make it easier on you. One of the popular ones is xcdroast, which is freely available from the X-CD-Roast web site and is included on most systems and in the GNU directory. Both the KDE and Gnome desktop managers have facilities to make your own CDs.
