Hi all,
Can any body check, the steps to take the data backup on DVD.
please make corrections if I am missing some thing. or any other way to do this. All I need to take backup of .tar.gz files to DVDs.
I have installed dvd+rw-tools.
1. dmesg
The last few lines of /var/log/dmesg ( just wanted to know where this device is attached )
sr0: CDROM (ioctl) error, command: Xpwrite, Read disk info 00 00 00 00 00 00 00 02 00

cdrom: This disc doesn't have any tracks I recognize!
[B]Question[/B]:
Is this attached to sdc1 or sr0 ?? (Attached scsi CD-ROM sr0 at scsi3)
2. cdrecord -scanbus

[B]Question:[/B] Can any body tell me why we get output different when i run this command? like
scsibus2:
2,0,0 200) 'FREECOM_' 'DVD+/-RW20J6 ' '9F51' Removable CD-ROM
scsibus3:
3,0,0 300) 'FREECOM_' 'DVD+/-RW20J6 ' '9F51' Removable CD-ROM
3. mount -r -t iso9660 /dev/hdc /media/cdrecorder
4. To create the ISO image.
# mkisofs -r -o /tmp/home-backup-disk1.iso /home/backup
5. Now use the growisofs command to write the ISO onto the DVD.
# growisofs -Z /dev/dvd=/tmp/home-backup-disk1.iso
Will these steps work??
I was looking on some site where these commands were mentioned
[B][I]Backup a directory to a CD:
One step: mkisofs -r -R -J -l -L /home/user1 | cdrecord dev=0,4,0 -v --eject speed=4 -
or the two step variation of the process:
mkisofdot -o /tmp/backup.iso -graft-points "/home/user1=/home/user1"
cdrecord dev=0,4,0 -v --eject speed=4
Make sure directory does not hold more than CD capacity (700Mb typically). Check with the command: du -s /home/user1 [/I][/B]
Can any body explain the abouve bold and italic lines ??
tell me which way is good the steps i wrote or these commands? what if i need to use the blank part of the DVD again?
waiting for an earlier response.
Thanks.
