PostPosted: Sat 31 Dec 2005, 12:50    Post subject:  Need big help backuping files to CD  

Okay, here's the deal. I have a regular Puppy Linux 1.0.6 CD, and I'm trying to back up my files with it. My Windows XP installation has a trojan horse, and a worm, on it and so I can't use that.

Now I have 256 megs of RAM, and a 256 megabyte compact flash card in a USB cf drive, and 1 cd-rw reader/burner. Also, I have a 1.6 gigahertz Pentium 4 processor. And two hard drives each with NTFS partions. Crying or Very sad

Here's the problem. I can use Graveman to burn a small amount of info onto the cd, but the ramdisk is too small to hold a disk image the size of a regular cd. I don't have enough cd's to archive all the info I want to burn, if I can only burn 30meg cds.

Is there any way to burn directly to the CD, without the disk image being needed?

I'm not certain but you might be able to use the "dd" command. More info on using the "dd" command will be found in a thread in the Users forum.

If dd won't work for you, you might consider creating a (1 GB) swap partition on one of the drives, using Partition Magic.

read
/usr/share/doc/cdrtools/cdrecord.htm
in a Webbrowser.

If the overall speed of the system is sufficient and the structure of the filesystem is not too complex, cdrecord will run without creating an image of the ISO 9660 filesystem. Simply run the pipeline:


mkisofs -R /master/tree | cdrecord -v fs=6m speed=2 dev=2,0 -

This creates a Diskimage from files and folders in /master/tree , and sends it through a pipe ("|") directly to cdrecord.

To check, if the folder will fit on a CD, run

du -m /folder

In some cases du might not work exact, so add some MB tolerance (you just can find it out by trying).

Like this you can burn "parts" of your harddrive to CDs.

Um, this is the result I got. Apparently I'm doing something wrong.

Also, how do I burn several directories/files at once? Forgive me, I'm new to Linux and only 11 years old.

In a console, Spaces in Filenames do not work.
But you can do:
mkisofs -R "/mnt/hda2/Documents and Settings/Maximillian/My Documents/My Music/iTunes/" | cdrecord -v fs=6m speed=4 dev=1,0,0 -

That was error 1.
The second error:
You must tell it, what Device to use.

Do that:
Start graveman, and in "Settings" be shure your CD-burner is selected.
Exit graveman.
Now have a look at gravemans configurationfile.
Use the comand:
leafpad /root/.graveman/graveman.conf

It should have something like this:

Code:
[lecteur]
dev= 0,0,0
name=WDC WD20 00BB-55GUC0 Disk


So my Burner is "0,0,0".
So my final comand would be:
mkisofs -R "/mnt/hda2/Documents and Settings/Maximillian/My Documents/My Music/iTunes/" | cdrecord -v fs=6m speed=4 dev=0,0,0 -

If you burn directly, speed=4 might be too fast, if it does not work (buffer underrun) try speed=1

Does that work for you?

If you have questions, just ask.
I knew guys that were 13, that helped building http://pro-linux.de , which is germanys most famous Linux-Website Smile
So you have 2 more years time to become an "expert" Wink

Burning several folders at once:
No idea at moment, ... start - help - cdrtools - mkisofs

Seems to work like this:
mkisofs -R "/folder1" "/folder2" | ...

Guest,
Wonderful spelling and use of language for an eleven year old. Try using this it will help. Type part of command like just mki now press the [Tab] key. You should have gotten mkisofs I use it to get the correct paths when using windows. For your example if you have started to type Docu then [Tab] key in the command above, it would finish the name for you with the correct way of passing directory names with spaces, i.e. /mnt/hda2/Documents\ and\ Settings.... I can never recall the ways to correct those issues, but [Tab] key does.

I know that my CD-burner is at 1,0,0 because I used cdrdao a long time ago and figured it out. But thanks anyway. I tried it again, changing the settings and here is what I got:

Where did the SCSI drivers go?

Hm..

If you run "lsmod", does it list a scsi-driver?

If not, try
modprobe scsi_mod or insmod scsi_mod
or
modprobe usb-storage or insmod usb-storage

Try the usb also if it is no USB-burner, as I think those drivers are somewhat related.
Here are some other modules I have loaded:
Code:
sr_mod                 14488   0  (unused)
ide-cd                 29504   0
cdrom                  27744   0  [sr_mod ide-cd]



This is just a "wild" guess, as I do not really know a solution Embarassed

SCSI drivers appear intact. And here is what happens if you enter in the burning command.

By the way, how do you enable Joliet?
