Split Backup Created By DD into CD or DVD sized files

burgsprinta · 12-08-2010, 09:44 PM

I am backing up parts of my computer with DD, and i was wondering if there was a quick way to split the files created into 4.4GB sized files that will fit onto a DVD. Anyone have any idea of how to do this? Thanks

You can do that with the split-command, in your case it would look like:

Code:

split --size=4400M YOURIMAGEFILE

Of course you have to replace YOURIMAGEFILE withb the actual name of your imagefile. The command will create the files x01, x02, x03, ...

For further info look at

Code:

man split

Thanks a lot. Seems to be working perfectly.

Have you tried burning them to a DVD ? You may find that it won't work, because the limit is 2GB per file. You can do it with this command:

Code:

growisofs -M myiso.iso -graft-points -rational-rock -full-iso9660-filenames -iso-level 3 -udf <filestoadd>

Note that using iso level 3 will prevent it from working on anything but a computer (don't know about Window$).

Or you can split the files to less than 2GB and burn normally.

Didn't know that, every time learning on LQ.

I learned by trying it...

Didn't know that either. I hadn't tried burning the files yet. Thanks.
