This is a common problem when writing to CD's or DVD's on any operating
system, not just linux. Because of the write-once nature of the media,
the files take on the read-only attribute. When you copy files back,
you just have to add the write attribute back with the chmod command.
I don't know if you want ALL of them writable, but this command would
add the write attribute to a whole tree:
chmod -R a+w *

If you're mainly talking about a disaster recovery solution, I have the
answer. It's a wonderful project called Mondo Rescue:
http://www.microwerks.net/~hugo/
We have just gotten our PC to switch from the SGI to the linux platform,
and the first thing I did was back up Bruker's installation before I
start tinkering with it. Mondo will backup your entire system onto ISO
cd images. Put in a blank hard drive, boot the first CD, and it will
restore the entire system. I intend to make new images every few
months. Sometime next week I'll send more detailed instructions to the
list.
Of course doing routine backup of files is a different matter.
