dvd-rw help <-- n00b with no clue

hello all!

here is the situation: i have been given the task of maintaining the database server here. one of my tasks is to archive the old data. i have the files ready to go, and a dvd-rw drive in the system. that's a dash rw drive (no + support afaik).

i have run some searches on how to burn data dvd-r's with linux (redhat 8.0 with NO gui in my case) and found information that is way beyond me, incomplete, or sounds sketchy.

can some kind soul help guide me in the right direction here? considering the cost of media, and the fact that this is a production system, i don't want to go out and burn a buch of coasters or crash the system.

thanks!!!

Which tool did you read up on?

dvdrecord is a patched version of cdrecord that supports burning dvd-r's.
you also need a patched mkisofs that supports files over 2 gigs for the
iso image. you also need to use a filesystem that supports over 2 gig files,
like reiserfs.

the command to make the iso image would be
/path/to/patched/mkisofs -r -J -o /file.iso /path/to/files/to/put/in/image

to burn the image
dvdrecord dev=0,0,0 -v -dao /file.iso

your device may be different.

if you add a -dummy after the -dao, a simple test burn will be run instead.
dvdrecord dev=0,0,0 -v -dao -dummy /file.iso

thanks whansard!

a couple of questions:
have you ever had any system stability issues with this process?
is the process the same for dvd+r[w] and dvd-r[w] media?

also, do i need to format or otherwise initialize dvd-rw media?

thanks again!

threw caution to the wind and went for it... :-)

didn't work and i don't know why... :-(

i make the iso, and mounted it on the loopback just to be sure it looked ok. then I ran the following command. brand new pioneer dvd-dash-rw media in drive...

Code:

dvdrecord dev=1,0,0 -v -dao ./mysqlback.iso

and got the following output:

i haven't had stability problems with it. i'll be burning disk and completely
forget, and i'll be web browsing and moving files around and stuff.
i've got the pioneer dvr-106.
i have no experience with dvd-rw's. i think there's a dvdrecord forum, but
i had trouble finding it. i would think you just have to blank dvd-rw's just
like you do cdrw's. there's a bunch of stuff that doesn't work right in
dvdrecord, like -speed and using it without -dao. i upgraded my firmware
a couple of months ago, hoping to add support for 2x disks that i had.
it didn't help.

it appears you are doing it correctly, but that's it's just not working for you.
except the second burn where it looks like you are trying to add a session.
so i guess that means that there was something on the disk already, and
with -dao, it's a write once deal.

thanks. when i get in tomorrow i will force a full blank of the disk, attempt the write again, and post the results.

thanks again!

i just burned some disks with cdrecord-DVDPro. it works better than
dvdrecord. it's free for personal use. i guess you can test it.

ftp://ftp.berlios.de/pub/cdrecord/ProDVD/README

downloaded cdrecord-prodvd and got the same errors... :-(

turned dma off and tried again... :-)

thanks!

does the smiley mean that it worked when you turned dma off?

yes it does. i forget where i read it, somewhere in an email archive i believe. a guy who was having similar errors turned off dma on the ide interface and had success, so i decided to try it and it worked like magic.

it's time to buy some burn once disks and burn about 100 gig of archives...
