Command line file copy to CD

[gogalthorp]

I need a command line program to burn a directory to a cd-R. ie so I can use a script and set up a cron job. I need to back a directory periodicly and automaticly.

Can anyone give me some direction here?

I have a SUSE book here that suggests to use a program called "Konserve". You may already have it on your system. check K menu > System > Desktop Applet > Konserve Apparently it allows for scheduled backups and I wouldn't be surprised if you could kick it off with a cron entry.
Other than that, the command line cdrecord will send files to CD-R and CD R/W.

Thanks

cdrecord seems to only support SCSI devices???

I'll look for Konserve it does not appear on my menu.

Ok found konserv

looks like it only backups to directories.

cdrecord seems to be SCSI only. It did not recognize my CD/DVD burner on my current machine.

In this case this is a stand alone machine no network no internet.

I need to backup to cds automaticly. I can't believe no one is doing this. All the backup programs I've found so far simply make a compressed image of some sort to a folder on the machine or network. You then need to manualy transfere this to a cd. But I have really dumb users in this case and can't trust them to do it correctly. I'm running a POS and we are talking video store clerks here.

does not have to be open source!!! but would prefer it

OOps I guess it cdrecord might work. I must have typed something wrong the last I check but it is now showing my cd writer as a device. cool

But you still must build an iso image before the burn.

A script can help

Use mkisofs and cdrecord

I am doing exactly the same thing without a glitch using
tar -cvzf file.tar.gz {folders}
mkisofs file.tar.gz /tmp/file.iso # intermediary step
cdrecord -v -dao dev=x,0,0 file.iso
rm -rf /tmp/file.iso # intermediary disc cleanup


Is there any way to write directly to cd-r ? I wrote to the cd-r using tar -cvzf /dev/cdwriter folder, but the cd was trash dump for obvious reasons.

Is there any other work around?

Walla!!!
I got the answer:

mkisofs -R {source_file} | cdrecord -v fs=6m speed=2 dev=x,x,x

where

-R enables Rock Ridge protocol in order to describe iso 9660 format for the cd media
x,x,x can be get cdrecord -scanbus
fs describes the non-default buffer size (default 4MB)
