Hello list,

I've been trying to figure out how to use my BD disc writer to create
backups of files.

What I first found were instructions to create an empty file of the
propper size, 'mkudffs file', loop mount it, copy files to it, unmount
and burn to the BD disc.

According to the internet K3B and Brasero are both able to burn BlueRay Data Disks. I haven't tried either of them with BlueRay though. 
 


I've not read the rest of the thread but I think you need to be careful
to set the blocksize in this use case.

In my notes I have:
mkudffs --blocksize=2048 $LD

(where LD is the loop device)



Hi Tim,

Thanks for the info, perhaps someday it may be useful.

The use of UDF was based on assumptions that later proved to be not valid and I am now using xorriso to create the image in ISO9660 format.

Bob
