How to burn a >4GB file on a dvd?

[pacho2]

When I try to burn I get the following error:

I'm now trying this possible solution https://forums.gentoo.org/viewtopic-p-3240716.html#3240716

It also fails with this:

The filesystem commonly used on CDs (and DVDs) is called ISO 9660 and only support files smaller than 2 GB. You should instead use the UDF filesystem which supports much larger files.

You could also use the split command, not really the best solution tho.

Mi /proc/config.gz:

Even with the -udf flag, mkisofs still generates the ISO9660 file system. There's no way to use mkisofs to put a >4GB file in a filesystem.
I don't know of any tools that will do it, but that doesn't mean they don't exist.

Hm, I'm sorry I couldn't really help here.
But if the problem lies in ISO9660, maybe creating only rockridge (-R I think) will do it. Disc won't be readable in windows then though.

Same problem

I use k3b to burn large files successfully. This is the mkisofs command it spits out, most of it is probably redundant though:

Are you sure the DVD is blank? It looks as if you are trying to burn a used disc, this is the clue:

You have to blank it...

Right, they don't have to be blanked.

Back on topic, I'm not sure what exactly mkisofs does when you specify the "-udf" option, but according to it's man page, mkisofs can't create an udf only image. I sorta guess the other part of the hybrid is always some sort of iso9660 filesystem, and you never will get around it with mkisofs...

If that's true, you have to use some other program to create a real UDF DVD. I only know mkudffs for that.

Now, if your burner supports it: By any means, use DVD-RAM; they're safer, more suitable for frequent rewrites, and they can be treated just like hard disk drives (just format and use them, no creating images or anything required!)

Anyways, there's also at least two ways of using DVD-+RW/R and UDF.
The more elegant one would be to use packet writing; it does some tricks to get similar writing to regular CD or DVD media as DVD-RAM or hard disk drives physically have. This tutorial should help.

If that doesn't work for some reason, you can always create your udf filesystem on your hard disk drive first (inside a regular, loopback mounted file if you have no free space for an additional partition), mount it, copy your data there, and then write the partition on your dvd. Instructions for that can be found in this thread.

Thanks

This tip doesn't work for me:

I only am able to copy 1 GB beacuse of a "size limit"

Same with https://forums.gentoo.org//viewtopic-t-377139-highlight-udftools.html

I get this error:

I can imagine why the second post you linked doesn't work since there the image there would be too small (only 200000 bytes), but I have no idea why it shouldn't work when you do it according to the first post. Is the error message the same? Is your image file on disk really large enough (try "df -h" and compare with your backup...)?

About using /dev/dvd directly... you say it worked without explicitly setting it up for packet writing, but just didn't take any file larger than 1GB?
