Try squashfs - this is a compressed filesystem which is being used a lot for liveCDs. It also achieves better compression than JFFS2.
I really don't care about compression, but I suppose it doesn't hurt.
Squashfs is read-only, but it does support appending to the filesystem. This was added specifically to support incremental backups.
But how is this used on a DVD-RW?
1) You have a squashfs disk image and append to it, writing the final image to the CD/DVD when a certain size is reached?
2) You use a CD/DVD-RW (with UFS or whatever) and update a squashfs image file on the disk?
If it's 1) then it doesn't matter what filesystem is used. If it's 2), it's nice for incremental backups, but it will not allow you to take advantage of the fact that you can delete files on a -+RW disk (but good for -+R disks).
Hope it's 3)...
