You need to activate the Rock Ridge extensions, not Joliet (or both).
Ah, of course ... thanks for reminding us, Carlos. It's been several years since I last did any serious backups to CD/DVD so I guess I'd forgotten. That being said, I seem to recall also compressing first to reduce the number of disks I was burning and this, coincidentally, also served to preserve the attributes.
Compression... well, not really the compression part, but the archiving part. When in the Unix/Linux world you create an archive, like a 'tar', the attributes and permissions are stored inside the archive. Thus, when you copy the archive, compressed or not, to a CD or tape or HD, they are preserved. I personally dislike compressed tars for backups. A single byte error in the media, and you can not decompress it. The entire tar archive is lost. Very unreliable. There is a compression extension for CD/DVDs. The DVD can be mounted normally, and the contents are transparently decompressed on the fly, so you get direct access to any files in there. However, the process of creating a compressed DVD is cumbersome. Look up the -z parameter in the "genisoimage" man page (old mkisofs). -- Cheers / Saludos, Carlos E. R.
